Bag of Portals

This bag is made from an alien iridescent leather. It can hold up to 20 pounds in a 1 foot cube.

As an action, you can create a small one-way portal that links the opening of the bag to an unoccupied space within 90 feet for 1 minute. While holding the bag, you can make attacks or cast spells as though you were occupying the portal exit’s space. While the portal is active, you can use your action to squeeze yourself through the portal and emerge on the other side, but doing so destroys the portal. If you make another portal, the older one disappears.

If you use your action to focus on the bag each round for an uninterrupted minute, you can cast the Teleport spell. Once you’ve used this feature, you can’t use it again for 7 days.
