Pearl of Power

Uncommon

Wondrous Item, uncommon (requires attunement by a spellcaster) While this pearl is on your person, you can use an action to speak its Command Word and regain one expended spell slot. If the expended slot is of 4th level or higher, the new slot is 3rd level. Once you have used the pearl, it can't be used again until the next dawn. The pearl's brilliant, nacreous quality fades to almost black after being used only to waken the following dawn.
