Magic blasts, yes. Magic missiles are useless.
I don't agree. I have Magic Missile lvl. 13 now, combined with Mana Effeciency 5 and Destruction 5. There's a 1 sec cooldown and you do hundreds of damage, and you can hit 4 targets at once. That really is overkill just as much. When fighting a large mob, having only Magic Blast and Firewall might not be enough (ofcourse, by that time, you can use a bow for the remaining enemies). I don't have Magic Blast, but Magic Missele. Works fine, no one can beat me.
