Demon concept
I have an idea for a homebrew demon, but I'm not quite sure how I would write up its power. I wanted to get some help working it out.
The idea is a demon which allows the evil team to pass notes to each other at night. Something like:
Each night (except the first), choose a player, they die. All players know that [this demon] is in play. All players pass the storyteller a note at night to be delivered to another player. Notes from good players may not be delivered.
The idea being that I don't want the act of passing a note to give away clues about the evil team (paper wrustling, pencils scratching), so it seems like I have to open it up to everyone to write notes to each other. Then we have to make notes between good players unreliable so that it's easier for evil to bluff as good characters. "Did you get my message? No? Guess the storyteller discarded it."
I think the main idea behind this is it guarantees evil can discretely communicate and coordinate, even if they can't meet privately during the day, at the cost of announcing the demon type to the good team.
