Small changes from original request have been made, with knowledge and discussion of the person who made the formal request. Specifically:

* Damage and how it's done,

Because of the inability to make a prompt which will auto-cancel out after a specific time.

......

People who are being converted by the cult now take 10 damage in the first
place. Additionally, those who resist take a little bit more damage and get
a fair number of messages showing their great painful resisting and whatnot.

Light and fun.
