You are able to take on a human-like form which disguises you to be more humanoid in nature. This doesn't fully disguise your true nature, but helps in social situations from causing people to be alarmed by you. This ability is magical in nature and costs 10 MP in order to activate it, and its effects last so long as you choose to maintain it or for 24 hours, whichever comes first. Maintaining this ability requires you to spend the MP every 24 hours.
If your MP would reach 0, you immediately lose the benefit of this alternate form and become your normal self.
This form provides little mechanical benefit however it allows some more monstrous player character choices (such as False Angels or Elder Things) from being immediately ostracized from societies. Most NPCs will recognize there is some "otherness" about the individual, but without further investigation it looks like little more than some magical alterations changing your body.
