Hi, you add scaffolding for building but we need climbing belt in the game. We go up from the bottom with scaffolding but we some times we have to come down from above. For example deep mines, high-rise building construction, steep-sided mountains. We can fasten the belt around our waist and secure the rope to any block. The rope has a specific length, and we can move up and down as we please along it. Once we reach a safe area, we can resecure the rope and descend again. Thank you
