Mithril grapple tips are used to make a mithril grapples which are used with Agility on objects such as Strong trees and Rocks, or even scale walls. Grapples are wielded in the arrow slot and used with a crossbow. Sometimes grapples may break (although rare) so it is a good idea to have more than one available.
Level 59 smithing is required to smith the mithril grapple tip from mithril bars. Each tip is made from one bar. Level 59 fletching is required to attach the tips to mithril bolts. Finally a rope is used on the unfinished mithril grapple to make a complete mithril grapple, usable with grapple shortcuts. Grapples are tradeable at every stage of construction. Making a mithril grapple tip grants 50 xp.
Although the level on the left is the required Ranged level, grappling also requires Agility and Strength (listed in parentheses with the obstacle).
