we begin to see some hints of his limits.
seems he gets all the powers but not as powerful as the original. for now it passes as him not having mastered the power.
he can't make more than one clone, he has a weaker psychic bond with his wolf, he can't choose his host, could have less control or energy output from the "green stuff"(TM)... also,
having the wolf out drains him, so it's probably the same when he uses the other powers, and he gets limited like that. a bit like some kind of mana reserves. though he doesn't seem tired when drained.
Amber's invisibility might be related to her emotions. maybe she gets visible the better she feels. so a big orgasm will make her stay visible for a few days
though she masturbates often, so it might have to be with a partner. some kind of feeling of being loved ? feeling
seen ?
