The grapple path is much much faster than the dexterity path, needing just 3 barriers to be bypassed - all grapples. A crossbow and also mithril grapple is needed to pass this course, as well as it is feasible to shed the grapple whilst training, so if you use this route, bring a number of grapples. You obtain Ranged experience for utilizing this course, and a small amount of Agility experience.
