Grappling Hook

Source: D&D 5.2 SRD Equipment

Cost: 2 GP

As a Utilize action, you can throw the Grappling Hook at a railing, a ledge, or another catch within 50 feet of yourself, and the hook catches on if you succeed on a DC 13 Dexterity (Acrobatics) check. If you tied a Rope to the hook, you can then climb it.
