Battalysts are Sentient combat drones. Capable of firing explosive projectiles and unleashing large clusters of omnidirectional lasers, Battalysts specialize in ranged combat. They have the unique ability to "adapt" to their enemy's attacks and gain resistances to damage types, facilitating the need to use multiple damage types in order to take them down.

They are first encountered in The Second Dream quest. They can then be encountered on the Orokin Moon tileset on Lua, spawning in pairs after an Oculyst scans a Tenno at the Orokin Moon tileset. They have also attracted the interest of the Corpus and can be very rarely encountered in Orb Vallis's Enrichment Lab, as well as in the Corpus Gas City tileset on Jupiter within the secret laboratories in test tubes and during the last phase of the Ropalolyst fight. They can mainly be found in Murex ships in Veil Proxima, where they dwell together with other Sentient unities.

Damage Adaptation[]

This section is transcluded from Sentient § Damage Adaptation. To change it, please edit the transcluded page.

As a Sentient, Battalysts have the ability to adapt up to 4 damage types from attacks: a Sentient's health is gated such that upon its hit points falling below a fixed percentage, it will grant resistance to the damage type it has received the most. The Sentient will adapt to damage once per health gate, at the percentages listed below:

  • First gate: 25% Health lost.
  • Second gate: 45% Health lost.
  • Third gate: 65% Health lost.
  • Fourth gate: 80% Health lost.

Subsequent adaptation will be done in descending order of damage proportion for each health gate. A single Sentient can adapt against a maximum of 4 damage types even if another Sentient transfers their adaptation, and Sentients will still receive full damage from any damage that exceeds their health gate before adapting.

On adapting to a damage type, the color of the glowing core on their chest changes to the corresponding damage type they recently adapted to, along with displaying the icon of said damage type below their health gauge.

The adaptation decreases in effectiveness the more damage types it resists.

  • For the first adaptation, the Battalysts will resist the damage type by 90%.
  • For the second adaptation, the Battalysts will resist the damage type by 80%.
  • For the third adaptation, the Battalysts will resist the damage type by 75%.
  • For the fourth adaptation, the Battalysts will resist the damage type by 70%.

Using the Operator's Void Beam, Excalibur UmbraIcon272 Excalibur Umbra's RadialHowl130xWhite Radial Howl, a rank 40 Paracesis Paracesis, Shedu Shedu's pulse on expending all ammo, or XakuIcon272 Xaku's Xata'sWhisper130xWhite Xata's Whisper will remove and reset all their acquired damage resistances. Sentients can still regain their resistances, however, the aforementioned abilities and weapons will always be able to remove them.

The Battalysts also receive another 40% resistance to the damage type at each adaptation, which stacks multiplicatively with the previously listed ones. These resistances cannot be removed by any of the methods listed above.

The damage gating also prevents Battalysts from being killed in one shot, as the maximum percentage of health removable in one instance is:

  • 25% at full health
  • 20% between 75% & 55% max HP
  • 20% between 55% & 35% of max HP
  • 15% between 35% & 20%, after which there is no limit and the Battalysts will take damage normally at every instance

A fledgling Battalyst deployed before it had a chance to fully develop.
  • Unlike the fully grown version, Tyro Battalysts do not benefit from Sentient Damage Adaptation.


  • Similar to their damage adaptation, they are also capable of adapting to debuff-based Warframe abilities such as NovaIcon272 Nova's MolecularPrime130xWhite Molecular Prime, with each subsequent use reducing the duration linearly by 33%, down to 5%.
  • The Battalyst's main method of attack is to fire explosive DmgTauSmall64 Tau based orbs with their tuning fork-like arms, dealing heavy damage.
  • Battalysts can release a blue orb that unleashes omnidirectional laser beams that deal heavy DmgTauSmall64 Tau damage, similar to Mirage's Prism. Small but dangerous explosions will occur around the point of contact with the lasers and the ground.
  • Sometimes, after adapting to an attack, Battalysts will release several bursts of wavelight that will damage shields, but will not harm health in a similar manner to Laser Barrier. Range: 15m radius centered on the Battalyst.
  • When near other Sentients, they can use their own version of Link130xWhite Link amongst themselves which splits the damage one takes equaly among the rest. Any damage adaptations that the host Sentient develops while linked will also be transferred over to the Sentient recipients.
    • If 2 sentients are linked, each will take 50% damage, if 3 are linked, each will take 33%, and so on.
  • The Battalyst's arms can be removed by shooting them, or with LokiIcon272 Loki's RadialDisarm130xWhite Radial Disarm. It is possible to remove both of their arms rendering them unable to attack normally, though this does not bar them from using their prism attack.
  • They are immune to levitating conditions such as WellOfLife130xWhite Well of Life and ragdoll conditions such as Pull130xWhite Pull.
  • Battalysts can use both of their arms to focus individually on multiple targets while using their primary attack.


  • Their weakpoint is the head. Ammunition will pass through their core and their chest.
  • Balanced damage-type weapons or channeled abilities with equal DmgImpactSmall64 Impact, DmgPunctureSmall64 Puncture and DmgSlashSmall64 Slash such as Burston Burston and ExaltedBlade130xWhite Exalted Blade may prove to be effective as these type of weapons/ability suffer the least damage loss per adaptation.
    • Weapons that deal high damage per hit like sniper rifles are more effective than high fire rate weapons that deal less damage per hit like automatic rifles, as the former can deal more damage beyond a Sentient's health gate, allowing more damage to be dealt with a particular damage type before the Sentient adapts.
  • As with the Conculyst, their arms can be removed by shooting them. It's possible to remove both their arms, leaving them unable to attack normally, but still able to use their special attack.
  • A NyxIcon272 Nyx with Mod TT 20px Assimilate can attack with ease, as the ability renders her immune to damage and procs while simultaneously allowing her to use her weapons.
  • ZephyrIcon272 Zephyr's Turbulence130xWhite Turbulence ability is capable of redirecting Battalyst's primary attack projectiles away from her, though it does not protect from AoE damage if a projectile hits next to her without entering the ability's range.
  • Be wary when using debuff abilities on this unit as each subsequent use will render them less and less effective. Avoid spamming certain abilities (such as RhinoStomp130xWhite Rhino Stomp) as it will raise their resistance to the debuff even if it is still in effect.
  • The Battalyst is immobile when it uses its Prism attack. If you can get above it or directly below it, it is possible to fire on a Battalyst during this time.
  • Their primary attack is inaccurate at a large distance. Use this to your advantage.
  • Due to their health not having any weakness or resistances to any damage type, weapons modded with full corrosive is most effective, as it will deal bonus damage to their ferrite armor which is weak to corrosive. It will not however, remove any of their armor.
    • Despite their immunity to Corrosive procs, a MagIcon272 Mag's Polarize130xWhite Polarize should suffice as a substitute to stripping armor.
  • If Second Dream quest has been completed, using transcendence, provided it finished charging, can quickly and easily dispatch Battlysts, trivializing the fight.
  • After finishing The War Within quest, using the Operator makes the fight much easier as the Void Beam cannot be adapted to and removes all of the damage adaptations the drone gained during the battle. Amps also makes fights against Battalysts significantly easier by providing additional firepower.

Patch History[]

Hotfix 32.2.4 (2022-12-07)

  • Fixed the Battalyst’s laser cluster ability not canceling after being ragdolled.

Update 30.7 (2021-09-08)

  • Changed the timing of the Sentient’s damage pulse & weapon reattach to occur at a specific time within the animation rather than at the end.
    • Previously, destroying both arms on Sentients would cause them to drop weapons. Sentients no longer drop anything when arms are destroyed but will instead regenerate them. This regeneration causes a damage pulse that has been modified to occur during the animation rather than at the end.
  • (Undocumented) No longer drop their health and energy restoring cores.
  • (Undocumented) No longer immune against status effects.

Hotfix 30.3.5 (2021-06-10)

  • Fixed Tyro Battalyst's disarm behavior; they don't actually support this so it would generate a script error in a variety of cases (ie Loki’s Radial Disarm, Xaku’s Grasp of Lokh, etc).

Hotfix 30.0.7 (2021-04-22)

  • Fixed script errors that could occur if you killed a Battalyst mid-disco.

Update 30.0 (2021-04-13)

  • Fixed script error related to the Sentient omnidirectional laser attack.

Hotfix 27.3.10 (2020-04-08)

  • Fixed Sentient Battalyst laser party ability not respecting physical Shield abilities, such as Frost’s Snowglobe and Atlas’ Tectonics, and instead going through the barriers to injure players.

Update 26.0 (2019-10-31)

  • (Undocumented) Can now spawn outside of Lua on Mobile Defense missions.

Update 23.0 (2018-06-15)

  • Slightly reduced the Battalyst's projectile damage.
  • Stunning or knocking down Conculysts during their whirlwind ability and Battalysts during their omnidirectional laser ability now cancels the ability.

Update 22.13 (2018-02-15)

  • Battalysts and Decaying Battalysts will now drop either an Exceptional (25%) or Intact (75%) Sentient Core.
