Intellect Devourer

Telepathy 100 feet (aura, magical) — A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn't give any special access to their thoughts, and communicates no more information than normal speech would.

Lifesense 60 feet — Lifesense allows a monster to sense the vital essence of living and undead creatures within the listed range. The sense can distinguish between the vitality energy animating living creatures and the void energy animating undead creatures, much as sight distinguishes colors.

Body Thief (manipulate, occult, possession) — The intellect devourer reduces in size and burrows into the brain of a creature dead for no longer than 1 day. At the start of the intellect devourer's next turn, the body revives at its maximum Hit Points, controlled by the devourer. The intellect devourer is conscious and can sense everything the possessed body could.

Any effect that ends the possession kills the host body with the same effects as Exit Body. The intellect devourer can't use any of the host creature's spells with Body Thief but can use its own spells.

The host body slowly decays while inhabited by the intellect devourer, becoming uninhabitable after 7 days unless preserved with Peaceful Rest or a similar effect.

Exit Body (move) —

Ravage (death) — The intellect devourer makes two talon Strikes against a Paralyzed, Restrained, or Unconscious creature, using the same attack modifier as its highest attack modifier.

These Strikes gain the death trait. If Ravage kills the target, the intellect devourer may use Body Thief against it as a free action.

Stolen Identity — While an intellect devourer uses Body Thief, it gains the ability to understand and speak all languages known by the host, as well as knowledge of the host body's abilities, identity, role in society, and personality. However, it does not gain the specific memories or knowledge of the host body.
