It's more a case of the more things you try to do with a spell the weaker it is (I think) so something like a fireball is fairly strong cause all your doing is throwing a large bit of fire while raising flaming zombies is a bit less potent but slightly more applicable to situations. It's a thing of utility vs power I think. Letter Bee will have to clarify as it's his system
