I'd be interested to hear what spells people use?
Is it just me or do people use blink, arcane and spell blast. I seem to either blink
around the battlefield casting spellblast. Or I get an earth elemental to do the aoe
spell. And that seems to be it tactically, not much variation 
oh and touch of entropy for high hit point units.
I'm playing on hard level at the moment.
thanks
