Coin of Luck

Magical Item (Requires Attunement)
This magical coin has two charges. A user can choose to use a charge to instead use the coin to decide their fate. Once the coin loses charges, the coin is a mundane coin until it is recharged. The coin recharges on a short rest.
Instead of an attack roll, the user uses a coin for a critical success or critical failure. Advantage or Disadvantage is not given to the coin flip. For an additional charge, the user can choose to use two charges to “double down.”
Double Down. A user can flip the coin twice to test their ultimate fate. Double Fail or Double Success will give more dramatic results. If the results are mixed (i.e. Heads and Tails), the DM may use their discretion to decide the fate of the player.
