When you touch this tarnished doorknob to a wall, a door to the other side of the wall instantly forms.
Consumable 500 gp
Utility Power Consumable (Minor Action)
Effect: You place the doorknob on a wall adjacent to you and create a 5-foot-diameter passageway. The opening can be up to 2 squares long, and it leads to the area directly on the other side of the wall. Until the end of the encounter, creatures can use the passageway to move through the wall. The doorknob does not work on a horizontal surface. If a creature is in the passageway when it vanishes, the creature is shunted to the nearest unoccupied space. The passageway does not compromise the wall’s structural integrity.
