Grapple

Mountains are a really annoying problem for every traveler, being that they are impassable.... normally. But with the right equipment, this is no problem at all. With a Grapple, it is easy to climb over the mountains in question, with only the highest peaks still impassable. Of course there is always the danger of falling, if the traveler isn't skilled enough with the Grapple, but that is the price for a shortcut.

The Grapple was seen and absolutely essential in Ultima V. After hearing rumors in Buccaneer's Den, the Avatar asked Lord Michael of Empath Abbey for the Grapple. Only with it, the quest could be completed.
