Magic Missiler is a Steam achievement in Retribution.
Getting it[]
Use any abilities (spells) until you have wasted 5,000 energy. You do not need to do it in a single match. You could just stay at wave 1 and spam abilities at empty space until you have it, although you will get it automatically by playing normally so there's not much point.
Note that energy drained by the Cataclysmic Hellblade does not count.
