A blackened Imperial coin distributed by the Antari Empire, it has the basic marking of a silver piece however it seems to have been charred black.

When used this coin will allow you to re-roll once roll from any source whether this is you, another player, or even the Dungeon Master. 

This effect can only be used and its charges reset every dawn.

Notes: You spend a hour with the coin, when you first attune to it you feel it has a deep pull, almost as if it is warping the very time around it.
