(I actually have been slowly working on leveling a lock, but this is a question from my little brother...) somehow, when he was questing, he managed to remove Firebolt from his imp's control bar. It was set to auto, so the imp still uses it, but it's a little weird and we've been trying to find the ability to put it back in the bar. (Also, to prevent this from happening again, set the action bars to locked.)
Anyway, our question is--where are the pet abilities located so we can get Firebolt back? It's not in the spellbook, and we can't think of where else to look.
