Bag of "Holding"

Xan Rockman here for the Bag of Holding. All I can say about this bag is that this is definitely called and marketed as a bag of holding. It certainly holds some things better than others!

This backpack can hold 1 cubic foot / 30 pounds of gear.

As an action, you can magically adhere this bag to a flat surface for up to 10 minutes. For the duration, the bag becomes rigid and can hold up to 500 pounds of weight against a force pulling parallel to the adhered surface. Any significant force pulling the bag perpendicularly away from the surface detaches the bag and ends the duration early.

Once used, this property cannot be used again until the next dawn.
