Firstly this game is fantastic, it makes my brain ache and I'm so glad to be exposed to this. It feels like a mind hazard. The way that it engages with,, violence and the things that you can do with other people makes me dizzy and deeply compelled.
Secondly, a clarification on a rules thing, the Orb-Weaver girl on a 10+ can "provide them with true death", is this a method of permadeathing player characters or just demons and NPCs?
