Flame Spear and Ice Hammer having mediocre power for their casting time?! You do realize that both spells have an innate 25% chance to do double damage, right?
Those are my favorite spells now. The other night I was fighting in the blight and attacked a, think it was one of those Abominations. Perfect Spell - Fusion Burn - Multi-Cast II - Fire Spear IV and I did approximately 3000 points of damage! Tech 'em with stuff like Critical Damage and you have a spell that can just belt out the damage.
Ice Hammer does Crush Damage, and it seems to hurt everything well, especially creatures with shells like beetles and fyakki.
I definitely agree about the Fire and Ice Elements giving too little, though. I was in a group of 6 or so people, and I was only buffing 2 dragons, yet I still ran out of Infix Fury only half-way thru the recycle on the fire element!
