Raven if u wanna have the ultimate mage class at higher levels u need to maximized skills: -Magic Missiles (possibly to lvl 15) -Fireball (the same like magic missiles) -optional Magic Blast (not so high dmg but good to instant kill)
and important skill for mage "Mana Efficiency" to lvl 5 so u will have reduced (50% or higher) usage of mana
Good Luck
Nope I still find fireball useless for mage I know It can dmg high and bring enemy to 10-20% of health but I had other skills that made me ultimate mage.Although many people say It is good. On my fifth playtrough as a battle mage I have found out that fireball IS pretty good spell but only after battle tower.I must admit that I have been wrong,but still my mage is strong enough to wipe entire army. I use many skills not just destructable skills like fireball. I am pretty happy with my ULTIMATE MAGE and I don"t have fireball Now its late I can"t edit my guide anymore but I doN"t care Those who read it will still find themself very powerful without fireball.
