Leoric sent my zombie dogs down with one swipe to start the battle, and I had just summoned them so they were on cooldown. That was a bit nasty but I didn't really take much damage otherwise. I was a bit dismayed that my summons went down so easily to a mini-boss, like in Diablo 2 the act bosses disintegrated Necro summons almost immediately, and if the equivalent of Blood Raven can send them packing so easily... yikes.

Walter: No, Donny. These men are cowards.
