Eidolon Lure

Eidolon Lures are Grineer utility devices based on the Regulator, found in the Plains of Eidolon, only appearing at night near the Grineer encampments and automatically despawning when daytime starts by flying up into the sky. They are used as a defense to trap and distract Eidolon Vomvalysts wandering near the camps, as the Grineer's conventional firepower proves otherwise useless against Sentients. They also function as tethers in the final stage of an Eidolon Teralyst battle.

Players cannot directly destroy these devices, instead they can only be damaged until they enter a disabled state and then hacked (similarly to Bursas). Once hacked, they will start following the player who hacked it and accumulate charges from absorbing the ghostly forms of Vomvalysts. Players can heal and protect the lures with Warframe abilities.

Lures will keep the Eidolon Teralyst in place and will prevent it from teleporting to another location.

To charge them they must absorb the energy of 3 Vomvalyst cores. The Vomvalysts should be damaged with player weapons until they glow blue and the lures are moved close to them.

Current charge level of the lure can be seen by how many blue exhausts are coming out of the bottom. Two means it is charged.

When you bring a fully charged lure (lures that have absorbed 3 Vomvalysts each) to an Eidolon Teralyst fight, then when the Teralyst dies it will drop brilliant shards. They bind it and force it to drop better loot, the more lures you bring the better, up to 4.

Lures currently only reliably work when the host is the one to hack them. This can be noticed by the host's lures extending beams of light, and other players' lures do not.

Lures will stop following a player if they force revive or bleed out. The lure will still show the X to Hold prompt, it is required to press X on them *twice* to make them follow the player.

Trivia

 * Occasionally the Lure will give off a garbled imitation of the typical Sentient wailing sound, presumably in a similar function to a duck call.
