With the Climb Skill the character can ascend or descend ropes, pipes, scaffolding, and both natural and man-made walls. This Skill is not used for ladders or other easily ascended ways, but for climbs without ready handholds or other poor climbing conditions. The condition of the surface or item and the environmental conditions can impose additional bonuses or penalties. It is far more difficult to ascend an icy rock face in a blizzard than the outer shell of a hive that is crisscrossed with pipes and conduits. A successful test allows the character to ascend or descend at one-half his half move rate. See Climbing in Chapter VII: Playing the Game for more details.
