Usvapna Quori

 Innate Spellcasting (Psionics). The quori’s spellcasting ability is Charisma (spell save DC 17, +9 to hit with spell attacks). It can innately cast the following spells, requiring no components:

At will: charm person

3/day each: detect thoughts, mind spike (at 4th level), dream, inflict wounds (at 5th level)

1/day each: Phantasmal Killer (at 6th level), compulsion

Multiattack. The quori makes four pincer attacks.

Pincer. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 10 (2d6 + 4) bludgeoning damage. The target is grappled (escape DC 15) if it is a Large or smaller creature. When a creature is struck by the Quori's pincer it must make a DC 17 Wisdom saving throw or become paralyzed until the end of their next turn. The Quori has four pincers, each of which can grapple one target.

Possession (Recharge 6). One humanoid that the quori can see within 5 feet of it must succeed on a DC 17 Charisma saving throw or be possessed by the quori; the quori then disappears, and the target is incapacitated and loses control of its body. The quori now controls the body but doesn’t deprive the target of awareness. The quori can’t be targeted by any attack, spell, or other effect, and it retains its alignment, Intelligence, Wisdom, Charisma, and immunity to being charmed and frightened. It otherwise uses the possessed target’s statistics, but doesn’t gain access to the target’s knowledge, class features, or proficiencies.

The possession lasts until the body drops to 0 hit points, the quori ends it as a bonus action, or the quori is forced out by an effect like the dispel evil and good spell. When the possession ends, the quori reappears in an unoccupied space within 5 feet of the body. The target is immune to this quori’s Possession for 24 hours after succeeding on the saving throw or after the possession ends.
