I want to say it can kill you as rot kills you if it runs you out of con. I haven't played a necromancer that's had it and I could be wrong.

Jullias' shrine, once upon a time.

No idea.

A part of the area that was never finished, to the best of my knowledge. I occasionally poke Jullias about this when I see him.

There's an edge that makes these things matter; otherwise they generally don't.
