Aura faint transmutation; CL 5th
These gloves are made of a fine metal mesh. If a creature wearing rubble gloves touches a 5-foot square of stone or earth floor, rubble roils to the surface, making the square difficult terrain. Using the gloves is a standard action that does not provoke attacks of opportunity. The wearer can use the gloves to create up to 20 squares of difficult terrain per day.
