This ring has 1 charge that reset at dawn. The charge can be used to summon a door to the Magnificent Mansion
spell. You do not need any components for the spell or the rings use.

In addition there is this change, "You can store items and people in your mansion. The spell is tied to the ring so if the door closes everything and everyone in the mansion will be trapped there until someone uses the ring again. The door stays up until you dismiss it or summon it to a new location or you die."
