All-or-Nothing Coin

Wondrous Item, Rare

''A large, brass coin. There is a simplistic face embossed on either side of the coin. On one side, the face smiles joyfully. On the other, it weeps madly.''

''Once per day, replace any d20 roll with a single coin flip. Heads is a Critical Success, Tails is a Critical Failure.''

Yet to be used.

Probably for the best.
