CODEX

This master alchemist effortlessly commands the elemental forces.

Manipulating the laws of the physical realm, his prowess permeates the battlefield. This is Lavos, the transmuter, the elemental craftsman.

Lavos harnesses the secret of invention, Tenno. Experimentation is the beauty of science.

—Lotus

They say that Lavos often takes counsel from his serpents. One is his brutal advisor, the other his wise teacher. Both have their wisdom, and Javi still whispers to his beloved student.

Much like the snake, Lavos is easy to misjudge. The serpents that poison can also cure. He may have been a monster in his previous life, but he was able to achieve something that eluded the most powerful of the Orokin. He changed.

Moreover, he changed himself. Javi may have helped and instructed, but the will to change must have begun with Lavos.

Perhaps we all have that golden gleam coiled within us somewhere, ready to slither forth from its old skin. We must only beware that we do not condemn as devilish that which we do not yet understand.

—Drusus

Release Date: December 18, 2020

Concoct volatile brews of recombinant elements to dissolve, evaporate, and transmute hostile forces. Equalize the System through alchemical warfare as the eccentric scientist, Lavos, to dose his foes with serpentine venom and alter the state of combat conditions through his unorthodox experiments. Lavos's transmutation began in Update 29.6: Orphix Venom.

Lore

Main article: Leverian#Lavos

Lavos. The transmuter. Called by some, anachronistically, the alchemist.

Transmutation, you say? A superstitious process from long ago, in which deranged old men heated stinking substances over fires of dung, thinking they could make gold?

No. To the Orokin, it was a darkly potent, forbidden science. They were not squeamish nor moral, so what profound taboos must this art have violated?

No transmuter was more dreaded than Javi. The Crawling Serpent. The Abhorred. The Filth-Speaker.

The Orokin feared him so greatly that they whispered he might, somehow, survive even the Jade Light, just as a severed snake was once believed to grow a new head. So instead he was imprisoned, that his evil might be contained, if not quenched.

His jailer was a brute of a Warframe named Lavos.

—Drusus

Lavos served as a warden to the prison of Dabaoth-Kra on Venus containing an Archmedian named Javi, whose alchemy was feared by the Orokin as they believed it would allow the lower caste to rise up against them. During his imprisonment, Javi would draw seemingly demonic symbols and snakes in his cell, and was reportedly whispering to Lavos during his beatings.

Fearing that Javi would somehow survive the Jade Light, his sentence was overturned to cellular reversal to reduce him to biological pulp. After Lavos received the ceremonial garb to carry out the execution, he no longer beat the prisoners. Lavos realized that Javi's writings were not of demonic origin but of evolution and healing.

When the day of execution came, as Lavos raised his  Cedo shotgun, Javi whispered. In response, Lavos lowered his weapon and bowed before activating his power, liquidizing Javi's flesh. The Orokin jailers cheered before realizing in horror that Lavos was not executing the alchemist, but transmuting the remains; Javi would be reborn as a serpent on Lavos's arm, while a second serpent emerged from Lavos's own flesh as a symbol of change. The new student of alchemy proceeded to massacre the Orokin jailers with a  Vial Rush.

Not one survived the fall of Dabaoth-Kra save for a floor-washer named Bekran Zaft, who lived to tell the tale.

Notes

• When Lavos wields his signature  Cedo, a  Shotgun Ammo Mutation effect is applied.
• At max rank, Lavos has the second highest base armor of all Warframes, behind  Valkyr Prime. Even with Lavos at minimum rank, only  Valkyr and  Atlas Prime have higher armor.
• Lavos, along with  Hildryn, boasts the lowest base energy of all Warframes, having none at all.
  • However to utilize his passive ability (by collecting energy orbs), he still technically possess a hidden energy pool of 175, which automatically drains itself in 5 seconds. The energy pool is only visible when modding inside the Simulacrum.
  • Likewise his rank-up bonuses instead feature armor rather than an energy pool increase.
• Lavos is the first Warframe to modify Mod bonuses for himself, in his case Ability Duration affects his status effect durations while Ability Efficiency affects the cooldown reduction of  Transmutation Probe.
• Lavos is the second Warframe (after  Nidus) to gain additional armor with high rank. As with Nidus, the bonus armor that Lavos gets from levelling is not affected by armor-boosting Mods such as  Steel Fiber; they only calculate off of the original armor and the extra is added at the end.

Tips

• Lavos's lack of energy makes him an ideal Warframe to use in missions where energy regeneration would be severely hampered, such as in Nightmare Mode missions with the Energy Drain modifier, or Energy Reduction Modifiers in Sorties.
  • In Rathuum and The Index where Tenno start with no energy, Lavos can immediately utilize his abilities.
• Lavos's lack of energy for abilities means that he does not suffer from energy loss caused by energy drain attacks and abilities, such as from Parasitic Eximus units and Sensor Bars.
  • Conversely, due to his lack of energy, all energy interactions other than energy orbs provide no benefit for him, such as  Trinity's  Energy Vampire,  Energy Siphon,  Rage/ Hunter Adrenaline,  Quick Thinking/ Gladiator Finesse, Zenurik Focus, or  Arcane Energize.

Trivia

• Lavos is the 45th unique Warframe to be released.
• Lavos was conceptualized by Digital Extremes concept artist Nikita Leshakov, alluded to have sketched the first concept art during his lunch break.
• Lavos was first revealed during Tennocon 2020's Art of Warframe Panel alongside Wraithe. His name was announced in Home Devstream 7, and his abilities were finally revealed in Home Devstream 10.
• Lavos was featured in a fashion-frame showcase video made by [DE]Megan for reaching the final donation goal in the Quest to Conquer Cancer campaign.
• Lavos' visual design incorporates serpents wrapped around his arms and alchemical vials containing volatile mixtures that fuel his Warframe abilities.
  • Lavos' serpents are likely references to the Caduceus and Ouroboros. During idle animations, the serpents will perch their heads up from Lavos' arms, as well as slither and move around on his body.
  • Lavos' vials on his shoulders are separate attachments called Lavos Shoulder Guards that are customizable in his Appearance options.
  • His vials initially contained a silver liquid solution that resembles quicksilver, later adopting the Warframe's energy colours.
  • While in motion, his vials will have 'jiggle physics' and the liquid inside flows around. Liquid swishing sounds can be heard when Lavos is moving.
• Lavos' default helmet displays signs of acid burns on one side of the hat, as a memento of his previous experiments gone awry. This change was added during development to prevent the helmet from blocking the player's aiming camera.
  • This causes Lavos' design to be asymmetrical.
• According to [DE]Pablo, the name Lavos took inspiration from Antoine Lavoisier, a French chemist.
• "Lavos" is probably related to the Latin verb lavo, lavare "to wash", and may be a reference to the alchemical process of ablutio (washing or purification).
  • While not confirmed, Lavos' name may also be a reference to Davos, one incarnation of the Steel Serpent from Marvel Comics, fitting in with Lavos' snake theming.
• Lavos is the second Warframe that does not use energy for any abilities, after  Hildryn.

Passive

Valence Block

Purifying himself from all ailments,  Lavos cleanses all active negative Status Effects and gains status immunity for 10 seconds upon collecting an Energy or Universal Orb. Lavos can only collect a single Energy or Universal Orb every 5 seconds.

• Passive values is not affected by Mods.
• Buff duration is renewed to full upon collecting a new orb.
• Valence Block buff icon and timer are shown beside Lavos' shield and health indicators.
• While activated, three serpent-like energy particle effects encircle Lavos' body.
• If Lavos is injured with missing health, Universal Orbs are collectible to heal him with no cooldown period in between.
• When Lavos' Companion is equipped with  Synth Fiber, all nearby Health, Energy and Universal Orbs will be collected, bypassing Lavos' innate orb pickup cooldown entirely.

Special Casting

Stats and Modding

 Lavos has no energy capacity and his abilities do not use any resource to activate. Instead, each of his abilities are free to cast with a cooldown in between uses. The Ability Efficiency stat will instead affect the cooldown reduction effect from  Transmutation Probe.

• Mods which convert energy spent on abilities to shields, such as  Brief Respite or the Augur Mod Set, do not replenish shields.
• Because Lavos can still pick up energy orbs, mods or arcanes that benefit from picking up energy, such as  Equilibrium,  Energy Conversion, and  Arcane Energize, still function.
• Subsumed abilities injected into Lavos via the Helminth system will cost 0 energy, but instead incur a 10 second cooldown after cast and disable the elemental imbuement hold-function (see below) associated with the ability button.
  • On non-recastable abilities (e.g.  Roar), the cooldown begins after the ability's duration expires, unless modded with an augment that allows it to be recastable (e.g.  Piercing Roar).
  • On channeled abilities (e.g.  Gloom), they instead have a 12 second base duration.

The Ability Duration stat will also affect the Status Duration stat uniquely innate to Lavos, which extends or shortens the duration of all status effects created by Lavos using his weapons and abilities.

Lavos also possesses a Rank Up Bonus on his Armor stat, yielding +50% at Warframe Rank 30.

Elemental Imbuement

Experiment and unleash volatile mixtures of the deadly elements. Hold down one of the four ability buttons (default 1 ,2 ,3 ,4 ) to imbue a Primary Elemental damage type ( Toxin,  Cold,  Electricity, and  Heat respectively) into the mixing vial displayed above Lavos' ability icons. Imbuement has no cost nor cooldown between uses.

• Elemental imbuement is available by default to Lavos at Warframe Rank 0 without requiring his abilities to be fully unlocked.
• Primary Elements are shown in the four smaller diamond-shaped icons below the mixing vial. When an ability button is held down, its diamond icon is briefly highlighted until the element is mixed in.
• Combine with a different element to produce a Secondary Elemental damage type:  Blast (2 +4 ),  Corrosive (1 +3 ),  Gas (1 +4 ),  Magnetic (2 +3 ),  Radiation (3 +4 ), and  Viral (1 +2 ).
  • Inputs can be in any order, or the hotkeys can be held down together to instantly produce a Secondary Elemental damage type.
• The Imbued Primary or Secondary Element is shown in the vial with a colorcoded emblem and plays a unique sound effect upon mixing.
• With an element in the mixing vial, Lavos' next ability cast drains the vial to add the Primary or Secondary Elemental damage type, onto the chosen ability dealing an extra instance of damage and status proc.
  • The same Primary Elemental damage type can be imbued onto an ability that already inflicts that damage type (e.g.  Ophidian Bite imbued with  Toxin,  Vial Rush imbued with  Cold, etc) to double the damage and status proc.
  • Imbued Primary Elemental damage types do not merge with the ability's innate damage type.
  • Non-damaging status effects inflicted by all of Lavos' abilities ( Cold,  Blast,  Corrosive,  Magnetic,  Radiation, and  Viral) will proc 3 stacks in a single application of elemental status.
  • Lavos' mixing vial is only cleared of its elemental contents upon imbuing an ability.
  • Elements can be imbued even if Lavos cannot use the ability.
• Imbuement is only available from Lavos' original abilities, therefore a subsumed ability replacement from the Helminth system will disable the associated element on the ability button.
  • Imbuement also cannot be applied onto subsumed abilities.

	COOLDOWN: 8 s KEY 1	Ophidian Bite Lash out with a toxic serpentine strike, consuming the target to heal Lavos. Hold to imbue the next ability cast with  Toxin damage.	Strength:500 / 650 / 800 / 1,000 ( Toxin damage) 500 / 650 / 800 / 1,000 (imbued elemental damage) 7.5 / 10 / 12 / 15 % (damage to health conversion)
			Duration:N/A
			Range:10 m
			Misc:100° (cone angle) 100% (status chance) 100% (Melee Finisher vulnerability)

Info

• Lavos' serpents uncurl from his arms, lashing outward in a 100 degree cone spanning 10 meters in front of Lavos. Enemies in direct line of sight and in range receive a venomous bite that inflicts 500 / 650 / 800 / 1,000  Toxin and 500 / 650 / 800 / 1,000 Imbued Elemental damage and status effects, while briefly opening the affected enemies to melee finisher prompts (default X ); each enemy bitten also heals Lavos' Health pool for 7.5% / 10% / 12% / 15% of total damage dealt. Casting Ophidian Bite triggers a cooldown of 8 seconds before the ability can be recast.
  • Range is affected by Ability Range.
  • Toxin damage, imbued damage, and damage to health conversion are affected by Ability Strength.
  • Casting speed is affected by  Natural Talent and  Speed Drift.
  • Cone angle, status proc on hit, melee finisher prompt, and cooldown are not affected by mods.
  • Cooldown timer countdown is displayed on the ability icon.
• Ability Synergy:
  • Hold down the ability key (default 1 ) to add  Toxin damage to Lavos' mixing vial at no cost, as the Imbued Elemental damage type for his next ability cast.
    • Utilize  Toxin as key ingredient to produce  Corrosive,  Gas, or  Viral damage.
  •  Transmutation Probe reduces Ophidian Bite's active cooldown for each enemy it electrocuted.
  •  Toxin status effects inflicted on enemies by Ophidian Bite enhance  Catalyze's damage.
• Casting Ophidian Bite is a full-body animation that restricts movement and other actions. Casting from midair causes Lavos to dive toward the ground to complete the ability animation while standing on a surface.
• Lavos visually spreads his arms outward as his serpents stretch and converge toward the aiming reticle, while a forward converging energy force pushes outward and venom-like liquid particles outline the ability's conical area, before the serpents retract and coil themselves around Lavos' arms. Serpents and energy particles are affected by Lavos' Appearance colors.

	COOLDOWN: 5 s KEY 2	Vial Rush Dash forward, crashing through enemies and leaving an icy trail of broken vials. Hold to imbue the next ability cast with  Cold damage.	Strength:100 / 150 / 200 / 250 /s ( Cold damage per second) 100 / 150 / 200 / 250 /s (imbued elemental damage per second)
			Duration:4 / 6 / 7 / 8 s (residue duration)
			Range:30 m (charge distance) 14 / 17 / 20 / 24 (vial charges) 4 / 5 / 7 / 9 m (explosion radius)
			Misc:2 m (residue radius)  Cold and imbued elemental status proc per second 3 ( Cold status effect stacks per proc) 0.5 s (cancel delay)

Info

• Lavos charges forward in a sustained slide steerable with the left and right movement keys (default A , D ) for a distance of 30 meters, while his serpents rapidly throw out up to 14 / 17 / 20 / 24 vials from his waist belt. Thrown vials fall toward Lavos' left and right sides in an arcing trajectory, shattering on impact with solid surfaces leaving a trail behind him; shattered vials leave behind a pool of frozen residue at their impact zone, each lingering for 4 / 6 / 7 / 8 seconds and spanning a 2 meter radius that inflicts 100 / 150 / 200 / 250  Cold and 100 / 150 / 200 / 250 Imbued Elemental damage and status effects per second, to all enemies standing within the pools. At the end of his charge, Lavos emits an icy explosion spanning a 4 / 5 / 7 / 9 meter radius that inflicts a single instance of the  Cold and Imbued Elemental damage and status effects, while throwing out a ring of vials that shatter around his destination. Casting Vial Rush triggers a cooldown of 5 seconds at the end of Lavos' rush before he can charge again.
  • Charge distance, vial charges, and explosion radius are affected by Ability Range.
  • Residue duration is affected by Ability Duration.
  • Cold and imbued damage per second are affected by Ability Strength.
  • Residue radius, status proc per second, cooldown and casting speed are not affected by mods.
  • Explosion does not require enemies to be in direct line of sight to receive damage and status effects.
  • Cooldown timer countdown is shown on the ability icon after Lavos completes his charge.
  • While charging, Lavos is still land-bound and will drop down to the lowest terrain elevation in his path.
  • While charging, Lavos will attempt to slip pass obstacles in his path to continue his way. If held in place by an obstacle for at least two seconds, Vial Rush automatically stops, triggering the explosion and throwing the remaining vials out.
  • Due to being a non-damaging status effect, Vial Rush's  Cold status procs will stack 3 times per application as part of Lavos' passive mechanics.
  • Vials have travel time as arcing projectiles that are affected by projectile-altering abilities such as  Mag's  Magnetize.
• Halt Lavos in his tracks during his charge, triggering the explosion and releasing all remaining vials around him by pressing the jump key (default Spacebar ) to instantly stop; alternatively, press the ability key again (default 2 ) after Lavos dashed for at least 0.5 seconds to end Vial Rush early.
  • Cancel delay is not affected by mods.
• Ability Synergy:
  • Hold down the ability key (default 2 ) to add  Cold damage to Lavos' mixing vial at no cost, as the Imbued Elemental damage type for his next ability cast.
    • Utilize  Cold as key ingredient to produce  Blast,  Magnetic, or  Viral damage.
  •  Transmutation Probe reduces Vial Rush's active cooldown for each enemy it electrocuted. If enemies were electrocuted while Lavos is charging, the cooldown reduction carries over to Vial Rush's cooldown.
  •  Cold status effects inflicted on enemies by Vial Rush enhance  Catalyze's damage.
• Can be cast and interrupted while moving or in midair.
• Casting and interrupting Vial Rush are full-body animations that restrict movement and other actions.
• Nullifier Crewman and Isolator Bursa bubbles will interrupt Vial Rush if Lavos comes into contact with them.
  • Lavos will halt inside the bubble, triggering the icy explosion and releasing the remaining vials. Vials flung inside the nullification bubble will harmlessly disappear.
  • Vials touching the bubble from the outside will bounce away and land around it.
  • Residual pools fizzle away on contact with the bubble.
• Lavos visually assumes a sliding posture as he charges forward with energy trailing from his hands, while his serpents frantically flail in the air, rapidly grabbing and throwing vials from his waist belt. Upon stopping his charge, Lavos reels back as the icy explosion rapidly expands around him. Energy trails, vials, and residue pools are affected by Lavos' Appearance colors.
  • Residue pools resemble a cluster of floating frozen ice blocks with the broken vial at their center. When Vial Rush is imbued with a different element, unique energy particle effects emit from the pools representing the additional elemental damage type.
• Subsuming Lavos to the Helminth will offer Vial Rush and its augments to be used by other Warframes.
  • Subsumed Vial Rush includes the 0 energy cost, 5 second cooldown, as well as 3  Cold status proc stacks per application from the explosion and residue pools.
  • Subsumed Vial Rush does not include the hold-cast to imbue the next ability cast with  Cold damage.

	COOLDOWN: 10 s KEY 3	Transmutation Probe Launch a probe that converts Health and Energy Orbs into Universal Orbs that provide both, and ammo pickups into Universal Ammo Pickups. The probe shocks enemies in close proximity. Each electrocuted foe reduces other ability cooldowns by one and a half second. Hold to imbue the next ability cast with  Electricity damage.	Strength:100 / 150 / 200 / 250 /s ( Electricity damage per second) 100 / 150 / 200 / 250 /s (imbued elemental damage per second)
			Duration:N/A
			Range:3 / 4 / 5 / 6 m
			Efficiency:1.5 s (Cooldown Reduction per enemy shocked)
			Misc:15 m/s (probe speed) 3 s (probe duration)  Electricity and imbued elemental status proc per second 0.5 s (halt delay) 25 HP/EP (Universal Orb restore) 10 % (Universal Ammo restore)

Info

• Lavos launches an advanced alchemical apparatus toward the direction of the aiming reticle. The Transmutation Probe is an invulnerable floating device that travels at a speed of 15 meters per second, lasting for 3 seconds, as it emits a field of electrical currents spanning a 3 / 4 / 5 / 6 meter radius. Enemies within the electric field receive 100 / 150 / 200 / 250  Electricity and 100 / 150 / 200 / 250 Imbued Elemental damage and status effects per second; for each enemy electrocuted, 1.5 seconds is removed from the active cooldowns on Lavos' other abilities. Press the ability key again (default 3 ) after the ability has been active for at least 0.5 seconds, to hold the probe's position at its current location. Casting Transmutation Probe triggers a cooldown of 10 seconds when the active probe expires, before a new probe can be launched.
  • Radius is affected by Ability Range.
  • Electricity and imbued damage are affected by Ability Strength.
  • Cooldown reduction per enemy shocked is affected by Ability Efficiency.
  • Casting speed is affected by  Natural Talent and  Speed Drift.
  • Probe speed, probe duration, status procs per second, halt delay, and cooldown are not affected by mods.
  • Electric field does not require enemies to be in direct line of sight to apply damage and status effects.
  • The probe's duration timer is shown on the ability icon and must expire before the ability cooldown begins.
    • Therefore, Transmutation Probe cannot reduce its own cooldown timer.
  • Each enemy shocked may only reduce Lavos' other active ability cooldowns once per probe, not repeatedly while they stay in the field.
  • Although appearing as a floating object, the probe is affected by gravity and will drift down to the lowest available horizontal surface as it travels.
  • The probe collides with solid obstacles in the environment, stopping its movement prematurely.
  • Halting the probe by pressing the ability key again will stop the probe's movement permanently until it expires.
• Standard Pickups on the ground that pass through the probe's field, including Health Orbs, Energy Orbs, and Ammo Packs, are transmuted into special Universal variants; Universal Orb provides 25 Health and Energy points, while Universal Ammo Pack replenishes 10% of a weapon's ammo reserves for all equipped weapons.
  • Universal pickup restore values are not affected by mods.
  • Universal Orb is considered both a health orb and energy orb, allowing it to trigger on-pickup Arcanes such as  Arcane Energize and  Arcane Pulse, as well as activate mods such as  Health Conversion,  Energy Conversion, and  Equilibrium.
• Ability Synergy:
  • Hold down the ability key (default 3 ) to add  Electricity damage to Lavos' mixing vial at no cost, as the Imbued Elemental damage type for his next ability cast.
    • Utilize  Electricity as key ingredient to produce  Corrosive,  Magnetic, or  Radiation damage.
  • Transmutation Probe reduces all active cooldowns on Lavos' other abilities, including Helminth Subsumed abilities, for each enemy it electrocuted. If enemies were electrocuted while Lavos' other abilities are in use, but their cooldowns have not yet begun, the cooldown reduction is carried over to the cooldowns.
  •  Electricity status effects inflicted on enemies by Transmutation Probe enhance  Catalyze's damage.
• Can be cast and halted while moving or in midair. The probe will descend in a diagonal glide to the ground.
• Casting Transmutation Probe is an upper-body animation that allows movement while restricting other actions. Holding the probe's position does not play an animation on Lavos.
• Nullifier Crewman and Isolator Bursa bubbles are considered solid objects that block Transmutation Probe from traveling through them.
• Lavos visually summons the Transmutation Probe from his right hand as he throws the probe forward. The probe remains in perpetual motion rotating its upper half counterclockwise and lower half clockwise, while emitting two jets of gas for propulsion. Electrical currents forming the transmutation field encircle the probe in a similar pattern to electrons orbiting an atom. While in motion, the probe pushes a large spiraling energy force.
  • When a different element is imbued, the electrical currents adopt different appearances and energy particles representing the additional elemental damage type.
  • Transmutation Probe, gas jets, electrical currents, elemental particles, and energy force are affected by Lavos' Appearance colors.
• Universal Orb visually appears as a pulsating, rippling orb with a diluted blue outer layer enveloping a red inner core. Universal Ammo Pack shares the same model as those produced by  Protea's  Dispensary.

	COOLDOWN: 30 s KEY 4	Catalyze Catalyst Probes erupt from Lavos and douse combatants in a fiery gel. Damage is doubled for each element afflicting an enemy. Hold to imbue the next ability cast with  Heat damage.	Strength:1,000 / 1,500 / 1,750 / 2,000 ( Heat damage) 1,000 / 1,500 / 1,750 / 2,000 (imbued elemental damage)
			Duration:N/A
			Range:8.33 m/s (probe speed) 15 / 18 / 20 / 25 m (maximum distance)
			Misc:9 (number of probes) 3 s (travel time) 5 m (gel mist reach)  Heat and imbued elemental status proc on hit 100 % (damage increase per status effect)

Info

• Lavos materializes a satellite ring of 9 Catalyst Probes that fan out in all directions, traveling in a zigzag pattern at a speed of 8.33 meters per second for 3 seconds to reach a maximum distance of 15 / 18 / 20 / 25 meters before dissipating. Catalyst Probes are invulnerable and intangible flying devices that continuously spray a mist of highly flammable gel that extends 5 meters above and below the probes, to coat all enemies coming into contact. Enemies coated by the gel receive 1,000 / 1,500 / 1,750 / 2,000  Heat plus 1,000 / 1,500 / 1,750 / 2,000 Imbued Elemental damage and guaranteed status effects of both. Damage is further doubled for each unique elemental Status Effect active on an enemy before being coated by the gel. Casting Catalyze triggers a cooldown of 30 seconds when probes reach their maximum distance, before the ability can be recast.
  • Probe speed and maximum distance are affected by Ability Range.
  • Heat and imbued damage are affected by Ability Strength.
    • Damage is calculated by Damage = (Base Damage + Imbued Damage) × 2^{Unique Status Effects} × (1 + Strength Mods)
    • Proc damage is based on the portion of base/imbued damage. For example, imbuing  Heat does not double the damage for each heat proc, it merely applies two procs.
  • Casting speed is affected by  Natural Talent and  Speed Drift.
  • Number of probes, travel time, gel mist reach, status proc on hit, damage increase per status effect, and cooldown are not affected by mods.
  • Status effects of Physical damage types ( Impact,  Puncture, and  Slash), as well as  Void,  Lifted, and  Nukor's unique Microwave effect do not increase Catalyze's damage.
  • Catalyze's  Heat and Imbued Elemental status procs are applied after the damage increase per status effect calculation.
  • The remaining travel time for all probes is shown on the ability icon and must expire before the ability cooldown begins.
  • Although the gel mist visual effect appears several meters in front of the Catalyst Probes, enemies must be passed over by the probes to be affected by the ability.
  • Catalyst Probes only travel along the horizontal axis centered on Lavos' torso when the casting animation completes. Probes phase through all entities and obstacles in the environment as they travel.
• Ability Synergy:
  • Hold down the ability key (default 4 ) to add  Heat damage to Lavos' mixing vial at no cost, as the Imbued Elemental damage type for his next ability cast.
    • Utilize  Heat as key ingredient to produce  Blast,  Gas, or  Radiation damage.
  •  Transmutation Probe reduces Catalyze's active cooldown for each enemy it electrocuted. If enemies were electrocuted during Catalyst Probes' flight time, the cooldown reduction carries over to Catalyze's cooldown.
  • Each type of elemental status effects inflicted on enemies by weapons and abilities enhances Catalyze's damage.
• Can be cast while in midair.
• Casting Catalyze is a full-body animation that restricts movement and other actions. Catalyst Probes will spawn from Lavos at the end of the casting animation.
• Nullifier Crewman and Isolator Bursa bubbles do not dispel Catalyst Probes on contact, but will protect enemies from the gel sprays within the spheres.
• Lavos visually summons the Catalyst Probes from his right hand, raising his arm from front to back while forming a crescent ring above him, then reaching out collecting the probes into an Ayatan-like formation before launching the probes out in all directions. Catalyst Probes appear as horseshoe in shape with a gel vial attached to the inside of the ring. Probes emit gel blobs and two jets of gel spray from their sides, while pushing a wall of energy-like mist in front of them as they slither forward through the air.
  • Enemies hit by Catalyze emit a special fiery combustion visual effect as they catch on fire.
  • Enemies killed by Catalyze leave residual energy particles that represent heat and the imbued elemental damage type.
  • Catalyst Probes, gel blobs, sprays, mist, combustion, and elemental particles are affected by Lavos' Appearance colors.

Hotfix 30.0.5

Hotfix 29.10.7

• Fixed Lavos custom ability HUD overlapping Melee Combo Counter when dual wielding.

Hotfix 29.10.1

• Fixed a crash that could occur when Imbuing Lavos with Magnetic when he was already Imbued with Magnetic.

Update 29.10

• Ophidian Bite:
  • Increased the base Range from 8m to 10m.
    • What more is there to say? More whipping range! Beware the snake bites.
  • Increased Ophidian Bite’s downward vertical range.
    • Meaning there is now more distance between Lavos and the target underneath him where the cast will affect them, as per player feedback!
• Vial Rush: Vial Rush is now steerable!
  • Similarly to Gauss’ Mach Rush, once cast you can use the directional keys or your reticle to move Lavos around during his Vial Rush dash.
• Transmutation Probe:
  • Increased the cooldown reduction from 1s to 1.5s.
  • Made improvements to Transmutation Probe’s travel pathing.
    • There were issues with the probe getting stuck on environment obstacles, we have made changes to reduce the chances of that happening!
• Catalyze: Increased the travel speed of Catalyst Probes.
  • Catalyst Probes will now reach their max range positions quicker after cast.
• Added a half second delay to Vial Rush and Transmutation Probe before you can cancel the ability so that you don’t accidentally cancel them early.
• Fixed Lodestar Chest Plate, Heartwood Shoulder Plates, and the Arca Knee Guards clipping/tilting on Lavos.
• Fixed in-game Market UI showing that Lavos has 175 Energy, when in fact, he does not (since he does not use Energy). It will now show ‘0’ as intended.
• Fixed Lavos’ elemental imbue UI prompting “1 2 3 4” by default instead of controller bindings. Also adjusted the UI so that the imbue and button callouts are more easily readable.
• Fixed controllers not being able to toggle certain abilities off (like Lavos’ Vial Rush) without reactivating the ability menu.

Hotfix 29.6.4

• ‘Invert Tap/Hold Abilities’ option now lets you control the setting for each valid Warframe.
• Numerous Warframes Abilities new and old have been given the ‘Tap/Hold’ functionality to do varying actions. Feedback showed that having the option to Invert the ‘Tap/Hold’ across the board to all valid Warframes was not ideal, as some Ability default functionalities are preferred. Upon selecting the ‘Invert Tap/Hold Abilities’ in the Options menu, you'll be met with a new screen allowing you to pick and choose which valid Warframes this applies to!
• Fixed Infusing Lavos' Vial Rush to another Warframe not allowing it to inflict any Damage/Status.
