You have inexplicable luck that seems to kick in at just the right moment, and wild possibilities swirl and dance around your mind.

You have 3 luck points. Whenever you or an ally within 5 ft make an attack roll, an ability check, or a saving throw, you can use your reaction to spend one luck point to roll an additional d20. You can choose to spend one of your luck points 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 can also spend one luck point when an attack roll is made against you or an ally within 5 feet.  Roll a d20 and then choose whether the attack uses the attacker's roll or yours.

If more than one creature spends a luck point to influence the outcome of a roll, the points cancel each other out; no additional dice are rolled.

alternatively, you may activate lucky before a dice roll, and reverse the outcome of the roll. the inverted roll is equal to 21 - the original value. (e.g 1 <-> 20, 10 <->11, 19 <->2). you can not use a luck dice on the new role after this.

You regain your expended luck points when you finish a long rest.
