Syu Tak-nwa (Level 16)

Tak-nwa's familiar is an elephant hawk moth named Yon-so. Yon-so has a fly Speed of 40 feet, darkvision, and scent as an imprecise sense to a range of 30 feet.

As long as Tak-nwa has a creature Grabbed with her hair, the creature cannot breathe and must succeed at a DC 5 flat check check any time they attempt an action that involves speaking (including linguistic effects and Casting a Spell with a verbal component). On a failure, the action is disrupted.

Tak-nwa has mastered using her prehensile hair in combat. She can use her living hair to perform precise tasks such as picking up objects and performing simple Interact actions, and she can automatically Grab with her hair, as the creature ability. She can also deliver hexes through her hair. Whenever Tak-nwa successfully casts a hex focus spell that requires 2 or more actions to cast and that doesn't require a spell attack roll, if her target is within reach, as part of the spellcasting activity she can make a hair Strike against the foe before applying any effects of the hex. If this Strike misses, the hex has no effect.

The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
