You regain all expended uses when you finish a long rest.

Born of the Furnace
At 17th level, you have developed an immunity to all fire damage, including infernal fire and lava. When you cast a spell that deals fire or radiant damage, add your Wisdom modifier to that damage. You also gain resistance to bludgeoning, piercing, and slashing damage from weapon attacks.
