From publisher blurb:
You came to this dank and musty hole in the ground in search of treasure and glory. What you found was death. The undead are a constant threat to the living, seeking to drain their blood, lord over them, add to their own ranks, or simply kill them because they are compelled to destroy what they can no longer possess. The five undead monster in this book include the 5E conversion of the deaded graveknight by the person who originally designed it for the Pathfinder system, the corpsipede--a giant undead centipede made from the parts of dead people, the skeletal wyvern, the soulless titan, and the undead scarab swarm. This batch of monsters will give your players nightmares for weeks!
These monsters are compatible with the 5th edition of the world's most popular roleplaying game.
