Hum...why do the spells allways deal the same damage? it contradicts the battle mecanic.

Opps sorry I mean to add inflict 25 fire damage and etc. I'll change them now =p. They deal the same damage because it would be illogical if fire is stronger than ice then ice is stronger than wind and etc. So pretty much the have the same set of damage kinda (dude read them carefully) to even things out.
Oh on the side note I change the battle mechanic.
