Xaku/Abilities

Passive

Shifting their pieces unpredictably, Xaku has a 25% chance to harmlessly phase through incoming enemy weapon attacks, while protected by a 25% damage reduction against area of effect damage. Passive dodge chance and area damage reduction both raise to 75% while The Vast Untime is activated.

• Passive values are not affected by Mods.
• Enemy attacks affected by the passive include hitscan, bullets, projectiles, melee attacks, and explosions.
• Evasion from mods such as  Agility Drift and Xaku's dodge chances are separate mechanics that do not stack.

	ENERGY: 25 KEY 1	Xata's Whisper Wield Void damage for all attacks from equipped weapons when activated.	Strength:17 / 23 / 23 / 26 % ( Void damage bonus)
			Duration:20 / 30 / 30 / 35 s
			Range:N/A
			Misc:1 (extra hit per damage instance) Sentient resistance reset (upon status proc)

Info

• Whispers from the Void infuse Xaku with untold power, by expending 25 energy to empower all equipped Weapons to inflict 1 extra hit per damage instance for 17% / 23% / 23% / 26% of total weapon damage as Void damage, which resets Sentient damage resistance upon Void status proc. Xata's Whisper lasts for 20 / 30 / 30 / 35 seconds.
  • Energy cost is affected by Ability Efficiency.
  • Damage bonus is affected by Ability Strength.
  • Duration is affected by Ability Duration.
  • Casting speed is affected by  Natural Talent and  Speed Drift.
  • Extra hit per damage instance and Sentient resistance reset on status proc are not affected by mods.
  • Xata's Whisper duration appears on the ability icon, as well as beside Xaku's shield and health indicators as a buff icon with the damage bonus and timer.
• Xata's Whisper Void damage is based on a percentage of the total weapon damage.
  • Damage bonus is a separate damage instance, and does not dilute weapon elements.
  • Affected by base, elemental, critical, and faction damage mods (e.g.  Serration,  Hornet Strike,  Pressure Point,  Convulsion,  Cleanse Grineer,  Vital Sense, etc)
    • Faction Damage Mods, after first applying to your weapon, will multiply the damage bonus a second time, effectively double-dipping.
  • Xata's Whisper can proc the Void Status Effect based on the weapon's total status chance.
    • The bullet attractor turns enemy projectiles towards themselves, effectively reflecting damage. This even applies to hit-scan weapons, which cannot exit the bubble.
  • The Void damage applies to most weapon hits, including  Acid Shells and  Concealed Explosives, but not  Nightwatch Napalm,  Bursting Mass or Pathocyst's maggots.
    • Since the damage bonus is not applied to the weapon directly, and only activates on-hit, it will not be absorbed into  Bursting Mass.
  • The Void damage bonus does not allow Xaku's weapons to damage Eidolon Shields of the Teralyst, Gantulyst and Hydrolyst.
  • Damage is affected by Ancient Disruptor auras and other enemies that reduce ability damage, unlike other weapon buffing skills.
• Ability Synergy:
  • Grasp of Lohk Void replicas and The Lost's sub-abilities do not benefit from the additional Void damage bonus of Xata's Whisper.
  • The Vast Untime renders enemies 50% more vulnerable to Void damage and pauses Xata's Whisper's duration timer while active.
• Can be recast while active to refresh the duration.
• Casting Xata's Whisper is an upper-body animation that allows movement while restricting other actions.
• On cast, Xaku's right shoulder and arm pieces visually detach then return to position. While active, Infested grey matter envelops their entire body as the Void veins pulse and glow with energy, while surrounded by a Void energy cloud near the torso.
• Subsuming Xaku to the Helminth will offer Xata's Whisper and its augments to be used by other Warframes.
  • When placed on Chroma, Mirage, Octavia, and Rhino, Subsumed Xata's Whisper can only replace Vex Armor, Eclipse, Amp, and Roar respectively.

Tips & Tricks

• When fighting against Sentients, it is recommended to use and mod weapons with high status chance, in order to efficiently reset their damage resistances.
• Recast the ability to refresh its duration or activate The Vast Untime to pause Xata's Whisper's duration timer, effectively prolonging the buff on Xaku as a semi-permanent damage bonus for all equipped weapons.

	ENERGY: 50 KEY 2	Grasp of Lohk Void Tendrils steal weapons from nearby enemies to use as your own floating, auto-targeting armament. Damage output increases based on enemy level. The number of weapons grabbed also determines the damage multiplier for The Lost: Deny's Void beam.	Strength:20 / 30 / 40 / 50 ( Void scaling damage)
			Duration:5 / 7 / 9 / 12 s
			Range:6 / 9 / 12 / 15 m (grab range) 5 / 6 / 7 / 8 m (target range) 3 / 4 / 5 / 6 (max targets)
			Misc:1.2/s (fire rate) ? % (stagger chance on hit) Damage is multiplied by enemy level

Info

• Breach through the Void to summon a mass of grasping tendrils, by expending 50 energy to Disarm up to 3 / 4 / 5 / 6 enemies within a radius of 6 / 9 / 12 / 15 meters from Xaku. Disarmed enemies resort to using melee weapons, whilst their ranged weapons transform into Void replicas that hover and follow Xaku for 5 / 7 / 9 / 12 seconds. Void replicas automatically target enemies within direct line of sight and a radius of 5 / 6 / 7 / 8 meters from Xaku, shooting a Void beam with a fire rate of 1.2 times per second, each inflicting 20 / 30 / 40 / 50 Void scaling damage with a ?% chance to stagger their targets. If cast on a weaponless or disarmed enemy, a Void replica of Xaku's primary weapon or a Void entity object in the absence of a primary, orbits Xaku instead.
  • Energy cost is affected by Ability Efficiency.
  • Damage is affected by Ability Strength and level of the targets disarmed by the ability, according to the following formula:
    • Total Void Damage = Void Damage × (1 + Ability Strength) × Enemy Level
    • At ability rank 3 with a maxed  Intensify equipped, with a Void replica created from a level 100 enemy, Xaku will deal 50 × (1 + 0.3) × 100 = 6,500 Void damage per attack.
  • Duration is affected by Ability Duration.
  • Grab range, target range, and max targets are affected by Ability Range.
  • Casting speed is affected by  Natural Talent and  Speed Drift.
  • Fire rate and stagger chance on hit are not affected by mods. Heavy units such as Heavy Gunner are resistant to the stagger effect entirely.
  • Xaku does not require line of sight to enemies to disarm them and steal their weapons. However, Void replicas themselves do require line of sight to target and fire at enemies, regardless if Xaku sees the targets or not.
  • Void damage from Void replicas do not reset Sentient damage resistance.
  • Void replicas will only target an enemy's torso when firing their Void beams.
  • Void replicas do not attack invulnerable enemy targets.
  • The number of active Void replicas is displayed as an icon beside Xaku's shield and health indicators.
• Ability Synergy:
  • Xata's Whisper does not grant additional Void damage to Void replicas.
  • Grasp of Lohk can disarm and steal the weapons of enemies affected by all sub-abilities of The Lost.
    • Void replicas will not attack enemies corrupted by Accuse, unless affected by Radiation status effect or other faction modifier abilities (e.g. Chaos)
    • Void replicas will not attack an enemy trapped by Gaze.
    • Void replicas amplify Deny's damage, based on the number of stolen weapons hovering around Xaku.
  • The Vast Untime renders enemies 50% more vulnerable to Void damage from Void replicas and pauses Grasp of Lohk's duration timer while active.
• Can be recast while active if under the max stolen weapons target cap. Recasting disarms new enemies and steals new Void replicas adding up to the cap, with each new gun under a separate full ability duration.
  • Cannot be recast while at max amount of stolen weapons.
  • Void replicas' visuals will gradually fade to black as they near their expiration point.
• Casting Grasp of Lohk is an upper-body animation that allows movement while restricting other actions.
• On cast, Xaku's chest, shoulder, arm, and thigh pieces visually detach then return to position. A vertically splitting Void breach appears directly in front of Xaku, as Void tendrils reach out in multiple directions, then retreat back into the quickly closing breach.
  • Void replicas appear in the shapes of the stolen weapons, blackened and pulsate with Void energy. Replicas hover on other side of the player camera to avoid obscuring vision during aim, occasionally twitch in a glitching-like fashion, and rotate themselves to face nearby enemies.
  • Void entity object resembles a dark sphere with swirling Void energy torrents encircling it.

Tips & Tricks

• Equip radar mods such as  Enemy Radar and  Animal Instinct to detect nearby enemies within range to disarm and steal their weapons, even through walls.
• By default, Void replicas will hover on the left side of Xaku. Toggle the player camera shoulder angle (default RShift ) to move them to the right side and vice-versa.
  • Due to each Void replica having its own line-of-sight, adjusting the side of the player camera shoulder angle allows replicas to target enemies that are otherwise not visible due to obstruction.
• Steal and maintain a large number of Void replicas to deal more damage, attack more targets more frequently, and increase the chance to stagger-lock incoming enemies.
• Recasting Grasp of Lohk yields numerous benefits:
  • Disarm new enemies or briefly stun disarmed enemies in range, forcing them to wield melee weapons and approach Xaku while entering the Void replicas' killzone.
  • Gather more Void replicas up to the modded maximum targets.
  • As enemy levels rise during a mission, newly stolen Void replicas will scale their damage based on the new enemy level of the disarmed targets. Stealing weapons from Eximus enemies will produce stronger Void replicas due to the level difference.
• Combo with The Lost's sub-abilities to further enhance Xaku's offensive and defensive capabilities:
  • Cast Accuse on a group of enemies then steal the corrupted's weapons, forcing them to become melee combatants to actively approach and distract enemies.
  • Cast Gaze on an enemy then standby near the target, allowing your Void replicas to quickly target and kill incoming enemies with their defenses reduced.
  • Cast Deny to deal increased damage with its Void beam, based on the number of Void replicas around you. Surviving enemies are lifted helplessly, allowing Xaku to close in with the Void replicas to eliminate them safely.
• Activate The Vast Untime to freeze Grasp of Lohk's duration timer, helping sustain your Void replicas for an extended period of time. Enemies hit by the Void blast are weakened to Void damage from your Void replicas.

ENERGY: 75 KEY 3

The Lost Cycle through a trio of lost Warframe powers. Accuse manifests a Void fissure to corrupt enemies into allies. Gaze grasps targets in Void tendrils that capture damage and inflict it when the target is released. Deny annihilates with a beam of Void energy, wiping Sentient resistances.

Strength:5 / 6 / 7 / 8 (max targets) Duration:4 / 8 / 12 / 16 s Range:5 / 7 / 9 / 11 m Misc:∞ (cast range) Strength:20 / 30 / 40 / 50 % (defense reduction) Duration:5 / 8 / 11 / 14 s Range:10 / 15 / 20 / 25 m (cast range) ? / ? / ? / 12 m (aura radius) Misc:?° (cone angle) 2 (max targets) 100 % (reduction cap) Strength:1,000 / 2,000 / 3,000 / 4,000 ( Void damage) Duration:5 / 8 / 11 / 14 s Range:? / ? / ? / 40 m Misc:? m (beam radius) 100 % (Sentient resistance reset on hit)

Info

• Heeding the voices within to harness their powers, Xaku selectively casts one of three abilities originating from the three fallen Warframes. Tapping the ability key freely cycles the selection wheel between the Accuse, Gaze, and Deny sub-abilities. Holding down the ability key (default 3 ) expends 75 energy to cast the selected power.
  • Casting energy cost is affected by Ability Efficiency.
  • Casting speed is affected by  Natural Talent and  Speed Drift.
  • Tap/hold cast can be inverted in the Settings menu.
  • The Lost's cycle selection wheel appears above Xaku's ability icons. Each ability's duration timer is displayed below their associated sub-ability icons in the wheel.
• Channel the Void to access their lost components' unique powers:

Accuse

• Distorting reality with Accuse, Xaku manifests a Void fissure at the targeted location on the aiming reticle over unrestricted range. Up to 5 / 6 / 7 / 8 enemies within 5 / 7 / 9 / 11 meters from the fissure become corrupted by Void energy for 4 / 8 / 12 / 16 seconds, stunning them in place then causing them to fight for Xaku and turn on their former allies.
  • Max targets is affected by Ability Strength.
  • Radius is affected by Ability Range.
  • Duration is affected by Ability Duration.
  • Cast range is not affected by mods.
  • Xaku does not require line of sight to enemies to corrupt them with Accuse.
  • While Accused enemies are briefly allied with Tenno, they can still be damaged by most sources and affected by some Warframe abilities.
    • Exceptions include Mesa's Peacemaker and Grasp of Lohk's floating weapons.
  • Accused enemies appear on the minimap as allied blue dots.
  • The number of active Accused units is displayed as an icon beside Xaku's shield and health indicators.
• Accused enemies do count toward mission progression. They must be slain or their ability duration ended to progress.
• Can be recast while active if under the max targets cap. Recasting on new enemies adds them to the existing number of Accused units up to the cap. Each new Accused unit has its own separate full ability duration.
  • Cannot be recast while at max targets count.
• Casting Accuse is a full-body animation that restricts movement and other actions.
• Xaku's shoulder and arm pieces visually detach and return to position, as Xaku reaches out with their right hand sending the right side pieces into the Void fissure forming at the targeted location. As the Void fissure forms, Void lightning strikes nearby enemies as the ability's area radius becomes briefly visible then fades with the breach's closing, while Xaku's pieces return to their positions on their body.
• Enemies affected by Accuse glow with an upward stream of Void energy that resembles the Vengeful Trickster Ephemera, as well as emitting a Void energy cloud around the shoulders.

Gaze

• Screeching in anguish with voices long lost, Xaku's Gaze freezes an enemy target within 10 / 15 / 20 / 25 meters and a ?° angle cone centered on the aiming reticle. Gazed target becomes entangled in Void tendrils, during which it is disabled, immobile, and invulnerable to damage for 5 / 8 / 11 / 14 seconds; while captive, the victim stores all damage prevented by its invulnerability and receives it in full when the ability expires. Gazed target also emits a defense reduction aura with a ? / ? / ? / 12 meter radius, which weakens other enemies' current maximum Shields and Armor by 20% / 30% / 40% / 50% while within range. Up to 2 Gazed targets may exist at once.
  • Range and aura radius are affected by Ability Range.
  • Duration is affected by Ability Duration.
  • Defense reduction is affected by Ability Strength and capped at 100%, achievable with a 100% increase in Ability Strength at max ability rank.
  • Cone angle and max targets are not affected by mods.
  • While invulnerable, the Gazed target is still susceptible to Status Effects, with exception of the inability to proc Void status.
  • Gaze defense reduction auras stack their effects with diminishing returns if overlapping on enemies, due to affecting the current amount of shields and armor (e.g. first Gaze reduces 50%, second Gaze reduces 50% of the new armor or shield total value)
  • Enemies regain their reduced shields and armor once they move outside of Gaze's aura.
  • If the enemy target dies before Gaze's entanglement fully takes effect, the casting energy cost is refunded to Xaku.
• Holding down the ability key (default 3 ) while aiming directly at a Gazed target releases the victim early, causing it to receive all accumulated damage prevented by its brief invulnerability.
  • Cannot be used if the required casting energy cost is not met.
• Gazed enemies do not count towards mission progression.
• Can be recast while active to entangle a new enemy, freeing the oldest affected enemy if cast at max number of targets.
• Casting Gaze is a full-body animation that restricts movement and other actions.
• Xaku's head, face, chest, shoulder and arm pieces visually detach, as Xaku screams into the air above while blob-like substances fly out from their torso. The enemy target is frozen in place as it becomes entangled in a mass of rapidly growing Void tendrils.
  • While affected, the enemy target emits a radial aura visual effect and emits a Void energy cloud around the shoulders.

Deny

• Discharging a torrent of Void energy, Xaku unleashes a ray of piercing light toward the aiming reticle that travels up to ? / ? / ? / 40 meters away. Enemies struck directly or within a ? meters radius from Deny's Void beam receive 1,000 / 2,000 / 3,000 / 4,000 Void damage, reset damage resistances if used against Sentient faction, and become suspended in aerial stasis for 5 / 8 / 11 / 14 seconds.
  • Range is affected by Ability Range.
  • Damage is affected by Ability Strength, number of Grasp of Lohk Void replicas, and The Vast Untime Void damage vulnerability.
  • Deny's Void damage benefits from Ability Strength, number of Void replicas, and Void damage vulnerability using the following expression:

    Total Void Damage = Void Damage × (1 + Ability Strength) × (Number of Void Replicas + 1) × Void Damage Vulnerability

    • At ability rank 3 with a maxed  Intensify equipped, stolen 6 Void replicas, against an enemy affected by The Vast Untime, Xaku will deal 4,000 × (1 + 0.3) × (6 + 1) × 1.5 = 54,600 Void damage.
    • Deny's damage can be further amplified by Enemy Body Parts multipliers.
  • Duration is affected by Ability Duration.
  • Deny's Void beam possesses infinite Punch Through against enemy bodies, but can be obstructed by solid obstacles.
  • Beam radius and Sentient resistance reset on hit are not affected by mods.
  • Enemies with selective crowd control effect immunity such as the Battalyst and Conculyst are unaffected by Deny's aerial stasis.
• Can be recast while active to strike new targets, or damage and refresh all effects on already affected enemies.
• Casting Deny is an upper-body animation that allows reticle repositioning and movement, while restricting other actions.
• Xaku's shoulder and arm pieces visually shiver then detach to hover above Xaku, as a beam of Void energy travels forward from Xaku's left hand, after which the pieces return to their positions.
• Enemies affected by Deny are suspended in the air by an upward stream of Void energy that resembles the Lifted status effect.

---

• Ability Synergy:
  • Xata's Whisper does not grant additional Void damage to The Lost's sub-abilities.
  • Grasp of Lohk can disarm and steal the weapons of enemies affected by all sub-abilities of The Lost.
    • Void replicas will not attack enemies corrupted by Accuse, unless affected by Radiation status effect or other faction modifier abilities (e.g. Chaos)
    • Void replicas will not attack an enemy trapped by Gaze.
    • Void replicas amplify Deny's damage, based on the number of stolen weapons hovering around Xaku.
  • The Lost's sub-abilities interact with each other in various ways:
    • Accuse can corrupt enemies into allies while they are lifted by Deny. However, it cannot corrupt a Gazed enemy target. Accused units will attack a Gazed enemy target, storing damage to inflict to the victim once released from the Void tendrils.
    • Gaze may be cast on an enemy affected by either Accuse or Deny. Gaze reduces the defenses of Accused units in range. Gazing an Accused unit creates an invulnerable decoy that draws enemy aggro until Accuse expires.
    • Deny does not affect Accused units, but will contribute damage to Gazed enemy targets.
  • The Vast Untime affects enemies crippled by all sub-abilities of The Lost and pauses all sub-abilities' ability duration timers while active.
• Each active sub-ability is a separate instance from Xaku. As such, the ability nullifying effects of special enemies (e.g. Nullifier Crewman) will not dispel The Lost's sub-abilities if only Xaku is affected.

Tips & Tricks

• Cast Accuse on a nearby surface or the ground below you to quickly corrupt surrounding enemies to help fight alongside you, or cast on a group of enemies off in the distance to create a distraction when faced with ranged threats.
• Accused enemies are allied units to the Tenno, therefore their special auras (such as those of Shield Osprey, Ancient Healer, Eximus, etc) or abilities will be used to briefly benefit you and your team.
• Cast Accuse on or near a mission objective to enlist the enemy to defend them for you.
• Cast Gaze on up to two enemies to completely disable them for the duration, while emitting an aura that reduces the defenses of other enemies in range.
  • All damage prevented by the Gazed target's invulnerability will be dealt in full when the ability ends.
  • Gazed targets do not halt mission progression such as Defense waves, allowing your defense reduction auras to persist in an area until you release the targets.
  • Gazed targets are still susceptible to status effects. Inflict Radiation procs to create an invulnerable distraction for nearby enemies.
  • Cast on enemies in different locations to encompass a larger area with the defense reduction auras, or close to each other to stack the defense reduction on enemies within the overlapping auras if the modded amount is below 100% defense strip.
• Gaze is cast within a cone centered on the aiming reticle. The closest enemy near the sides of the reticle will be automatically targeted by the ability.
• Cast Deny against enemies packed in a tight line to maximize its effect.
• Deny's damage is greatly amplified by the number of stolen weapons from Grasp of Lohk. Steal and maintain a large amount of weapons to deal devastating damage with Deny's Void beam.
• Enemies lifted by Deny are made easy targets for headshots from your weapons.
• Activate The Vast Untime to freeze all sub-abilities' duration timers. Accused enemies will remain on your side, Gazed targets stay trapped and emit their auras, and Denied enemies stay lifted airborne for an extended period of time. Strike enemies hit by the Void blast with Deny's Void beam to deal increased damage.

	ENERGY: 100 KEY 4	The Vast Untime Temporarily shed the outer pieces of Xaku in a destructive blast, then stalk the battlefield in a new, swifter skeletal form. Enemies damaged by the body shrapnel are rendered weaker to Void damage. Xaku's other active abilities' duration is frozen in time and resumes once The Vast Untime expires.	Strength:600 / 800 / 1,000 / 1,200 ( Void damage) 10 / 15 / 20 / 25 % (slow)
			Duration:10 / 15 / 20 / 25 s
			Range:10 / 15 / 20 / 25 m
			Misc:-50% ( Void damage vulnerability) 100 % (slow cap) 75 % (dodge chance and area damage reduction) +20% (move speed bonus) Ability duration paused

Info

• Death and decay encroach as Xaku detonates themselves, by expending 100 energy to explosively fragment their body parts outward. Enemies within direct line of sight and 10 / 15 / 20 / 25 meters of Xaku receive 600 / 800 / 1,000 / 1,200 Void damage from the blast; affected enemies also suffer 50% Void damage vulnerability and 10% / 15% / 20% / 25% reduced action speed while the ability remains active.
  • Activation cost is affected by Ability Efficiency.
  • Damage and slow are affected by Ability Strength. Slow is capped at 100%.
  • Range is affected by Ability Range.
  • Casting speed is affected by  Natural Talent and  Speed Drift.
  • Void damage vulnerability is not affected by mods.
  • Void damage from the blast does not reset Sentient damage resistances.
  • Destructible Objects within the blast radius are always damaged regardless of line of sight from Xaku.
• After detonation, Xaku exposes their skeletal form for 10 / 15 / 20 / 25 seconds or until manual deactivation by pressing the ability key again (default 4 ) to reform their body. While in their skeletal form, Xaku increases their passive ability's dodge chance and area damage reduction to 75%, grants themselves a 20% movement speed bonus, and completely pauses the duration timers of Xaku's other abilities.
  • Duration is affected by Ability Duration.
  • Dodge chance and area damage reduction, move speed bonus, ability duration pause are not affected by mods.
  • Xaku may still fight with their weapons, cast abilities, and perform parkour Maneuvers normally while in skeletal form.
  • Dodge chance is displayed next to the shield and health indicators as a buff icon with the chance percentage.
• Ability Synergy:
  • The Vast Untime pauses the ability duration timers of Xaku's other abilities, including both currently active and newly cast abilities while in skeletal form.
    • Only abilities belonging to Xaku originally are affected by the timer pause, whereas subsumed abilities via the Helminth system are not affected.
  • Xata's Whisper infuses Xaku's equipped weapons with additional Void damage, further amplified by The Vast Untime's Void damage vulnerability on enemies.
  • Enemies weakened by The Vast Untime receive more damage from Grasp of Lohk's Void replicas.
  • Enemies crippled by The Lost's sub-abilities can be affected by The Vast Untime.
• Activating The Vast Untime is a full-body animation that restricts movement and other actions, while deactivation is near-instantaneous.
• Xaku crouches in place, visually detaching their body pieces and suspending them in the air with Void energy tethers. Xaku then reels back, surging into the air, while most of their pieces scatter outward in an expanding Void energy blast. Xaku's skeletal form retains some body pieces for bare minimal structural support. Reforming the body pieces on Xaku causes them to quickly regrow on the skeleton.
• Xaku's Appearance attachments and Syandana are hidden during skeletal form. Regalia and sigils remain visible.
• Enemies affected by The Vast Untime's vulnerability and slow effects emit a Void energy cloud around their torso.
