Xilvirek

A xilvirek can sense the presence of creatures with an Intelligence of at least -3. Creatures that have silenced their thoughts through magic or other means can potentially counteract this sense at the GM's discretion.

30 feet. A creature that begins its turn in the area must succeed at a DC 32 will save or become Fascinated with the xilvirek. If the creature is already fascinated by the xilvirek and fails its save, the creature is compelled to approach the xilvirek and allow itself to be Grabbed, which ends the fascination.

The xilvirek retches a small pool of debilitating, acrid bile onto itself. All creatures within 30 feet take 4d6 acid damage as they inhale the bile's noxious fumes (DC 32 fortitude save; on a failure, the creature is Sickened 1, or Sickened 2 on a critical failure). The xilvirek can't Disgorge Bile again for .

The xilvirek has two tentacles on its back that it can use to suck the life from its prey. A creature that starts its turn Grabbed by the xilvirek becomes Drained 1, and the xilvirek regains 20[healing] HP. The drained value increases by 1 on each subsequent round that the creature starts its turn grabbed, but the xilvirek doesn't regain additional HP from draining the same creature more than once per day.
