I think what he is asking is which spells the your battlefield AI won't use after your scripted commands have run out. And yes, I've never seen a blood mage cast reinvig on his own in the unscripted part of the battle.

As far as other spells that are not used... well, there are a bunch. But I can't begin to list them here. It just takes experience... knowing what the AI will start to cast when your script runs out.

I can say that if you give an elemental summoning mage extra gems, they will just summon like mad. They'll even override your script to summon something like a fire elemental. So pass out your gems wisely.
