Jsk Feats:Arcane Adept

You have learned to regain some of your magical energy by focusing on the subtle weave of magic that permeates the cosmos. Once per day when you finish a short rest, you can choose expended spell slots to recover. The spell slots can have a combined level that is equal to or less than one-third of your character level (rounded up), and none of the slots can be 5th level or higher.
