| Golden Key | 5.30.2 | 
|
0 | Will not add to the player's key count, but when picked up, it will allow the player to use keys on anything that requires them without subtracting from their total for the duration of the current floor, even if the current number of keys is 0. There is a 1/50 chance for any given key pickup to be a golden key.  Sharp Key ignores the Golden Key and still subtracts keys from the key count upon use.
