All or Nothing Coin

This Coin is said to have been originally been crafted by an Archpriest of Tymora, the Goddess of Luck, however it has over the centuries found its way throughout the lands.

The Coins "Head-Side" is made of Gold, with a laughing face as its motif, and shining rainbow coloured opals as its eyes

The Coins "Tails-Side" is made of rusting Iron, with a frowning face crying small tears as its motif, and pearls as the eyes and tears.

3 Times per Day when you make a Dice-Roll that would require a D20 (Attack Roll, Skill Check, Saving Throw) you can instead decide to toss a Coin, treating a Heads as a Nat 20 (Critical Success), and a Tails as a Nat 1 (Critical Failure). The Critical Failure can not be mitigated or negated in any way (f.e. reliable Talents does not allow you to treat the 1 as a 10).

This Coin gives Advantage on any Check related to Gaming Sets, a desire to engage in all kinds of Gambling, as well as an urge to constantly flip it when the Creature attuned to it isn't doing anything else.

The Creature currently attuned to this coin can't have it stolen from them, the only way it can pass from one Creature to another is for the Creature currently attuned to the Coin to loose a game of Luck of their choosing, after which the Winner instantly attunes to the Coin ignoring the usual requirements for attuning to an Item. Each time the Creature currently attuned to the All or Nothing Coin looses in a game of Luck it has to succeed on a DC 13 Intelligence Saving Throw to not bet the Coin, potentially loosing it. The DC of the Saving Throw increases by 1 for each consecutive Game lost, and resets back to 13 on a Win, and each Day at Dawn. If the Creature attuned to the Coin dies before it can pass it on the Coin vanishes and teleports into the Pockets of a wandering Priest of Tymora who will give the Coin to someone who might need a little Luck.

Notes: creature who bested the previous owner in a game of Luck (f.e. playing with a Gaming Set)
