4th ring Wyrd, Abjuration
Ritual - does not require spell slot, takes 10 minutes longerYou hide a chest and all its contents on the Ethereal Plane. You must touch the chest and the miniature replica that serves as a material component for the spell. The chest can contain up to 12 cubic feet of nonliving material (3 feet by 2 feet by 2 feet).
While the chest remains on the Ethereal Plane, you can use an action and touch the replica to recall the chest. It appears in an unoccupied space on the ground within 5 feet of you. You can send the chest back to the Ethereal Plane by using an action and touching both the chest and the replica.
After 60 days, there is a cumulative 5 percent chance per day that the spell’s effect ends. This effect ends if you cast this spell again, if the smaller replica chest is destroyed, or if you choose to end the spell as an action. If the spell ends and the larger chest is on the Ethereal Plane, it is irretrievably lost.
If you attempt to cast this spell while a chest from a previous casting is still active, the spell fails.
