This, in my opinion, is the absoulte best monstrous pages. Both for quality and quantity it hasn't been outdone. I don't know if "walking corpses" is just a template ripe for inspiration or if Schwalb has a thing for undead the way he does for demons, but I'll take it either way. If you're intimidated by all the different monster expansions and you only want to get one, make it this one.
