Hinge Rod

Short steel, knurled at the middle, with a pin at each end and heavier than it looks.

Only wizards and clerics may command it. Each charge fits the rod to a wall of wood, plaster, brick, or dry stone no more than two feet thick and swings a door-sized opening in it for ten minutes, closing on its own afterwards with anything in the gap pushed clear. It will not open worked stone, metal, earth that would fall, or any surface bearing a ward. The pins shear off when depleted.
