Eidolon Vomvalyst

Vomvalysts are Sentient creatures found in the Plains of Eidolon at night.

Tactics

 * Vomvalysts have two stages:
 * The first stage requires taking any damage like normal enemies.
 * After their health has been reduced to zero, they will turn into their spectral form and will only take damage from the Operator's Void energy attack. If their spectral form is not killed after a short duration, they will eventually regain their physical form.
 * Vomvalysts will perform a charge attack towards the Warframe or Operator if they are within its vicinity after its corporeal form has been destroyed.
 * Alternatively, a Vomvalyst's ethereal form can be killed by an Eidolon Lure.
 * Vomvalysts spawn in pairs, unless spawned by a Teralyst.

Tips

 * Vomvalysts currently 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 Prowl.
 * All party members as Ivara can steal from the Vom, potentially resulting in 5 core drops.
 * Vomvalysts cannot be stolen from while they are in spectral form.
 * Along with Intact Sentient Cores, Vomvalysts will also drop a replenishment orb, allowing the Operator to charge a nearby lure.
