You can add a bonus of 15 to any ability check, attack roll, or saving throw you make. You can do so after the result. Once you use this boon, you can't use it again until you finish a short or long rest. When you roll a 1 on the d20 for an attack roll, ability check, or saving throw, you can choose to reroll the die and must use the new roll, once per turn. You gain a +2 to your charisma score and maximum, to a limit of 22.
