I meant to add that this skill could work for druids as well.If mages have energy problems, think about the poor druids who didn't get any energy cost reductions..
Example, A lv 35 ice shards cost abt 260 energy cost whereas a lv 35 storm cost 450 energy.. Ouch...
And deathreaver, I am sorry for my rudeness. My point was, it gets real hard to maintain energy, even at my puny level
