Mike, add the weakness of sunlight if you want to do light, or weakness of a vampire/ Lycan fang or caninie, you cannot have the character who would be a weakness to your character. dia is sick, but I guess I I'll let her know anyway . Or weakness of time, maybe there a short time that he can use his power like that. It's hard to find a weakness that cannot be over powered anyway, but you just need to not OP him or hire him to get family. Maybe you shouldn't be able to rengenerate at all during the time of wounding
