Sings at people to make them feel less pain and heal faster. Doesn't regrow lost limbs or anything and also people still have to be treated or they'll heal Wrong (like if someone breaks their arm and she doesn't set the bone before healing them it'll heal at a 90 degree angle or something, or if there's something in the wound it needs to be removed, etc.)

CAN use this to attach extra parts to people though. like she could put someone's arm on someone else's chest and sing at them to make them "heal" together and then the person has an arm sticking out of their chest I will use this power responsibly nothing fucked up could come of this
