Wondrous Item, Rare, 17,600 gp
(Requires Attunement)
This cube is about 1 inch across. Each face has a distinct marking that can be pressed. The cube starts with 36 charges.
You can use an action to press one of the cube’s faces, expending a number of charges based on the chosen face, as shown in the Cube of Force Faces table. Each face has a different effect. If the cube has insufficient charges remaining, nothing happens.
Otherwise, a barrier of invisible force springs into existence, forming a cube 15 feet on a side. The barrier is centered on you, moves with you, and lasts for 1 minute, until you use an action to press the cube’s sixth face, or the cube runs out of charges.
You can change the barrier’s effect by pressing a different cube face and expending the requisite number of charges, resetting the duration. When you press a different face, the current face effect ends.
If your movement causes the barrier to come into contact with a solid object that can’t pass through the cube, you can’t move any closer to that object as long as the barrier remains.
