A commercial climbing kit includes 50 feet of cable line, a grappling hook, harnesses, pulleys, pitons, a hammer, and crampons. Climbing kits allow you to attach yourself to the wall you're
Climbing, moving half as quickly as usual (minimum 5 feet) but letting you attempt a DC 5 flat check whenever you critically fail to prevent a fall. A single kit has only enough materials for one climber; each climber needs their own kit.
