Pearl of Power:
While looking like an ordinary pearl, a Pearl of Power can be used by a spellcaster to regain their strength. By using an Action to say the command word, the user can regain an expended spell slot of 3rd level or lower. Attempting to regain a higher level spell slot results in a 3rd level slot instead. Once used, a Pearl of Power cannot be used again until the following dawn.
This item requires attunement by a spellcaster.
