Demon Transformation

The user appears to turn into a monster. In actuality they are encased in a powerful illusion. Any strike that the ‘illusion’ makes will feel real, however the user must work with their illusion to make the physical effects come out. A strike of a claw would be that of a blade, being smashed by a hand would be that of a powerful attack. The damage feels like what the person thinks the monster is capable of doing even if the damage is really not all that bad.
