this will create a prisim of ice /varying in size depending on blast size it would be an excellent challenge if there was a boss that could only be hurt by it's own attack (energy beam) then you make a few pillars of ice and relfect it. Also if cast on yourself (will require certain amout of potions) it will tempraly grant you an ice defense ability that will do one of three things slow thier attack and movement. deal some ice based damage. or it can temoraly freeze them in a block of ice and they die instantly when you break it open (will not work on bosses or sub bosses)
