Artificial Dunamantic Crystal (Pocket Beacon)

This small, purple crystal is gently pulsing with a dim light of potentiality. 

While attuned to this crystal, you may use your reaction to add 1d6 to any attack roll, ability check, or saving throw that you make, twisting your own fate to a marginal degree

You may use this feature twice per day, with the crystal growing dark once both uses are expended, until the next dawn.
