Demon Transform

You cast aside your human blood to tap into the power of the demons. Once every day, you can transform a body part into that of a demon's for full control, or transform completely as a demon, but lose control.

Demon Appendage You transform one piece of your body into that of a demon's. You have full control of yourself, but take a half hit-point of damage per turn sustained. You will transform back when the encounter ends.

Demon Pledge You fully transform into a demon, taking the form of an infernal beast. Once per turn, take a INT saving roll. If you succeed, you attack an enemy. If you don't, you attack an ally. Your turns cannot be skipped and you will transform back when the encounter ends.
