Barb Split (Euphoria)

Pseudopod. Melee Weapon Attack: +12 to hit, reach 20 ft., one target. Hit:  (3d6+3) bludgeoning damage plus (2d8) acid damage.

Euphoria Breath (Recharge 5–6). Barb Split exhales a puff of euphoria gas at one creature within 20 feet of it. The target must succeed on a DC 17 Wisdom saving throw, or for 1 minute, the target can’t take reactions and must roll a d6 at the start of each of its turns to determine its behavior during the turn:

1–4. The target takes no action or bonus action and uses all of its movement to move in a random direction.

5–6. The target doesn’t move, and the only thing it can do on its turn is make a DC 17 Wisdom saving throw, ending the effect on itself on a success.
