Dent's Dismissal

You dismiss a possession into an alternate plane within an object for safe keeping. When you cast this spell, you begin a ritual to transfer a medium or smaller mundane object, that is not bolted or attached, or a medium or smaller willing creature you can touch into a pocket dimension within a tiny object. This tiny object must be non-magical and you must be able to touch it for the entirety of the ritual. The tiny object becomes magical and can be detected as containing conjuration magic. When the object is targeted with a Dispel Magic spell, the tiny object is destroyed, and the contents are spilled out. 

As an action, you, or any creature you designate while casting this spell,  may destroy the tiny object and summon the contents inside.

A creature within the tiny object may remain inside the object with breathable air for a maximum of 24 hours. After 24 hours, the creature inside is automatically summoned and the tiny object is destroyed. 

When you cast this spell using a spell slot of 4th level or higher, the duration a creature may remain in the object with breathable air before being ejected is increased to 10 days. When using a spell slot of 6th level or higher, this duration limit is removed entirely.
