Orb Lightning works fairly well also, especially when massed. I've found Orb Lightning to be preferable to Thunder Strike in many situations.

Oh, right, I forgot to mention Magma Eruption, which is also very effective at clobbering AI hordes. But requiring both F and E makes it a bit harder to get a hold of.

Isn't Orb Lightning short-range? And it doesn't seem to hit too many troops. How many mages do you need to clear a significant fraction of a 300-troop AI army?
