All-In Coin

A simple copper coin with a helmeted head on one side and a salt shaker on the other.

All In Flip. For a free action, you flip the coin before rolling for any attack or ability roll. A 15 to 20 on the subsequent roll will result in a critical success while a 1 to 5 on the next roll will result in a critical failure. This ability can only be used once per long rest.
