I personally would like this spell removed completely. There's no fun having a spell that removes all buffs, basically negating any tactic or any build with luck for me. Making it remove buffs for a certain duration would be even worse in my opinion, everyone will have lv 5 and it will keep your buffs off for endless amounts. The less luck, and chance in the game, the better it will be in the end. If they keep this spell I'd make it cost 500 mana
just to make it super rare.
