All or Nothing Coin (DI)

All or Nothing coins are about 5 inches across and about an inch thick, minted from celestial iron with a twist of infernal iron. Each coin weighs one-third of a pound and is inscribed with the local kingdom's sigil. On a roll you would normally use a d20, flip this coin instead. Heads is a critical success Nat 20 (then add crit to your command). Tails is a critical fail Nat 1, DM choice on consequences if there are any.

This can be used twice per short rest & no features can change the Nat 1 if it is rolled using this coin (i.e. Halfling Luck, Lucky Feat, etc.). (DI Alias = !ancoin create to create the counter; !ancoin roll & reduce counter).
