In the recent Unearthed Arcana about Psionic powers, one of the abilities is
Ego Whip (3 psi) - As an action, choose one creature you can see within 60 feet. The target must make an INT saving throw. On a failed save, it takes 3d8 psychic damage and is filled with self-doubt, and on its next turn, it can only take the Dodge, Disengage, or Hide action. On a successful save, half damage.
Against a Black Pudding who has immunities to Charm or Intimidation, would that attack hit or not?
Further info on this UA group of abilities is the ability
Forceful Query (2 psi) - As an action, you can ask a question of one creature that can see and hear you within 30 feet. Must be a yes/no question. If creature fails WIS saving throw, they must tell the truth. (Immune if charm-proof)
It's this last part in parenthesis that I want to emphasize: The designers took the time to mention that THIS ability will fail if your monster is charm-proof, yet didn't do this for the Ego Whip. With that as a counter-point, should Ego Whip be fixed to be considered a charm that a charm-proof monster is immune from?
