I'm currently casting my cold spells at level 34 while my Draconic Incarnations are being cast at level 29. I originally thought Savant didn't work with it but since Savant PrE gives me +6 caster levels and there is a 5 level difference I'm thinking that it might be that. If so if raising my caster level is not enough to boost damage is there anything else I can do to increase it?
