Speaking of shamans, towards the end of THH Rupert and Fer-Rog are learning skin walking and Tom had already shown some proficiency in this, when he was able to make himself into an older looking version of himself. Rupert at least is able to switch between demon, orc and human. How extreme can these changes go? Tom already has a tail that can shoot lighting, could he grow a flamethrower on his arm or something if he wanted to? OR something less extreme like an extra set of arms like Reggie or Tizzy?
Ooh, if someone is powerful enough, can they force someone else to change appearance? If so, that would be a cool way to torture wizards, he could make them look at least partially demonic, and tell them that he took their soul. Although, wizards would probably be able to undo it eventually. I would say he could do it to priests, but that would be too cruel. It would be an awesome/evil joke to play on Jenn, or, if changing someone else isn’t possible, Rupert and Edwyrd could meet up with Jenn, and both show a bit of horn growing, or have vertical pupils, and let her think they have been “corrupted”. Tom would NEVER do this to her, but I can see Rupert changing his eyes to freak her out, if they were about to admit to her her that they were demons.
