ENERGY 50 KEY 2	Kinetic Plating Generate armor plating that converts a portion of absorbed kinetic damage (Physical, Heat, Cold, and Blast) into energy. Also protects Gauss from being staggered or knocked down. Damage resistance is relative to the battery level. Battery drain per second: 1.28% s^-1	Strength:14 - 70% / 16 - 80% / 18 - 90% / 20 - 100% (damage reduction)
		Duration:15 / 20 / 25 / 30 s (duration)
		Range:N/A
		Misc:1.0 - 6.5% (battery drain per hit) ?% (battery charge per melee attack) 2 / 3 / 4 / 5 % (energy restore per hit) 50% (damage reduction cap at empty battery) 100% (damage reduction cap at full battery) 100% ( Slash status chance for Mach Rush) 100% (base melee damage bonus and stagger chance from Redline)

Gauss shields himself in a barrier of kinetic energy with one swift motion, protecting himself against incoming Impact, Puncture, Slash, Cold, Heat, and Blast damage types as well as their respective status effects, while also becoming immune to stagger and knockdown effects for 15 / 20 / 25 / 30 seconds. While active, Kinetic Plating drains 1.28% battery power per second and 1.0% to 6.5% battery power per hit received, to reduce affected damage by a minimum of 14% / 16% / 18% / 20% at empty battery, up to a maximum of 70% / 80% / 90% / 100% at full battery. 2% / 3% / 4% / 5% of damage absorbed per hit is converted into extra Energy for Gauss. Melee attacks while Kinetic Plating is active will restore ?% battery. Kinetic Plating deactivates on duration end or by manually pressing the ability key again (default 2 ).
- Duration is affected by Ability Duration.
- Damage reduction scales with battery level and is affected by Ability Strength. Maximum damage reduction cannot exceed 100%. Minimum damage reduction cannot exceed 50%.
  - Damage reduction is calculated as:
    $Min Damage Reduction + (Max Damage Reduction - Min Damage Reduction) \times Current Battery Level$
  - For example, with Kinetic Plating at rank 3, 100% Ability Strength, and battery level at 80%, the damage reduction will be: $20% + (100% - 20%) \times 80% = 84%$
- Battery drain per second, battery drain per hit, energy restore per hit, and battery charge per melee attack are not affected by Mods.
- Battery drain per hit is dependent on the damage of the attacker up to a cap of ~6.5%. Melee hits blocked generally drain less battery.
- Both damage reduction and energy restoration still function even when the battery is empty.
Ability Synergy:
- While Kinetic Plating is active, it adds 100% Slash damage to Mach Rush's shockwave, and makes it inflict a Slash proc on enemies caught in the explosion radius.
- While the battery level is boosted during Redline, Kinetic Plating also grants Gauss a 100% base melee damage bonus and 100% chance to stagger enemies on hit.

Kinetic Plating stacks and synergizes well with Adaptation.
- Kinetic Plating provides initial protection while Adaptation builds up damage resistance from 0% to 90%.
- Though Kinetic Plating's damage resistance can reach 100% at full battery, it cannot cover all damage type and the battery would't be full for most of the time.
- On the other hand, Adaptation can reduce only one damage type for each particular attack.
Kinetic Plating stacks with Hunter Adrenaline and, when combined, can quickly restore energy while under heavy fire.
Kinetic Plating synergizes well with Quick Thinking as it reduces energy drain upon fatal hit, and also compensates with its energy restoration.
Kinetic Plating does not require high Ability Strength to be viable as its damage reduction is primarily scaled with battery level.
- Damage reduction will be 84% with 100% Ability Strength at 80% battery level.
- This can be scaled up to 90%, which requires 250% Ability Strength.
- However, at full battery, damage reduction will reach 100% if Ability Strength is 100% or more.

ENERGY 75 KEY 3	Warding Halo Create a protective ring of fire, that also stuns and damage enemies who get too close.	Strength:500 / 650 / 800 / 1000 (base health) 50 / 75 / 100 / 125 ( Slash damage per second) 1.15x / 1.25x / 1.75x / 2.50x (armor multiplier) 2.5x (absorption multiplier)
		Duration:N/A
		Range:1.25 / 1.5 / 1.75 / 2 m
		Misc:3 s (invulnerability duration)

Nezha summons a fiery ring that encircles him, granting full immunity to status effects, and absorbing 90% of all incoming damage. The ring starts with 500 / 650 / 800 / 1000 base health, to which 115% / 125% / 175% / 250% of Nezha's total armor is added as bonus health. Upon activation, the ring is invulnerable for 3 seconds, during this time all incoming damage it takes is multiplied by 250% and added to the its total health. Enemies that wander within 1.25 / 1.5 / 1.75 / 2 meters of Nezha are continuously staggered and dealt 50 / 75 / 100 / 125 Slash damage every second. Warding Halo cannot be refreshed while it is active, and only expires when its health is depleted or when it is dispelled.
- Damage reduction affects Overshield, Shield and Health.
- Warding Halo's Base health, armor multiplier, absorption multiplier and damage per second, are affected by Ability Strength.
- Warding Halo's health uses the following expression when accounting for Ability Strength:
  Modified Health = (Base Health + Armor Multiplier × (Health Conversion Armor + Nezha's Base Armor × (1 + Armor Bonus)) + Absorbed Damage × Absorption Multiplier) × (1 + Ability Strength)
  - As an example, with a maxed Steel Fiber and Intensify, and one stack on Health Conversion, a rank-3 Warding Halo will have an initial health of $(1000 + (2.5 \times (450 + 190 \times (1 + 1.1)))) \times (1 + 0.3) = 4,059.25$ before absorbing damage.
- Invulnerability duration is not affected by Ability Duration.
- Stagger radius is affected by Ability Range.
- While active, a health counter is displayed on the lower-right of the HUD, above the ability icons, indicating how much damage absorption is left.
- Slash damage instances immediately affect enemies as they enter the stun radius.
- Status effect immunity includes crowd-controlling effects such as knockdowns and staggers. Energy drains from Ancient Disruptors, including the small amounts of energy they drain with each melee attack, are resisted. However, Eximus energy drains and the speed reduction caused by the mucus of Tar-Mutalist MOAs are not resisted by Warding Halo.
- Cast animation of ~1 second is affected by Natural Talent and Speed Drift.
  - Casting this ability makes Nezha stop all other actions, including movement. However, players can perform a running slide and hold it before casting in order to maintain momentum during the animation.
Warding Halo will release a wave of heat outward when it expires, inflicting all surrounding enemies with 100% Heat status effect, and making Nezha invulnerable for 1 second.
- Warding Halo cannot be cast while active, but can be recast during this expiry invulnerability period.
- Damage taken from the last hit which exceeds the health of Warding Halo will still transfer over in full to Nezha's health, potentially killing them (if strong enough), before the 1 second invulnerability can take effect.
Blocking with a melee weapon will not reduce damage taken to Warding Halo's Health, but will reduce damage taken from the 10% that is not absorbed by Warding Halo.

Main article: Safeguard

Safeguard is a Warframe Augment Mod for Nezha that allows him to cast Warding Halo on allies, albeit with reduced durability.

Rank	Durability	Cost
0	20%	6
1	30%	7
2	40%	8
3	50%	9

Using Health Conversion to gain armor stacks before casting Warding Halo, greatly increases its base health without requiring as much Power Strength.
Be careful against enemies like Mutalist Osprey. Their toxin cloud for example deals damage to your Warding Halo and to your HP, bypassing your shield. This can kill you very easily, even with a full Warding Halo.

ENERGY 0 KEY 3	Parasitic Link Bind to a target with parasitic link. When cast on an ally, both the host and Nidus have their Ability Strength increased. Linked enemies take some of the damage inflicted on Nidus. Mutation Stacks Cost: 1	Strength:N/A
		Duration:30 / 35 / 45 / 60 s
		Range:24 / 28 / 34 / 40 m (ally link) 10 / 13 / 16 / 20 m (enemy link)

Nidus expends a single Mutation stack to perform symbiosis with a targeted ally Warframe within 24 / 28 / 34 / 40 meters or parasitically link with a targeted enemy within 10 / 13 / 16 / 20 meters. The link persists as long as Nidus and his target remain in range of each other, lasting for 30 / 35 / 45 / 60 seconds or when manually deactivated by pressing the ability key again.
- Ally and enemy link range are affected by Ability Range.
- Duration is affected by Ability Duration.
- Parasitic Link does not require line-of-sight to maintain connection between Nidus and his target.
- If the target dies during cast before the link is attached, the single Mutation stack used for Parasitic Link will be refunded.
When linked with an ally Warframe, Nidus and his target both receive a 10% / 15% / 20% / 25% Ability Strength bonus. When linked with an enemy, the target is completely disabled for the duration while Nidus transfers 20% / 30% / 40% / 50% damage received to the target instead; all knockdown, stagger, and negative status effects are also transferred from Nidus to the enemy target.
- Ability Strength bonus and damage redirection are affected by Ability Strength.
- Parasitic Link's Ability Strength bonus affects Ability Strength multiplicatively using the following expressions:
  $Modified Strength Bonus = Strength Bonus \times (1 + Ability Strength)$
  - With a maxed Intensify and the 15% Ability Strength rank bonus, Nidus will have 145% Ability Strength, resulting in $0.25 \times (1 + 0.3 + 0.15) = 36.25%$ Modified Strength Bonus displayed on the UI.
    $Modified Ability Strength = (1 + Ability Strength) \times (1 + Modified Strength Bonus)$
  - Modified Strength Bonus then increases Ability Strength multiplicatively, granting $1.45 \times (1 + 0.3625) = 197.5625%$ Modified Ability Strength that affects Nidus' other abilities while a rank-3 Parasitic Link is active.
  - The Modified Strength Bonus is the same percentage for your linked ally. However, Modified Ability Strength's calculation will depend on your linked ally's own Ability Strength.
- Damage redirection is capped at 90%, achievable with an Ability Strength of at least 180%.
- Enemy target is invulnerable to outside sources of damage and immune to external crowd control effects while Parasitic Link is active, but is not immune to damage and crowd control effects transferred from Nidus. Damage from outside sources is accumulated and dealt to the target when the ability expires or is manually deactivated.
  - Friendly fire is not transferred to the linked target.
Ability Synergy: While linked to a target, using Virulence will spawn a second instance from the linked target that grows towards the targeted location, converging with the first instance from Nidus.
- Enemies hit by the second instance separately counts toward Mutation stack, even when the same enemies also get hit by the first instance.
Parasitic Link is a One-Handed Action and can be cast while in midair.
Nidus and the target are visibly covered in infestation and connected via a tether of biochemical energy, which is affected by the chosen Warframe energy color.
Cannot link to a target already affected by Parasitic Link. Multiple Nidus players cannot link to the same target, nor to each other while their own Parasitic Link ability is active.
When connected to another Nidus player, both players will use the Ability Strength bonus from the casting player; the link will break if the partner activates Parasitic Link on a different target.

Link with a nearby teammate or enemy for Virulence to create two lines from Nidus and the linked target. This effectively extends Virulence's reach, doubles its damage output, staggers enemies in its paths, collects more hits for stacks, and earns extra energy for the cost of one cast.
- Linking with a teammate creates a mobile casting point that can relocate quickly to find new enemies.
- Linking with an enemy provides a stationary casting point that allows you move around to adjust Virulence's travel direction and length.
- Use Virulence's range indicator by holding 1 to determine the number of targets both lines will hit before releasing the button to cast.
Teammates with Warframes that possess high ability damage and Ability Strength-based effects are prime candidates for Parasitic Link.
- Alternatively, the Ability Strength bonus allows allies to use more balanced builds instead of builds that focus solely on Ability Strength.
Enemies with high health and armor values such as Heavy Gunners can absorb a large amount of damage transferred from Nidus.
As long as Nidus and his target are in range of each other, Parasitic Link's biochemical tether will help you visually track your positions.
Before reviving a downed teammate, link with a nearby enemy to protect yourself from taking too much damage.
Linking with an enemy caught by Larva causes it to become immune to damage from outside sources, which may hinder your crowd control ability because Larva will go through its full duration before you can recast it. Press 3 to manually deactivate the link, allowing you and your allies to kill the enemy to end Larva early for recast.
- This immunity to damage can be beneficial for racking up the melee combo counter. Simply attack the target as many time as possible. Combine with combo mods like Blood Rush for best results.
Maggots from Ravenous will ignore your linked enemy target. However, maggot explosions will still count as hits for the Mutation gauge even when they cannot damage the target. When you cast Parasitic Link on an enemy with maggots attached, the maggots will detach once the link is established.
Parasitic Link can be cast on the Juggernaut, and though it will not immobilize the Juggernaut it will still transfer damage to it, bypassing the Juggernaut's normally-impenetrable armor.
Can be used to immobilize Synthesis target, instead of deploying Kinetic Siphon Trap. This also prevents the target from being killed, accidentally or not, provided Nidus himself is not under heavy fire.
Parasitic Link can transfer negative Conduit Effects given in Disruption. For example, Energy Drain will drop from 5 energy per second to 1. This reduces, but does not negate, the threat of negative effects from conduits, should one fail.

ENERGY 50 KEY 2	Hallowed Ground Sanctifies the ground before Oberon with righteous fire, inflicting damage to any enemy that stands in the flames.	Strength:N/A
		Duration:10 / 15 / 17 / 20 s
		Range:90 / 100 / 120 / 180° (angle) 8 / 10 / 12 / 15 m (radius)

Oberon consecrates the ground in an angle of 90 / 100 / 120 / 180 degrees in front of him, spanning up to 8 / 10 / 12 / 15 meters, for 10 / 15 / 17 / 20 seconds. Enemies standing on the area of effect are dealt 25 / 50 / 75 / 100 Radiation damage with a 5 / 10 / 12 / 15% Radiation status chance every half second, while allies are relinquished of any negative status effects and become immune to them for as long as they are standing on the area.
- Damage and status chance are affected by Ability Strength.
- Duration is affected by Ability Duration.
- Radius and angle are affected by Ability Range.
  - The radius follows the expression:Base Range + 11.25 × (Ability Range - 1)
    - For example, with a maxed Stretch, the radius will increase to
      $15 + 11.25 \times (1.45 - 1) = 20.0625$ meters.
  - The angle follows the expression Base Angle + 135° × (Ability Range - 1)
    - For example, with a maxed Stretch, the angle will increase to
      $180° + 135° \times (1.45 - 1) = 240.75°$ ).
    - Therefore, 234% Ability Range is needed to bring the angle up to 360°, making it a full circle. This will also increase the radius to $15 + 11.25 \times (2.34 - 1) = 30.075$ meters.
Status effect immunity applies to physical disabling effects such as knockdowns and staggers.
- It does not apply to Eximus energy drains or Nauseous Crawler disables. Magnetic procs from Ancient Disruptors are resisted; however, Disruptors are still able to drain a small amount of energy with every attack.
- Radiation procs, however, are not removed from already irradiated allies, but only from Oberon himself, and only with his own Hallowed Ground.
Enemies and allies must be grounded and standing on the area to be affected by Hallowed Ground.
- Flying enemies that are too high above the ground may not be affected by this ability.
Ability Synergy:
- If Oberon or any allies affected by Renewal stands on Hallowed Ground, they will receive the Iron Renewal buff, which grants 125 / 150 / 175 / 200 bonus armor for as long as Renewal is active. Once Renewal is deactivated, the armor buff will remain on all affected units for 20 more seconds.
  - The armor bonus is affected by Ability Strength.
  - Bonus armor is added after other armor increases (e.g. an Oberon with a maxed Steel Fiber and Intensify will have $(150 \times 2.1) + (200 \times 1.3) = 575$ armor).
  - Buff duration is affected by Ability Duration.
  - As Link Armor scales with the player's armor, companions with this mod benefit twice from Iron Renewal, as the companion links into the player's increased armor and then gets buffed by Iron Renewal.
- Enemies that survive Reckoning while standing on Hallowed Ground will have their armor permanently reduced by 10% / 15% / 20% / 30%.
  - Armor reduction is affected by Ability Strength.
    - Armor reduction is applied to the enemy's base armor when accounting multiple casts.
Can only have 4 instances of Hallowed Ground active at once per player.
If cast in midair, Oberon will instantly drop to the ground to perform this ability.
Hallowed Ground spawns foliage inside its area of effect as visual representation. Oberon creates a field of grass, while Oberon Prime creates a field of ferns. Grass and ferns are affected by Oberon's chosen Warframe Accent color.
- The shimmering energy field encompassing the ground is affected by Oberon's chosen Warframe energy color.

Main article: Hallowed Eruption

Hallowed Eruption is a Warframe Augment Mod for Oberon. Upon casting Hallowed Ground again with a previous instance still active, the first one will immediately expire, dealing all remaining damage in a single instance with a chance to deal Radiation proc. This mod also passively increases Hallowed Ground's duration.

Rank	Status Chance	Bonus Duration	Cost
0	30%	25%	6
1	50%	50%	7
2	70%	75%	8
3	100%	100%	9

Enemies will traverse and fight through Hallowed Ground without any special attempts to evade its area of effect.
Narrow pathways such as doorways and halls are effective at forcing groups of enemies to cluster into Hallowed Ground.
Summoning multiple, overlapping layers of Hallowed Ground will deal the full combined damage over time to enemies.
Hallowed Ground is most efficiently used in areas where constant enemy and ally activity is expected over an extended period of time.
Hallowed Ground's status effect immunity can be used to pass through environmental traps unhindered, such as Grineer Magnetic Sensor Bars and Corpus Laser Barriers.
- Note however that activating these traps in spy missions will still trigger vault alarms.
Hallowed Ground will make players immune to to Radiation and Magnetic singularities in Sorties.

ENERGY 50 KEY 2	Iron Skin Rhino hardens his skin, insulating himself from all damage.	Strength:400 / 600 / 800 / 1200 (base health) ? / 1.25 / 1.75 / 2.50x (armor multiplier)
		Duration:N/A
		Range:N/A
		Misc:1.5 / 2 / 3 / 3 s (invulnerability duration)

Rhino hardens his skin to create a reinforcing buffer with 400 / 600 / 800 / 1200 base health. Rhino's total armor multiplied by 250% is also added to the buffer's health. Upon activation, Iron Skin is invulnerable for 1.5 / 2 / 3 / 3 seconds. All incoming damage that is absorbed during this invulnerability period is converted into health and added to the buffer's health. While the Iron Skin is active, Rhino becomes immune to damage and status effects. Iron Skin will expire when the buffer's health is depleted.
- Iron Skin's total health, before absorbing damage, is multiplicatively affected by Ability Strength.
- Iron Skin's health uses the following expression when accounting for Ability Strength:
  $Modified Health = (Base Health + (Armor Multiplier \times Base Armor \times (1 + Armor Mods))) \times (1 + Ability Strength) + Absorbed Damage$ .
- Note that the base armor value is different between Rhino and Rhino Prime; while Rhino has 225 Base Armor, Rhino Prime has 275 Base Armor.
- As an example for Rhino:
  - With a maxed Steel Fiber and Intensify, a Rank 3 Iron Skin cast by Rhino will have an initial health of $(1200 + (2.5 \times 225 \times 2.1)) \times 1.3 = 3,095.625$ before absorbing damage.
- Modifying that equation for Rhino Prime:
  - With a maxed Steel Fiber and Intensify, a Rank 3 Iron Skin cast by Rhino Prime will have an initial health of $(1200 + (2.5 \times 275 \times 2.1)) \times 1.3 = 3,436.875$ before absorbing damage.
- While active, a health counter becomes visible on the ability icon that tracks Iron Skin's health percentage from 100% to 0%.
- The amount of health gained from absorbed damage is displayed in the HUD beside Rhino's shield and health indicators while Iron Skin is invulnerable.
- Despite invulnerability, status effects are not ignored during that period, allowing debilitating status effects such as knockdown and cold procs to occur until Iron Skin fully activates.
- Invulnerability duration is not affected by Ability Duration.
- Status effect immunity includes crowd-controlling effects such as knockdowns and staggers. Energy drains from Ancient Disruptors, including the small amounts of energy they drain with each melee attack, are resisted. However, Eximus energy drains and Nauseous Crawler disables are not resisted by Iron Skin.
Iron Skin protects Rhino's health from damage that bypasses shields such as Toxin damage.
Allows Rhino's shields to regenerate while active.
Can be used to both block and pass through Corpus Laser Barriers and Grineer Sensor Bars.
Blocking with a melee weapon does not reduce damage taken while Iron Skin is active.
Using Iron Skin will not stop the health damage taken in the Vampire Challenge of Nightmare Mode. However, Iron Skin will not be drained.
When the air runs out in Survival, Iron skin will deplete almost immediately and recasting it will cause it to dissipate near instantly.
Damage resistance on Rhino, like Trinity's Blessing, other similar Warframe Abilities, and mods like Adaptation do not apply to Iron Skin (this list includes Armor).
Iron Skin uses object health, so incoming damage is not modified by type and cannot crit.
Ability Synergy: While Iron Skin is active, damage from Rhino Charge will have a 100% status chance for Blast effects.
For Rhino Prime, Iron Skin's visual effects will take into account the chosen accent color. It is otherwise functionally identical.
Can be activated while sliding, jumping, forward flipping, wall running, or wall clinging.

Main article: Iron Shrapnel

Iron Shrapnel is a Warframe Augment Mod usable in both PvE and Conclave for Rhino's Iron Skin that when active allows it to be detonated by pressing the ability key (default 2 ), unleashing a radial AoE attack that deals a portion of its remaining health as Puncture damage.

Rank	Damage	Proc Chance	Cost
0	40%	30%	6
1	60%	40%	7
2	80%	50%	8
3	100%	60%	9

Ironskin can be removed early by:
- Entering the bubble of a Nullifier Crewman (Corrupted)
- Entering the aura range of Combas & Scrambuses
- Being dispelled by Stalker
- Falling out of the map.
- Host Migration
With a Streamline or Fleeting Expertise mod, Rhino can cast Iron Skin immediately after the first Energy Drain tick in order to give himself a "shield" of sorts.
It is possible to gain a significant amount of health for Iron Skin by standing in the path of a Death Orb beam during the invulnerability phase. Be warned however, as the beam can quickly deplete said health if the player does not move out of the way once the invulnerability phase ends.
Using Rhino Charge with Ironclad Charge installed before casting Iron Skin can significantly boost its health by boosting the armor.
- By this method, you can easily reach over 50k of Iron Skin health by charging into a group of enemies when invested in armor and ability strength.
- Ironclad Charge's armor bonus is applied to Iron Skin as long as Iron Skin's casting was started in the duration of the buff.
  - Iron Shrapnel can help by providing the ability to re-cast Iron Skin at any given time, even with extremely lowered ability duration as long as you cast Iron Skin right after a Rhino Charge.
Arcane Tanker can significantly provide armor boost, effectively increasing Iron Skin's health by roughly over 100%.

Migrating hosts will completely remove Iron skin, regardless of the level it was at.
If Rhino manages to activate Iron Skin as he falls backwards and enters bleedout, his bleedout timer will reach zero and he will never die. He will remain in bleedout until he is revived.
Procs from Blast damage can knockdown the player even if Iron Skin is still active.
Using Iron Skin while in a conveyor would make Rhino immovable.

ENERGY 25 KEY 1	Spellbind Enemies fumble their weapons as they tumble into the air. Nearby allies become immune to Status Effects. Hold the ability to cast the immunity onto Titania.	Strength:N/A
		Duration:10 / 12 / 14 / 16 s
		Range:1 / 3 / 3 / 5 m (area radius) 20 / 30 / 40 / 50 m (cast range)
		Misc:100 % (status cleanse and immunity)

Titania scatters enchanted dust in a 1 / 3 / 3 / 5 meter radius around the location she aims at, up to 20 / 30 / 40 / 50 meters away. Enemies within this area are disarmed, become unable to perform any action while in a ragdoll state, and weightlessly float in mid-air for 10 / 12 / 14 / 16 seconds. Titania and her allies caught within the dust cloud are cleansed from status effects and gain immunity to them for the duration of the ability. Holding down the ability key (default 1 ) casts the ability point-blank from Titania.
- Cast range and area radius are affected by Ability Range.
- Duration is affected by Ability Duration.
- Cast animation of 1 second is affected by Natural Talent and Speed Drift.
  - Can be cast while moving, but will interrupt other actions such as reloading, charging or shooting.
- Status cleanse and immunity are not affected by mods.
- Status immunity also protects from crowd control effects (such as knockdowns and staggers), including the lock-out animation of Archwing and Razorwing when impacting a surface.
Enemies affected by Spellbind will float away in the direction of their movement depending on their velocity and momentum at the time of cast. Hit-scan, projectile, and melee attacks can cause spellbound enemies to ricochet in random directions.
After Spellbind expires, enemies previously armed with weapons cannot attack until they retrieve their weapons from their initial position. Those that do not use weapons (such as the Infested) will recover quickly.
Recasting on Titania or an ally will refresh the status immunity.
Spellbound allies and enemies emit unique particle effects:
- Enemies visually emit energy butterflies fluttering about and an upward stream of energy stripes, both affected by Titania's energy colors.
- Allies visually emit energy butterflies fluttering about, affected by their own energy colors.
Spellbind can be aimed at any surface, but will only allow you to use it if an enemy is within the predicted area of effect.
Subsuming Titania to the Helminth will offer Spellbind and its augments to be used by other Warframes.

Main article: Spellbound Harvest

Spellbound Harvest is a Warframe Augment Mod for Titania which lets her regain Energy when hitting at least 4 enemies with Spellbind.

Rank	Energy granted	Cost
0	20	6
1	30	7
2	40	8
3	50	9

The status immunity granted by Spellbind also prevents Titania from being staggered when hitting surfaces in Razorwing. Holding the button down to activate Spellbind on yourself can be really helpful when flying through tight spaces.

ENERGY 75 KEY 3	Link Any damage taken while Link is active will be channeled to a nearby enemy.	Strength:N/A
		Duration:6 / 8 / 10 / 12 s
		Range:12 / 14 / 17 / 20 m
		Misc:1 / 2 / 2 / 3 (affected enemies) 50% / 60% / 70% / 75% (damage reduction) 100% (damage and status transfer)

Imbuing herself with defensive energy, Trinity tethers to up to 1 / 2 / 2 / 3 closest enemies within a radius of 12 / 14 / 17 / 20 meters for 6 / 8 / 10 / 12 seconds. While linked, she reduces incoming damage to herself by 50% / 60% / 70% / 75% and transfers 100% of incoming damage and Status Effects to the tethered enemies instead.
- Radius is affected by Ability Range.
- Duration is affected by Ability Duration.
- Casting time of 0.6 seconds is affected by Natural Talent and Speed Drift.
- Number of affected enemies, damage reduction, and damage and status transfer are not affected by mods.
- Trinity must be linked to at least one enemy at any given moment to gain the ability's defensive benefits.
- Status immunity applies to physical staggers and knockdown.
  - Includes knockdown from environmental traps such as Corpus Laser Barriers. Note that tripping these barriers in Spy missions will still trigger vault alarms.
- Status effect immunity does not include Eximus energy drains or Nauseous Crawler disables. Magnetic procs from Ancient Disruptors are resisted; however, they are still able to drain a small amount of energy with every attack due to their aura.
Ability Synergy: damage redirected by Link toward a Well Of Life target heals Trinity for the lifesteal conversion amount, as well as becomes stored and dealt in full against the Well of Life target once the ability ends.
If Trinity is bleeding out while this ability is active, she will not link with nearby enemies.
Trinity cannot link with The Stalker.
Although it will mitigate damage from Ancient Healers and Corrupted Ancients it will not hurt them due to how they absorb damage from nearby allies.
Trinity and linked enemies will shine the color of her energy.
Cannot be recast while active.
Casting Link is a full-body animation that stops grounded movement and all other actions.

Main article: Abating Link

Abating Link is a Warframe Augment Mod for Trinity's Link that reduces the armor of all connected enemies.

Rank	Armor Reduction	Cost
0	25%	6
1	30%	7
2	35%	8
3	45%	9

Keeping this ability active when surrounded by high-level enemies will dramatically increase Trinity's survivability.
- Be careful of Link's slow, immobile cast delay, lest you become overwhelmed by burst fire.
Use Trinity's Energy Vampire to fuel Link's high energy cost.
Link connects to enemies through walls and other obstacles, which serves as an early-warning system indicating if enemies are nearby.
- Similarly, Link can connect to and track the position of cloaked enemies such as Capture targets and Manics.
Be wary of mods and effects which reduce Ability Range as they make it harder to maintain an active link, and with that, Link's defensive benefits.

ENERGY 25 KEY 4	Hysteria Valkyr is imbued with energy and becomes a ball of vicious rage, capable of unleashing a torrent of deadly claw attacks on unsuspecting foes. Minimum Energy Drain: 2.5 s^-1 Maximum Energy Drain: 15 s^-1	Strength:100 / 125 / 200 / 250 (damage)
		Duration:N/A
		Range:N/A
		Misc:1% / 2% / 4% / 5% (lifesteal) 5-20 m (aura radius)

Overcome with rage, Valkyr unleashes a pair of energy talons, the Valkyr Talons, as her melee Exalted Weapon. Normal attacks deal 100 / 125 / 200 / 250 damage within 2 meters.
- Damage is distributed evenly between Impact, Puncture, and Slash.
- Wall attacks and slide attacks inflict 300 / 375 / 600 / 750 damage for each strike.
- Aerial attacks inflict 200 / 250 / 400 / 500 damage.
- Slam attacks inflict 300 damage within 5 meters.
Attacks have a 200% critical multiplier with a 50% critical chance and a 10% status chance. Additionally, Valkyr is healed for 1% / 2% / 4% / 5% of the total melee damage she inflicts.
Damage is affected by Ability Strength, the Melee Combo Counter, most mods, and buffs.
- As an example, with a maxed Pressure Point, Shocking Touch and Intensify, the normal attacks of a rank-3 Hysteria will deal
  $Base Damage \times (1 + Damage Mods) \times (1 + Elemental Mods) \times (1 + Strength Mods) =$
  $250 \times (1 + 1.2) \times (1 + 0.9) \times (1 + 0.3) = 1,358.5$ damage.
- The mods that can be equipped on and affect Valkyr Talons include:
  - damage (e.g., Steel Charge)
  - physical damage (e.g., Jagged Edge)
  - elemental damage (e.g., Shocking Touch)
  - faction (e.g., Smite Corpus)
  - critical chance and damage (e.g., True Steel and Organ Shatter)
  - Status chance (e.g., Melee Prowess and Vicious Frost)
  - attack speed (e.g., Fury and Berserker)
  - range (e.g., Primed Reach)
  - Condition Overload
  - Drifting Contact
  - Healing Return
  - Relentless Combination
  - Shattering Impact
    - While officially Set Mod bonuses do not affect Exalted Weapons (with the exception of the Sacrificial Mod Set), the Gladiator Mod Set can still apply if equipped on Melee or Robotic Weapons (i.e. Helios/Helios Prime's Deconstructor/ Deconstructor Prime), and not on the Exalted Weapon itself.
- Range mods do not affect the radius of slam attacks.
- Valkyr Talons can not be equipped with Melee Combo Counter Mods (except Drifting Contact), Acolyte Mods (e.g., Blood Rush), or Amalgam Mods (e.g. Amalgam Organ Shatter).
- Riven Mods are not generated for Valkyr Talons.
- The combo counter will reset when equipped with Xoris.
- Hysteria's combo counter decay is affected by Power Spike.
- Radial damage from slam attacks diminishes with distance, does not have a critical chance, is not affected by the Melee Combo Counter, and will cause enemies within range to suffer a knockdown.
- Ground finishers inflict 1600% of the total modified damage from normal attacks. Prompted finishers inflict 6400% of the total modified damage from normal attacks as True Damage.
  - The damage composition of a ground finisher is the same as a modified normal attack; however, Impact damage from ground finishers is multiplied by 125%.
  - The finisher multipliers for both attacks are affected by Finishing Touch.
- Each attack adds to the Melee Combo Counter; however, radial damage from slam attacks does not.
- Hysteria's innate lifesteal is calculated from the total damage of Valkyr's melee attacks after resistances are applied. Hysteria's lifesteal is also additive when combined with other sources of lifesteal
  - For example, a maxed Life Strike and a rank-3 Hysteria will yield
    $Base Lifesteal + Lifesteal Mods =$ $5% + 20% = 25%$ lifesteal on heavy hits.
  - Lifesteal is not affected by Ability Strength.
While active, Valkyr becomes immune to all damage and status effects.
- Status immunity includes crowd-controlling effects such as knockdowns, staggers, and Nauseous Crawler paralysis.
  - Certain attacks will still push Valkyr away, and shock waves will cause her to bounce into the air. However, these attacks will not force Valkyr to the ground.
  - Statuses that were already active when Hysteria was cast will not be removed. However, Valkyr will be immune to their damage regardless.
  - Valkyr is not immune to Commander teleportation, Regulator minimap disruption, Cryo Floors, Tar-Mutalist MOA slows, or Swarm-Mutalist MOA screen hazing.
Valkyr emits an aura with a radius of 5 meters around her while Hysteria is active, and 30% of the total damage she ignores is stored. If any enemies within this aura have line-of-sight of Valkyr when Hysteria is deactivated, Valkyr will be dealt 25% of all stored damage as Impact damage.
- The aura will continue to grow up to 20 meters and each kill reduces it by 1 meter. It cannot be reduced below 5 meters under any circumstances.
- Damage percentages are not affected by Ability Strength.
- Aura radius is not affected by Ability Range.
- Stored damage is calculated from the total damage Valkyr ignores before resistances are applied.
- The amount of stored damage can be monitored at the top right of the HUD under Hysteria's ability icon.
- Highlighted enemies become unmarked if Valkyr moves out of range, negating the damage taken when Hysteria expires.
- Since enemies need line-of-sight, invisibility prevents the damage.
After activation, a percentage counter will appear on the ability icon. The percentage increases to 100% over the course of 40 seconds.
- Hysteria consumes 2.5 energy per second at 0% while active. The cost will increase by an additional 2.5 until it caps out at 15 energy per second at 100%. Hysteria will remain active until either Valkyr's energy is depleted, or the ability is deactivated by casting it again (default 4 ).
  - Activation energy cost is affected by Ability Efficiency, and the energy drain is affected by Ability Efficiency and Ability Duration.
  - Valkyr cannot replenish energy using Squad Energy Restores, Rift Plane's energy regeneration, Energy Siphon, Zenurik's Energizing Dash, or Trinity's Energy Vampire while Hysteria is active. However, Energy Orbs, Orokin Void Death Orb energy restores, and/or Arcane Energize will still replenish energy normally.
  - Hysteria's energy drain is not converted into shields by Augur Mods.
Hysteria is affected by and can trigger Warframe and Exodia Arcanes.
While Hysteria is active, Valkyr can cast her other abilities and user her primary and secondary weapon. Switching weapons will disable Hysteria's effects, including making her vulnerable to damage again; it will also pause the energy cost increase but will continue to drain energy at the current rate.
Hysteria comes installed with its own unique stance. Additional combos will be unlocked as Hysteria increases in rank.
Has a cast time of 1 second, affected by Natural Talent.
- Despite being classified as its own weapon, Speed Holster will have no effect on casting speed. However, it will affect Hysteria's 'unequip' animation, played upon its deactivation.
Hysteria's attacks can damage enemies across the Rift Plane.

Main article: Valkyr Talons

Valkyr Talons are Valkyr and Valkyr Prime's signature Exalted Weapon that can only be used upon activating the ability Hysteria. The weapon exclusively uses the Hysteria stance.

Main article: Hysteria (Stance)

Hysteria is a unique Stance exclusive to Valkyr Talons that can only be acquired and used by activating Valkyr's fourth ability, Hysteria. This Stance overrides the Stance on any currently equipped melee weapon for as long as Hysteria remains active.

Main article: Hysterical Assault

Hysterical Assault is a Warframe Augment/Exilus mod for Valkyr that allows her to pounce onto enemies while in Hysteria by meleeing while aiming, dealing damage on contact. It also provides brief immunity when aiming a primary or secondary weapon.

Rank	Leap distance	Immunity duration when aiming	Cost
0	25m	0.5s	6
1	30m	0.5s	7
2	40m	0.5s	8
3	50m	0.5s	9

Main article: Enraged

Enraged is a Warframe Augment Mod for Valkyr's Hysteria that increases its damage and critical chance but fixes its duration to 15 seconds and adds a matching cooldown. The base energy cost is also increased to 50, while the energy drain over time is removed.

Rank	Damage & critical chance	Cost
0	+50%	6
1	+100%	7
2	+150%	8
3	+200%	9

There may be a dark red hue for the duration of Hysteria, making it difficult to see enemies. This is especially problematic if Infested Parasites are nearby.
- Turning 'Color Correction' off in Options > Display can alleviate this issue.
Her invulnerability can be taken advantage of in reviving teammates in exchange for consuming energy and not attacking enemies with her powerful claws.
- This can also be used to escape powerful opponents at the middle point of this ability. Allowing greater hit and run tactics.
It's preferable to use Steel Charge over Growing Power when modding for pure damage as the former adds more damage to Hysteria than the latter.
- Even with Steel Charge equipped, using Power Drift will still add more damage than Coaction Drift.
It's recommended to activate Melee Auto-targeting System in the options as Valkyr's awkward attack animations may miss a lot.
Players who suffer low FPS (Frames per second) may want to avoid attack speed boosts, such as Warcry, while using Hysteria. High attack speeds can result in a loss of DPS as melee attacks are "semi-automatic".
Charge Attacks in Hysteria open enemies to Finishers, allowing you to reliably use the damage boost without spending energy on her Paralysis ability.
- This finisher also knocks enemies down, allowing for a successive ground finisher for a quick burst of high damage.

Using Hysteria the moment you are downed by enemies will cause you to bug. Sometimes, you will only be able to use your actual melee weapon, but it will swing as though it is your claws; Other times you will be able to use your other weapons, and all while being invincible. You must wait until the effect ends for the bug to clear.
Attacks outside the vulnerability radius of Hysteria are still counted to the damage received in the Hysteria status, however these additional points do no effect at the end of the duration.
If only a melee weapon is equipped in the player's loadout, casting Hysteria while holding either a Codex or Synthesis Scanner will cause Hysteria's attacks to instead use the equipped melee's quick-attacks, while also rendering both combos and blocking unusable.
