Actually, I'm glad to hear you disagree with me.

Does Conjuration 3 do you any good, though, if you haven't opened up any other paths, and are facing troops to large to trample?

Of course, if you're facing water blessed giants, destruction doesn't hurt as much since you're capped at 10 attack with your standard troops. Then a ranged attack starts looking a bit better. Standard giants, though, destruction looks like it could be quite useful, armor of achilles... Since Jotun focuses more on quality than numbers, individual target spells are more effective than they would be against, say, Ctis.
