A Path to Steam
You can always keep your footing, no matter how narrow the walking surface, under normal conditions. This lets you walk along a tightrope, ledge, tree limb, or other anchored
surface without having to make a die roll. If the surface is wet, slippery, or unstable, you get +6 on all rolls to keep your feet. In combat, you get +4 to DX and DX-based skill rolls to keep your feet or avoid being knocked down. Finally, you get +1 to Acrobatics, Climbing, and Piloting skills.
