Oh, you know. Throw a novice necromancer at a living subject and you can get all kinds of things going wrong... just the mundane stuff, though. They overdo it on cell growth and swell something up, kick off a cascade and necrotize tissue they didn't mean to kill, fiddle with one bit of the body and never realize how it'll wreck something else down the line... humans are fragile, you know?
