My favored soul is lvl 8, and I play mostly like a buffed melee. However, I like casting some offensive spells when I have the opportunity, such as Searing Light and Holy Smite. Of course later I'll be using Bladed Barrier a lot, and maybe Flame Strike.
I know there are easy to find clubs with Potency VI and such enhancements, but I use a greatsword all the time and would like not to change to a club every time I'm casting a spell to get that +50% damage. So, are there other ways to improve spells such as Blade Barrier, Flame Strike and Holy Smite? I basically want to increase my spell damage without having to drop my greatsword..
