Boots of Luck (5e Equipment)

Wondrous item, rare (requires attunement)

These boots immediately attune to you upon being worn.
While wearing these boots, whenever you make an attack roll, ability check, or saving throw, you can roll another d20 and choose either. You can choose to use this feature after you roll the die, but before the outcome is determined. You choose which of the d20s is used for the attack roll, ability check, or saving throw.
You regain use of this feature after finishing a long rest.
