The necrotic entrailer is an undead which makes use of the unneeded bits from other undead like skeletons and zombies. The entrails of those undead corpses either desiccate quickly or slip out between open ribcages. The practical necromancer can use these supposedly unnecessary organs to fashion a necrotic entrailer. Creators of necrotic entrailers commonly use them as reconnaissance and/or assassination creatures because of their quick, silent nature and built-in escape methods.
