One main comment,-Hellspikes! Good damage and cannot be resisted.
Lightning is a little too random and mana-expensive for effective use, burning wall is far superior.
Meteor strike is fine, but don't expect to finish the game with it.
For bosses, Curse(survivors), freeze, life leach, or elemental hail. Then resurrect them if you need a friend. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
Also, when divine, one point in divine death is damn cool for wasting imps. <img src="/ubbthreads/images/graemlins/up.gif" alt="" />
Good stat point distribution. I usually have a little more agility and less mana.
