Once again, from the role list:
Whenever a player receives an item (or starts the game with one) they will receive the below info. Unless otherwise specified, all items can be stolen or sabotaged. Items are not revealed upon death. All items stack. When an item is used, the player no longer has it.
A player with a gun has a 1-shot kill that may be used at any time during Day Phase. Players will notify the mod of their use and the target in their role PM. The shot will be processed by the mod when possible, but will be retroactive based on the time the owner submitted the action. Additional time will be added to the Day Phase to account for the time difference. The player retains the gun until it is used. Guns may be sabotaged and stolen. Sabotaged guns kill their owners when used. Unless otherwise specified, the use of the gun will randomly (50%) reveal the identity of the shooter.
