Occasionaly the grapple may break, so it is a good idea to have multiple grapples your inventory. When a grapple breaks, the following message appears in the player's chat interface: "After untying the rope, you find that your grapple is broken and useless".
Some grapple spots do not require players to bring their own grapple, as one may be stored in a hidey-hole. Alternatively, it is recommended that players craft an enhanced grappling hook which can be added to the tool belt, reducing the need to bring a grapple to each location.
Players can use an off-hand variant of a crossbow to grapple onto objects.
