Gun
Allows a player to shoot another during the day, killing them instantly.
Usually have a 50% chance of revealing the shooter, a few roles disobey this rule.
Fabricated guns kill the shooter, and have a different message if the gun reveals.
If the gun does not reveal, it appears the same as normal shot not revealing.

Knife
Allows a player to stab another during the day, causing them to bleed.
Bleeding targets die the next day under normal conditions
Can be healed, but Monk does not save.
Vest delays death by one phase (next night).
Always reveal, except for Slasher knives, which never reveal.
BUG(?): if a Slasher exists in the game, no knives will reveal, not just the ones the Slasher uses
Fabricated knives cause the target to trip, and fail completely, not killing the target.

Vest
Saves the player from one kill attempt.
Delays bleeding and poison by one phase.
Can stack.
Fabricated vests do not save.

Snowball
Allows a player to throw a snowball at another player, roleblocking them the next night.
Fabricated snowballs do not roleblock.

Key
Allows a player to lock themselves in for the night (day action).
A locked in player cannot perform their night action, and cannot be visited by anyone.
If a Watcher visits a locked in player, they will see them visit themselves.
note: A Cthulhu can make itself go mad by locking itself in.
Fabricated keys will rust away at the beginning of night and not work.
The day action exists for both fabbed and real keys.

Crystal Ball
Allows a player to choose a target each night to reveal upon death.
If the player dies, the target’s role will be revealed to all.
Functionally the same as Oracle.
Fabricated crystal balls do not function.
The player gets no night action for the crystal at all, making it easy to spot a fake.

Bread
If a Baker is in the game, all players start with 3 Bread.
If a Baker is in the game, and no Baker is alive, famine begins and each player’s bread will deplete a a rate of one per phase (day or night). (Note: the Learn page says day. This is wrong)
If a player has no Bread left at the start of a phase, the player dies.
Can stack.
Fabricated bread is not counted in the player’s Bread count (probably, no one ever fabs bread so unconfirmed)
note: i have not updated this since turkey was added

Doll
If the player holding the doll dies and the Creepy Girl is alive, the Creepy Girl wins the game.
The player with the doll must pass the doll at night.
