Ok,Nekomancer? Can I give you some advice?

You seem to be making a character that is very powerful in a relatively narrow field that will diminish in utility when this game continues much into upper (or really even mid-) levels of the game.

Put more simply, this character will dominate any situation where roasting a handful of goblins is called for, but will have a comparatively difficult time once things like golems (or any number of other threats that can't be effectively dealt with by blasting) become more commonplace. Don't forget, Fire Resistance is one of the most Common Damage Reductions among monsters, so that lack of flexibility will hurt as early as Level 3-4
