Adrie's Ethereal Well

You create a small portal into the ethereal plane, where you can store small objects. The portal appears as a 5ftx5ft cube, that appears in a unoccupied 5ft space within 30ft of you of your choice. You can place an object that is less than 5ftx5ft into the well as a bonus action when you are standing within 5ft of it. The well can hold as many objects as you like, as long as they objects fit within the 5ftx5ft cube. The well does not impede movement, and can be traveled through freely. You can dispell the well as a bonus action.
