Interesting. About a month ago I made something which is pretty much an elite version of the Vile Host.
The Shadar-Kai Deathmaster splits into a zombie and a wraith when bloodied.
I'm curious if that's just a case of parallel creation or if Ari saw my post and was inspired.![]()
Oddly enough, that's something I considered myself, like a "Horseman" that, when bloodied, is unhorsed and becomes "Soldier" and "Warhorse". This is in no small part inspired by Warcraft 3's Elf Archer + Hippogriff = Hippogriff Rider.Parallel creation, I'm afraid. It was actually inspired (very roughly) by something a friend of mine did in our 4E playtest campaign.
My one complaint is that I would have preferred the "Codex of Betrayal" article on Alloces before this bestiary, but its a minor complaint.
Those are some very cool, and very disgusting, monsters in there. My two favorites are shrieking steed (though it seems to be missing its spider climb movement trait) and the carpets of flesh. Nasty.
