TheBigBB - so you send out, what - 2 Arcane Blasts, then lob an an Arcane Bolt (wait, what is this? new spell? Just tried finding it on the web and keep finding a boss spell that does 13k damage, I'm certain WE don't get that... ;P )

So...
Arcane Blast,Arcane Blast,Arcane Barrage,Arcane Bolt, repeat?
