This cube is about an inch across. Each face has a distinct marking on it that can be pressed. The cube starts with 36 charges, and it regains 1d20 expended charges daily at dawn. You can use an action to press one of the cube's faces, expending a number of charges based on the chosen face. Each face has a different effect: Face 1 (1 charge): Gases, wind, and fog can't pass through the barrier. Face 2 (2 charges): Nonliving matter can't pass through the barrier. Face 3 (3 charges): Living matter can't pass through the barrier. Face 4 (4 charges): Spell effects can't pass through the barrier. Face 5 (5 charges): Nothing can pass through the barrier. Face 6: Deactivates the barrier.
