Roulette/Roll of the Dice (RotD)
– variant of
Percentage as a modular role. Needs one or more roles attached to it. Your ability is randomly determined to be one of the attached roles, depending on the chance. If the chances don't add up to 100%, then any unspecified space is assumed to be "Vanilla/No Ability". You know what ability fired.
Town Roulette (50% Cop, 50% Tracker)
would get a Cop result on their target 50% of the time, and a Tracker result on their target 50% of the time.
Town Roulette (25% Vigilante, 50% Jailkeeper)
would kill their target 25% of the time, Jailkeep them 50% of the time, and do nothing 25% of the time.
Mafia Roulette (1/3 1-shot Roleblocker, 1/3 1-shot Rolecop, 1/3 1-shot Traffic Analyst)
would have an equal chance of firing any of its three abilities, but only be able to fire each of them once.
Mafia Roulette (50% 1-Shot Bulletproof, 50% 1-Shot Ascetic)
would be immune to the first nightkill that targeted them half of the time, and immune to the first non-kill night action that targeted them the other half of the time.
Technically, a
Town Roulette (50% Doctor)
is equivalent to a Faith Healer, as is any single-role Roulette.
