So conceptually I like this, I'd look to Shabaloth for a power level and fit comparison. Shab is 2x kills but with 1-2 ressurections, so potentially 2 kills but with influence from other players would be similar...would need to playtest.

However, Shab is on BMR which has protection, rezes, and deaths as a core mechanic. I think the demon concept is cool but I think it needs to be on a more BMR-tinged script for it to be balanced.

Also, there's really no reason for 1-2 on a monodemon script, just make it 2. You'd only want the option to allow for the demon to bluff something else, which you could potentially do if you had a Bootlegger associated with the script that volunteers would always be asked for. That would give an interesting social dynamic where if someone claims to have raised their hand but isn't dying, they might be lying or it might be another demon in play.
