necrotic termination

9-level Necromancy

You cause the cyst of a subject already harboring a necrotic cyst to physically and spiritually enlarge itself at the expense of the subject's body and soul.   If the subject succeeds on a Constitution saving throw, she takes 17d6 points of damage, and half the damage is considered vile damage (see necrotic bloat).   The subject's cyst-derived saving throw penalty against effects from the school of necromancy applies.   If the subject fails her saving throw, the cyst expands beyond control, killing the subject and digesting her soul. Raise dead, resurrection, true resurrection, wish, and miracle cannot return life to the subject once her soul is digested—she is gone forever.   On the round following the subject's death, the cyst exits the flesh of the slain subject as a free-willed undead called a Skulking Cyst.
