Rising from the ocean depths, Hydroid harnesses the power of water to a devastating effect.

This is Hydroid, a deadly marauder from the deep.

Whether the seas or the stars, Tenno, Hydroid takes a foreboding command of the battlefield.

—Lotus

Release Date: April 10th, 2014

Wrathful and wayward as the seas he commands, the tidal plunderer Hydroid lurks beneath raging waves to plunge his foes into the abyssal depths. Unleashing salvos of cannon barrage and tentacled ocean horrors to rend foes asunder, Hydroid is reminiscent of the age of corsairs. Hydroid surfaced in Update 13.0 (2014-04-09).

Trivia

Hydroid is derived from the Greek "Hydro" meaning Water and the suffix "-oid" meaning 'Of similar form to', likely alluding to his ability to transform into water. It is also a life stage for species of the Hydrozoa class of jellyfish.
Hydroid was claimed by the Development Team to have been inspired from the theme of pirates and seems to resemble Davy Jones from The Pirates of the Caribbean movie franchise.
Hydroid is the first Warframe to use self-degrading Argon Crystal for construction in the Foundry.
Hydroid is one of the few Warframes that has visible "eye-spots" on his helmet.
Hydroid is one of two Warframes with powers capable of ignoring enemy armor, the other being Ash Ash's Blade Storm Blade Storm.
- Hydroid was the first Warframe to have True Damage True Damage, followed by Ash's revamped Blade Storm. Hydroid's True Damage also ignores shields.

“Market forces dictate that you need to evolve or die.”

Hydroid is Vaulted.

The Void Relics for this item have been removed from the drop tables at this time and are no longer farmable. Vaulted Void Relics in player inventories are not affected and can still be opened.

CODEX

Command the ocean's fury with this king of gold and silver. Featuring altered mod polarities for greater customization.

Fear... is the greatest of faith. While our immortal vines have left us distant from our baser selves, consider our subjects:

Those who gaze upon our cloud-swept towers, with simmering, violent envy, they hold still the old fears.

Depth and darkness... The windless embrace...

We will give to fear a form and yet none a vague hydra, a load monstrosity, surging from the unfathomable... reminding them who their gods are. Hydroid.

—Ballas

Release Date: August 29th, 2017

Vaultings

On June 28, 2019, it was announced that Hydroid Prime, alongside Ballistica Prime Ballistica Prime and Nami Skyla Prime Nami Skyla Prime, would enter the Prime Vault and be retired from the reward tables on July 6th, 2019. Any preexisting components or fully-built frames will remain as is.

Notes

Hydroid Prime, compared to Hydroid Hydroid:
- Higher Shields (175/525 vs. 125/375)
- Higher Armor (275 vs. 225)
- Higher Energy (150/225 vs. 125/188)
- Different Polarities ( vs. )
- Higher Mastery Rank required (5 vs. 0)
As a Prime Warframe, Hydroid Prime possesses a special passive ability where contact with an Orokin Void Death Orb will make them release an energy pulse that grants 250 Energy to all nearby allies. This effect can only occur once per Death Orb, and can occur even if the Death Orb has been previously destroyed.
Hydroid Prime's Tentacle Swarm Tentacle Swarm, Undertow Undertow and passive ability-spawned tentacles are no longer translucent. Instead, tentacles are opaque and and have a new organic texture that is affected by Hydroid Prime's Warframe Appearance colors.
- Energy color applies a coat of energy on the tentacle's model and alters the color of the numerous glow spots on the texture. This allows players to customize their tentacles to look similar to the older tentacle model prior to Update 21.4 (2017-08-10).
- Tentacle texture can return to default non-Prime translucency by equipping different skins (e.g. Hydroid Immortal Skin on Hydroid Prime)

Trivia

Hydroid Prime, along with Frost Prime Frost Prime, can achieve the third highest total shield value out of all Warframes at 3,195 by combining Redirection Redirection, Primed Vigor Primed Vigor, Augur Accord Augur Accord, and their maximum Overshields (+1200). Harrow Harrow currently holds the second highest possible shield value of 4,110, beaten only by Hildryn's 6555. These numbers can potentially be higher with other buffs that increase shield capacity (such as Shield Charger Shield Charger and Sequence).
Hydroid Prime was revealed at TennoCon 2017 alongside Excalibur Umbra Excalibur Umbra and Plains of Eidolon.
His Prime trailer was revealed at TennoCon 2020.
A fully built Hydroid Prime was given for watching TennoCon 2020 on WARFRAME's Twitch with a Twitch-linked account for 30 consecutive minutes, after 5:00 p.m. ET, on August 1st, 2020. It comes with a free Warframe slot and pre-installed Orokin Reactor.
- Due to thousands of players reporting missing Twitch drops, on August 6th, 2020 Hydroid Prime was distributed to all players if they were logged in to WARFRAME during TennoCon 2020, regardless if they watched the streams or not.^[1]

Passive

Hydroid Hydroid's melee slam attacks have a 50% chance to spawn a tentacle that lasts for 15 seconds. The tentacle senses nearby enemies within 5 meters to grab and thrash them, dealing 200 True Damage True damage per second bypassing shields and armor; captured enemies are released upon death or tentacle expiring. Up to 3 tentacles spawned by this passive may exist at once.

Passive values are not affected by mods.
Tentacle can capture multiple enemies at once, thrashing them at a slower animation speed to aid player aim.
Melee combos with slam hits have a chance to summon a tentacle.
Pilfering Swarm Pilfering Swarm applies to tentacles formed by this passive.

ENERGY: 25-50 KEY 1	Tempest Barrage Target an area and call down a barrage of liquid fury. Charge this attack to increase the lethality of the onslaught.	Strength:50 / 75 / 100 / 150 (Impact Damage Impact base damage) 100 / 150 / 200 / 300 (Impact Damage Impact charged damage)
		Duration:2 / 3 / 4 / 5 s (base) 4 / 6 / 8 / 10 s (charged)
		Range:5 m (explosion radius)
		Misc:∞ (cast range) 4/s (salvos per sec) 3 / 5 / 8 / 10 m (barrage radius)

Hydroid marks a targeted location for orbital bombardment over unrestricted range, calling forth an artillery barrage-like salvo of water missiles from above to strike the marked area 3 / 5 / 8 / 10 meters in radius for 2 / 3 / 4 / 5 seconds. Water missiles launch from above in a salvo of 4 per second, with each missile exploding on impact dealing 50 / 75 / 100 / 150 Impact Damage Impact damage and Knockdown enemies within a 5 meters explosion radius.
- Damage per missile is affected by Ability Strength.
- Damage does not bypass obstacles in the environment and does not diminish with distance.
- Duration is affected by Ability Duration.
- Explosion radius is affected by Ability Range.
- Casting speed and charging speed are affected by Natural Talent Natural Talent and Speed Drift Speed Drift.
- Cast range, salvos per second and barrage radius are not affected by mods.
- The barrage distinctly resembles a salvo of cannon-fire from an old warship. Like said salvo, it is not terribly accurate, but can threaten a wide area for several seconds and an enemy can be struck multiple times.
- Water missiles have a high chance to strike both grounded and airborne targets directly.
Tapping the button (default 1 ) initiates the ability cast immediately. Holding the button for up to 2.5 seconds allows Hydroid to charge Tempest Barrage for up to 200% damage per explosion and increased barrage duration, in exchange for double energy cost.
- Holding highlights the area around the aiming reticle in Hydroid's energy color, allowing free aim before releasing the hotkey to cast Tempest Barrage at the target location.
  - While charging, an audible flowing liquid sound plays.
- The barrage will be centered on the spot where the reticle is pointing up to the first solid object within view. This allows Tempest Barrage to be cast at distant locations as long as one has line of sight. Note that it tends to fall short if cast through a door or gateway.
- The barrage spot is decided upon releasing the cast; you can move the reticle freely before releasing the ability button.
- When cast on Snow Globe Snow Globe it will not be able to strike through it, but when cast within it will fall through it normally.
Ability Synergy: Can be cast during Undertow Undertow over unrestricted range. Submerged enemies receive damage and status effects from Tempest Barrage.
Tempest Barrage is a One-Handed Action that allows casting during movement, while midair, and on ziplines.
Can be recast while active to create multiple barrage instances.
Water missiles and their impact indicator circles are affected by Hydroid's chosen Warframe energy color.
Breaks containers and damages turrets/cameras.
Subsuming Hydroid to the Helminth will offer Tempest Barrage and its augments to be used by other Warframes.

Main article: Corroding Barrage

Corroding Barrage is a Warframe Augment Mod for Hydroid Hydroid where each projectile of Tempest Barrage Tempest Barrage has a percent chance of inflicting a Corrosive Damage Corrosive status effect.

Rank	Corrosive Damage Corrosive Status Chance	Cost
0	50%	6
1	65%	7
2	80%	8
3	100%	9

Tap 1 to quickly cast a short-lived barrage at the location you aim. Holding the hotkey will increase damage, duration and cost by up to 100%.
Mod for Ability Range to increase the explosion radius of each water missile, allowing more enemies to be damaged and knocked down inside and around the barrage area.
Cast multiple barrages in different directions to lock down chokepoints from incoming enemies.
Combo with Undertow Undertow and Tentacle Swarm Tentacle Swarm to inflict continuous damage and keep enemies from escaping.

ENERGY: 50 KEY 2	Tidal Surge Crash through enemies in a ferocious wall of water.	Strength:100 / 200 / 250 / 300 (Impact Damage Impact and Slash Damage Slash damage)
		Duration:20 / 25 / 27.5 / 30 m/s (speed)
		Range:3 / 4 / 5 / 6 m (striking radius)
		Misc:1 s (wave duration) 50% (Undertow travel distance)

Hydroid transforms into liquid and surges forward as a wave of water. While traveling in waveform, Hydroid becomes completely invulnerable to damage, as his speed increases to 20 / 25 / 27.5 / 30 meters per second over a duration of 1 second. Enemies within 3 / 4 / 5 / 6 meters of the wave are ragdolled and pulled along by the riptide, while dealt 100 / 200 / 250 / 300 Impact Damage Impact damage as the wave travels and 100 / 200 / 250 / 300 Slash Damage Slash damage as the wave breaks at the end of the duration.
- All damage is affected by Ability Strength. The Slash Damage Slash damage component diminishes with distance and is affected by body-part multipliers.
- Wave speed is affected by Ability Duration, while travel duration is not.
- Striking radius is affected by Ability Range.
Ability Synergy: While traveling in waveform, activating Undertow Undertow halts Hydroid at his current position and transitions directly into liquid form on impact with the ground.
- Enemies pulled by Tidal Surge will sink into Undertow as it forms.
- Likewise, deactivating Undertow while traveling in waveform halts Hydroid at his current position, causing him to emerge from the pool.
- Can be cast while in Undertow liquid form to travel half the normal distance.
  - Enemies previously drowning within Undertow will be pulled along by Tidal Surge.
  - Hydroid remains in liquid form during and after Tidal Surge as long as Undertow remains active.
Can be recast while active to renew the surge for continuous travel.

Main article: Tidal Impunity

Tidal Impunity is a Hydroid Hydroid Warframe Augment Mod for Tidal Surge Tidal Surge that allows Hydroid and all allies contacted by the ability to temporarily gain immunity to Status Effects, as well as removing already active ones.

Rank	Duration	Cost
0	8s	6
1	9s	7
2	10s	8
3	12s	9

It can be used to reach or pass certain areas of the map.

Sometimes when Hydroid emerges from the wave, his "fin" will be gone.

On PS4, if Hydroid is in the middle of a Tidal Surge when all players reach the extraction point, he will be permanently stuck in his dashing pose and simply clip into the drop ship during the "Mission Complete" mini-scene that plays during the loot screen.

ENERGY: 15 KEY 3	Undertow Become a water trap and drown unsuspecting enemies. Energy Drain: 6 s^-1 Grab Cost: 5 Meters per Energy: 0.2 m	Strength:10 / 15 / 20 / 25 (Impact Damage Impact dmg/sec) 1 / 1.5 / 1.7 / 2 % (dmg increase/sec)
		Duration:N/A
		Range:1.5 / 2.5 / 3 / 4 m (puddle size) 10 / 12 / 13 / 15 m (grab range)
		Misc:50% (Tidal Surge travel distance) 200% (Tentacle Swarm damage bonus)

Hydroid submerges into a pool of water with a 1.5 / 2.5 / 3 / 4 meters radius, becoming invulnerable to damage and untargetable by enemies. Enemies that wander onto the pool sink and disappear from sight, become suspended in a Knockdown state, and drown taking 10 / 15 / 20 / 25 base Impact Damage Impact damage per second; drowning enemies also receive 1% / 1.5% / 1.7% / 2% of their maximum health as Impact Damage Impact damage, which continuously stack every second while enemies remain submerged.
- Base damage and damage increase per second are affected by Ability Strength.
- Radius is affected by Ability Range.
  - Undertow uses the following expression when accounting for Ability Range: $Modified Range = Base Range \times Ability Range 0.5$
- Casting speed is affected by Natural Talent Natural Talent and Speed Drift Speed Drift.
- Damage increase per second applies to each individual enemy. The stacked damage for a single enemy resets to base damage when the submerged enemy exits the pool.
- Submerged enemies receive an additional +0.1% damage growth per second for each enemy in the pool.
  - Unaffected by Ability Strength
- The current number of submerged enemies trapped within Undertow is displayed on the ability icon.
- Allied players can shoot into Undertow to contribute 50% of their total damage from weapons and abilities, distributed evenly to all submerged enemies.
- Status Effects apply to all submerged enemies, with their effects and debuff timers paused until enemies exit Undertow.

While active, Hydroid can aim at an enemy target within 10 / 12 / 13 / 15 meters and press the primary attack key (default LMB ) to expend 5 energy, launching a water tendril from the pool, grabbing the target and pulling it into Undertow.
- Grab range is affected by Ability Range.
- Energy cost per grab is affected by Ability Efficiency.
- If the targeted enemy is unable to be pulled, the tendril will release it after a few seconds.
- Released bodies may make enemies suspicious and stop short of the pool. This will often result in them walking away from the puddle, requiring Hydroid to pull them in manually.

Undertow drains 6 energy per second, and will remain active so long as Hydroid has energy. Undertow will end if Hydroid runs out of energy, jumps (Space ), rolls (2x Shift ), or if deactivated by pressing the ability key again (default 3 ). Hydroid can slowly move while in Undertow by draining 1 energy point per 0.2 meters moved.
- Activation and travel energy costs are affected by Ability Efficiency, and the channeling energy cost is affected by both Ability Efficiency and Ability Duration.
- Energy Siphon Energy Siphon and other energy restoring effects are deactivated while Undertow is channeled. However, Arcane Energize Arcane Energize, Orokin Void Death Orb energy restores, Syndicate effects such as Blight and Entropy can still restore energy.
- If moving while in undertow you can sprint (hold Shift ) for faster movement speed. Mods that affect sprint speed also work with this.

Ability Synergy:
- Tempest Barrage Tempest Barrage can damage submerged enemies within Undertow. Corroding Barrage Corroding Barrage can also proc Corrosive Damage Corrosive on submerged enemies.
- Tidal Surge Tidal Surge allows Hydroid to remain submerged in Undertow and travel in waveform for half the normal distance.
  - Undertow will not drain additional energy when Hydroid moves via Tidal Surge.
  - Enemies previously submerged in Undertow will be pulled along by Tidal Surge.
- Tentacle Swarm Tentacle Swarm centers the kraken on Undertow and spawns tentacles inside the pool. Charged cast can extend tentacle spawn radius outside Undertow.
  - Tentacles will capture enemies when they emerge from Undertow.
  - Tentacle Swarm deals 200% damage when cast from Undertow.

Hydroid's Companion will also be submerged, regardless of distance from him. His companion will not become invulnerable and is susceptible to damage from explosions.
Enemy corpses will be released from Undertow when killed.
Cannot switch, fire, or reload weapons, perform parkour Maneuvers except jump and roll, nor collect Pickups while in liquid form.
Can be cast while in midair to enter liquid form. Undertow pool will form when Hydroid lands on the ground.

Aura effects from enemy Eximus will not apply to Hydroid while he is submerged but nearby Tenno will suffer from the effects of the Eximus unit's aura if they are in range.
- Energy Leech Eximus still will drain energy when in the pool, however.

When Hydroid is submerged, the game treats him as invisible to enemies. As such, any kills on unalerted enemies with undertow will count as a stealth kill.
- Also causes the Zenistar Zenistar to deal bonus stealth damage to enemies.
  - There is a bug related to this where a Zenistar built with blast will continue to deal bonus damage to some enemies even when Hydroid re-emerges from the puddle.

Submerged enemies cannot prevent Tenno from capturing an Interception point. This makes it incredibly efficient at completely locking down towers on Interception missions.

Main article: Curative Undertow

Curative Undertow is a Hydroid Warframe Augment Mod that allows Undertow Undertow to heal Hydroid Hydroid and his allies within range by a percentage of their max health every 1.5 seconds, draining additional energy for each ally in the pool.

Rank	Effect	Cost
0	15%	6
1	20%	7
2	25%	8
3	30%	9

Undertow will knockdown enemies within range when they sink into the puddle. Activating then deactivating Undertow allows you to set up Ground Finisher attacks with your melee weapon on nearby enemies.
If you see an enemy Eximus walk into the pool, deactivate Undertow and expose them to attacks, as their Auras will remain active while submerged.
- As Energy Leech Eximus are still able to steal energy from Hydroid while in the pool, it's ill advised to drag them in. It's safer to cast Tempest Barrage or Tentacle Swarm on their location when they are far away to avoid losing massive amounts of energy per second.
When running an Infested Defense (such as an uncontested Dark Sector or Orokin Derelict), stand near the cryopod or a walkway to the cryopod and activate Undertow. Once you've collected several enemies, deactivate Undertow and chain together Area of Effect skills such as Tempest Barrage Tempest Barrage and Tentacle Swarm Tentacle Swarm.
If you are under heavy fire, activate Undertow to regenerate your shields, as well as health depending on whether your squad has a member with the Rejuvenation Rejuvenation aura equipped.
Undertow is useful for gathering large numbers of enemies in one spot for another player to kill them once the ability has ended.
Undertow cannot be used to bypass corpus laser doors by itself.

At times a miniature Hydroid and his sentinel can be seen on the pool.

When this bug occurs enemies will begin throwing grenades at the player and will be able to injure the player.
This bug can also rarely occur on PS4, however instead of appearing tiny you will see Hydroid's head and shoulders clip through the floor at their normal size (only when moving).
If Battalyst and Manic Bombard do not die after 1 minute, they are freed from Undertow.

Some bosses, such as General Sargas Ruk can be submerged by Undertow, making them invulnerable to outside damage by other players.
Enemies see dead bodies that are killed and will often refuse to enter the pool. This requires the use of hydroid to manually pull them in.
A sentinel equipped with Vacuum Vacuum will still attempt to suck up loot while in the pool, which blocks the player's reticle and prevents them from targeting enemies to drag into the pool.
- This will slightly alleviate itself after staying in the pool for an extended period, as sentinels will "freeze up" and stop moving if the player idles for too long.
Cameras can be targeted, but cannot be tentacled in.
Downed Bursa will stay in undertow and count as alive there.

ENERGY: 50-100 KEY 4	Tentacle Swarm Tap to spawn watery tentacles from all nearby surfaces to wreak havoc. Charge to increase the number of tentacles and spawn area. Use while in Undertow to have the tentacles emerge from the pool.	Strength:75 / 150 / 225 / 300 (Magnetic Damage Magnetic contact damage) 50 / 100 / 150 / 200 (True Damage True capture damage per second)
		Duration:10 / 13 / 18 / 20 s
		Range:3 / 3 / 5 / 5 m (base radius) 9 / 9 / 15 / 15 m (charged radius)
		Misc:∞ (cast range) 4 / 6 / 8 / 10 (tentacles) 8 / 12 / 16 / 20 (charged tentacles) 200% (damage bonus from Undertow)

Hydroid summons a creature from the deep, causing 4 / 6 / 8 / 10 tentacles to emerge from all surfaces within a marked location 3 / 3 / 5 / 5 meters in radius, cast over unrestricted range. Tentacles prioritize spawning beneath enemies inside the radius, with each tentacle capturing their initial targets or throwing them upward, dealing a maximum of 75 / 150 / 225 / 300 Magnetic Damage Magnetic damage upon emerging, on first contact with enemies, and when submerging as the ability expires after 10 / 13 / 18 / 20 seconds. Captured enemies are incapacitated in a ragdoll state and stay attached to the flailing tentacles; bypassing Shields 50 / 100 / 150 / 200 True Damage True Damage will be dealt per second.
- Tentacle Magnetic damage and True damage per second are affected by Ability Strength, while number of active tentacles is not.
  - Magnetic damage calculation when accounting for Ability Strength is squared (e.g., with a maxed Intensify Intensify, the tentacles will deal a maximum of $300 \times 1.3^2 = 507$ Magnetic Damage Magnetic damage at rank 3).
- Magnetic Damage Magnetic damage is effective against Shielded and Proto Shields, but less effective against Alloy Armor.
- Magnetic Damage Magnetic status effect amplifies damage to the shields of the afflicted target by 100% and nullifies natural shield regeneration for 6 seconds.
- Spawn radius is affected by Ability Range.
- Duration is affected by Ability Duration.
- Casting speed and charging speed are affected by Natural Talent Natural Talent and Speed Drift Speed Drift.
- Tentacles detect and capture new enemy targets when they come into range.
- Tentacles can capture multiple enemies at once.
- Tentacles with captured enemies will flail their victims around slowly, allowing players to take aim and kill their targets.

Tapping the button (default 4 ) casts the ability immediately. Holding the button for up to 2.5 seconds charges Tentacle Swarm, increasing the number of tentacles spawned up to 8 / 12 / 16 / 20 and spawn radius up to 300%, in exchange for up to double energy cost.
- Tentacle Swarm's spawn area will be highlighted by Hydroid's energy color during the casting and charging animations.
- Spawn area indicator visibly grows in size as Tentacle Swarm is charged.
- While charging, an audible whale-like call from the Kraken plays.

Ability Synergy: Can be cast while in Undertow Undertow liquid form to center Tentacle Swarm on the pool.
- Quick cast causes all tentacles to spawn inside Undertow's radius, while charged cast extends the spawn radius outside of Undertow.
- Tentacle Magnetic Damage Magnetic damage and True damage per second deal 200% damage when cast from Undertow, including tentacles that spawn outside Undertow.

Casting Tentacle Swarm is a two-handed action that stops Hydroid's movement and other actions. Charging Tentacle Swarm is a two-handed upper body animation that allows player movement.
Can be recast while active; however, only one instance of Tentacle Swarm can be active at a time. Recasting will replace the previous instance.
Hydroid briefly summons the Kraken at the center of the spawn area as a visual effect. The Kraken emerges from a pool of water, then submerges slowly and disappears. Kraken is affected by Hydroid's chosen Warframe appearance and energy colors.
Tentacles appear as translucent water tendrils emerging from a small puddle of water. Tentacles emit splashes of water periodically, as well as a steam particle effect at their base which is affected by Hydroid's chosen Warframe energy color. However, when the ability is cast by Hydroid/Prime, the tentacles will be opaque and more organic in appearance.

Main article: Pilfering Swarm

Pilfering Swarm is a Hydroid Hydroid Warframe Augment Mod that grants Tentacle Swarm Tentacle Swarm a chance to yield additional loot from enemies killed while they're ensnared by the tentacles.
