Duvai's Zippy Delivery

You summon a tiny air elemental to a spot you can see within range. The air elemental is translucent, immune to all damage, and cannot interact with any other creatures or objects. It carries an open, empty chest whose interior dimensions is 1 cubic foot and can hold up to 30 pounds of material. While the spell lasts, you can deposit as many items inside the chest as will fit using an action to either add a single item weighing 10 pounds or more, or several items that’s total weight equal 6 pounds or less. You can then name a living creature you have met and seen at least once before, or target any creature for which you possess a body part, lock of hair, clipping from a nail, or similar portion of the creature’s body. This designation of a target does not require an action but must be done during your turn. The lid then closes

As soon as the lid of the chest is closed, the elemental and the chest disappear, then reappears in an unoccupied space adjacent to the target creature. If the target creature is on another plane, or if it is proofed against magical detection or location, the contents of the chest in an unoccupied space closest to you.

The target creature is made aware of the chest’s contents before it chooses whether or not to open it, and knows they have 1 minute to retrieve the items from the chest. No other creature can open the chest and retrieve its contents. Removing items requires an action for either a single item weighing 10 pounds or more, or for several items equal in a total weight of 6 pounds or less. When the spell expires or when all the contents of the chest have been removed, the elemental and the chest disappear. The elemental also disappears if the target creature orders it to return the items to you, which the elemental will do in 1 round. When the elemental disappears, any items not taken from the chest have a 5% chance of becoming lost in transport, becoming irretrievably lost. If the items are not lost, the items not taken from the chest appear in an unoccupied space closest to you.
