Act 1-I really liked the goatmen with scythes. They also appeared in Act 2, but they were my favorites from Act 1, for sure.
Act 2-Claw Vipers were quite cool.
Act 3- Flayer Shamen-While they were increadibly annoying and did truckloads of damage with their firebreathing, they were awesome looking. Very unique how there is one flayer on top of another. Though I also liked the Water serpents and the Undead Flayer dolls.
Act 4- Definetly the Corpse eaters. Their attack is just classic, and I couldnt stop laughing even though I was dying real quick.
Act 5-The Death Lords with the double swing attack or the yetis. The Death Lords, were, by far, the most damaging creature you found in bunches in DII.
So what does everyone else think?
