One-Shot

One-shot roles can only utilize their special abilities once during the course of the game. The most common use of this role is to limit the power of Vigilantes, but there can also be one-shot Cops, one-shot Bulletproof Vests, and one-shot Governors, etc. Most roles can be adapted to be "one-shot" in nature.

In most cases, when a roleblocker targets a person using a one-shot power, the power is considered used and gone. Exceptions are made based on an individual game's theme and flavor or individual mod preference. The exact effects of roleblocking a one-shot power should be decided during the design of the game.
