Coin of Gambling

A coin made out of mysterious  metal. One side resembles a head of a jester. Other side resembles a stinger of a scorpion.

Instead of rolling a D20 test, you can use the Coin of Gambling to decide the outcome of the roll. Flip 1d2; on Heads the roll is considered as 20; on Tails the roll is considered as 1. Both results will have a critical effect determined by the DM.

You can use this feature once per 7 days.
