Semi closed with a twist: Players who are nightkilled do not die.
Instead, NK targets are secretly turned into Tree Stumps (allowed to post, votes will appear in votecounts, but not actually in the game and their votes do not really count). When lynch-or-lose ratio is hit, all Stumped players die and flip together.
Possible Roles:
Doctor - Protect a player from being Stumped at night. Saving a player informs the stumper they failed.
Gunsmith - Give a player a gun. Guns are transferable 1-use Stumpeners.
Armorsmith - Give a player a vest, Vests are transferable 1-time Stump immunity - but you will be Stumped in their place.
Deceiver - Choose a Stumped player. That player will flip Mafia.
Phantom - If a stump when LYLO is reached, does not die.
Silencer - Target a player. If they are stumped, kill them.
Roleblocker - A player of your choosing cannot use their role at night.
Bomb - If a player stumps you, you also stump that player.
Tracker - Watches a target at night. If they use a role, the Tracker is notified.
Prodigy - May choose a role. Become a 1-shot of that role.
Not all potential roles will be in the game. All roles may be town or mafia. A player may have more than one role. There may be more than one of the same role. Roles may be 1-shot, 2-shot, or usable every night.
