Boon of Mastered Abilities

6th level boon 

Choose one consumable ability your character has that has a limited number of uses, such as a fighter's second wind or a cleric's channel divinity. The amount of time you can use this ability before it needs to be recharged increases by one. This boon may not be used to increase spell slots.

You may take this boon more than once, but never more than once for the same consumable ability.
