A coin with one face displaying a black background with a white lobster head on it, and the other displaying a gold background with a blue wave in the centre.

A character may choose to flip the coin. For the character who flips it, they will flip a coin and see the outcome. If it lands on the black/white face, the next Nat 1 will become a Nat 20. If it lands on gold/blue, the next Nat 20 they roll becomes a Nat 1.

This only takes effect for their first Nat 1/Nat 20 since the items use. One use per long rest.
