Info

• Whispers from the Void infuse Xaku with untold power, 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. Xata's Whisper lasts for 20 / 30 / 30 / 35 seconds.
• 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.
  • The ability double dips on faction damage, and body part weaknesses.
  • 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  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, nor the ghostly energy form of the Eidolon Vomvalyst, nor the Thrax Centurion or Thrax Legatus enemies from the Zariman Ten Zero.
  • 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.

Info

• Breach through the Void to summon a mass of grasping tendrils, 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 stolen 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 ?%  Stagger chance to light units. If cast on a weaponless or disarmed enemy, a Void replica of Xaku's primary weapon or a Void orb in the absence of a primary, orbits Xaku instead.
  • 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.
  • The max number of stolen weapons is rounded down to the whole number multiple of the range modifier, and the base number; e.g. with 115% ability range, the number of stolen weapons is 6 × 115% = 6.9, which is rounded down to 6. An ability range of 130% would be 6 × 130% = 7.8, which rounds to 7. The max number of stolen guns normally achievable by this method is 16, achieved with an ability range of 267%, slightly below the normal max of 280%. If max range is increased beyond normal levels by some means, this number will increase accordingly.
  • Casting speed is affected by Casting Speed.
  • Heavy units such as Heavy Gunner are immune to the stagger effect.
  • 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.

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 speed is affected by Casting Speed.
  • 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:

• Distorting reality with Accuse, Xaku manifests a Void fissure at the targeted location on the aiming reticle over infinite 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.
  • 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 (e.g. Defense). 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.

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 6 / 8 / 10 / 12 meter radius, which weakens other enemies' maximum Shields and Armor by 20% / 30% / 40% / 50% while within range. Up to 2 Gazed targets may exist at once.

• Enemy armor and shields are fully removed at 200%  Ability Strength. With one  Corrosive Projection, armor will be fully stripped at 164% Ability Strength.
  • Shield strip removes a percentage of the current maximum value. Armor strip, however, is a percentage of an enemy's total.
• While invulnerable, the Gazed target is still susceptible to Status Effects, with exception of the inability to proc  Void status.
• Gaze defense reduction auras will stack with other defense reduction effects, but multiple Gaze auras do not stack with each other, whether from the same caster or from another Xaku in the squad.
• 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.
• If an enemy that has both shields and armor wanders into Gaze's aura, such as an Oxium Osprey, then shields will be prioritized over armor.

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.

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.

Discharging a torrent of Void energy, Xaku unleashes a ray of piercing light toward the aiming reticle with infinite body Punch Through that travels up to 25 / 30 / 35 / 40 meters away. Enemies struck directly or within a ? meters radius from the 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.

• Deny's Void damage benefits from  Ability Strength, number of  Grasp of Lohk's Void replicas, and  The Vast Untime's 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.
• 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 renders enemies 50% more vulnerable to Deny's beam 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.

Info

• Death and decay encroach as Xaku detonates themselves, 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 and suffer 50%  Void Damage Vulnerability and 10% / 15% / 20% / 25%  Slow for 10 / 15 / 20 / 25 seconds. For the same duration, Xaku's skeletal form is exposed, increasing 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. Xaku can reform their body and manually deactivate the ability by holding the ability key (default 4 ).
  • Slow is capped at 100%, achieved with 400%  Ability Strength.
  • Increased dodge chance is displayed next to the shield and health indicators as a buff icon with the chance percentage.
  • Casting speed is affected by Casting Speed.
  • Void damage from the blast does not reset Sentient damage resistances.
  • The blast can destroy Objects, which does not require line of sight.
• 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.
  • Enemies hit by The Vast Untime's explosion are  Void damage vulnerable to  Xata's Whisper,  Grasp of Lohk, and  The Lost's Deny.
• Can be recast while active in skeletal form by pressing the ability key again (default 4 ), causing Xaku to detonate again and affect new enemies in range, as well as refreshing ability duration to full. Note that there is a small window where the timers of Xaku's other abilties can run down before The Vast Untime is recast.
• 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 Armor Cosmetics and Syandana are hidden during the skeletal form. Regalia, Sigils, and Ephemera remain visible.
• Enemies affected by The Vast Untime's vulnerability and slow effects emit a Void energy cloud around their torso.
