A climber's kit includes special pitons, boot tips, gloves, and a harness. You can use the climber's kit as an action to anchor yourself; when you do, you can't fall more than 25 feet from the point where you anchored yourself, and you can't climb more than 25 feet away from that point without undoing the anchor.

The pitons, boot tips, gloves and harness contained in this kit are everything an adventurer needs to climb a sheer rock wall or the side of a mountain. It only requires sufficient rope, will and bravery, and someone with the strength and guts to challenge gravity itself. The kit is cunningly designed so that it can be easily attached to a backpack or worn as a wide belt for easy access, depending on what the user needs.
