This proficiency when unlocked allows a character to ascend or descend steep, rocky terrain by using spikes, grappling hooks, and other tools that he or she drives into cracks in the rock face, or however other way they're used, thereby being able to negotiate a surface that is not normally able to be climbed. The following types of wall surfaces can be climbed with this method: Sloping wall (40-55 degree slant), straight tree/pole/rope, tree with branches, rope and wall, and ice wall. Characters with this proficiency will be able to climb as fast as thieves.
