A lost soul. Part energy, part physical shell, these Sentient remnants seem to have a symbiotic relationship with the much larger Eidolons.

Eidolon Vomvalysts are spectral Sentient creatures firstly found roaming in the Plains of Eidolon at night. Another Vomvalyst variant, simply called "Vomvalyst", can be encountered on Veil Proxima inside of Murex ships, spawning from unique pedestals, similar to Immunodes. They possess 2 forms: a default physical form and a ghostly energy form to which they switch when they have taken too much damage.


  • Vomvalysts have two stages:
    • The physical form takes damage like any normal enemy. In this form they attack by launching pairs of semi-guided energy projectiles at enemies, which deal a considerable amount of damage
    • After their health has been reduced to zero, they will turn into their energy form and will only take damage from the Operator'sDmgVoidSmall64.png Void energy attacks. Energy-form Vomvalysts will attack by performing a charged dash towards any nearby enemies, similar to RevenantIcon272.png Revenant's Reave130xDark.png Reave. If their spectral form is not killed after a short duration, they will eventually regain their physical form.
  • Both forms possess 50% damage reduction.
  • On Plains of Eidolon, once they are destroyed, energy-form Vomvalysts drop a guaranteed energy sphere marked with a blue beacon, which can be picked up by Warframes and Operators and delivered to Eidolon Lures to charge them. These energy charges dissipate after a short time, however.
    • Alternatively, Eidolon Vomvalysts in their energy form can be directly absorbed by an Eidolon Lure if they enter its effective range.
  • Eidolon Vomvalysts spawn in pairs, unless spawned by a Eidolon Teralyst.


  • Vomvalysts have a chance to drop the Shard Black Pigment in packs of ten.
  • A variant of Vomvalyst appears as Interference Drones in every mission during Rising Tide quest.
    • However, this particular variant has no energy form and thus can be completely killed with conventional weapons.
      • Anu Mantalysts boarding a Railjack during a Murex Raid can deploy Anu Interference Drones, that disable turrets and engines until they are destroyed. Even these variants have no Spectral form.
  • Currently only the Eidolon variant has a Codex entry.


  • A good place to farm Eidolon Vomvalysts is along the eastern force-field boundary of the Plains of Eidolon, pairs of them will spawn every 40m or so right next to the force-field.
  • Along with Intact Sentient Cores, Eidolon Vomvalysts will also drop a glowing blue orb, which will charge the Warframe or the Operator with blue energy when picked up. The affected Warframe or Operator can then move near a friendly Eidolon Lure, transferring the energy to the Lure to charge it. Only one orb can be active per Warframe or Operator at any time. This is especially useful during early stages of the Teralyst encounter, as Vomvalysts are often scarce.
  • Eidolon Vomvalysts count towards Riven Mods challenges requiring Sentient kills, and are the easiest Sentient unit to kill.
    • Do not underestimate them, though; the basic projectile attack of Vomvalysts is still reasonably powerful. When hunting Eidolon Teralysts, they should not be ignored - both due to the fact they support/protect the Teralyst, and due to their damage output.
  • Ivara can steal loot from the Vomvalysts using Prowl130xDark.png Prowl.
    • Vomvalysts cannot be stolen from while they are in spectral form.
  • Vauban's Minelayer130xDark.png Minelayer in Tether Coil mode has a curious interaction with Eidolon Vomvalysts, where it will rapidly attempt and fail to tether them, dealing damage each time, rapidly killing their physical forms with little difficulty.


  • Eidolons in Greek literature are spirit-like images of a living or dead person.
  • Still in Greek, vómva (βόμβα), means bomb, probably a reference to their explosive projectiles, how they explode when killed or when they enter their ghost form.
