I like this type of thinking. Use what you have and the ressources you have access to, instead of being stopped doing stuff, just becauce of an "...if i only had *insert random term here*" :)
Great ideas and suggestions up there, too!
Maybe I should get rid of the Banish ability in my game. It's a non-elemental spell that doesn't even appear in the magic chart. It's only there because my Elementalist doesn't use light or dark magic. It only effects summoned creatures.
