Terrain Difficulty | Range | Descriptive Examples |
---|---|---|
Very Easy: | 1-5 | Flat, clear, even ground with no obstacles. Clear walkways or tracks. For swimming, calm water. |
Easy: | 6-10 | Flat but naturally uneven ground (fields, yards) that may have a few small obstacles such as rocks, holes, bushes, low branches, and so forth. For swimming, water with minor obstacles: occasional branches or reefs, or water with mdoerate currents. |
Moderate: | 11-15 | Rough ground or any area with many obstacles (large holes, rocks, thickets and bushes). For swimming, an area with many obstacles or a very confined area, such as a small tunnel |
Difficult: | 16-20 | Running through a densely packed area that's difficult to navigate: a panicked crowd or a thick forest, for example. Very rough ground with drop outs, darkened tunnels, or an area that's being pelted by falling boulders. Swimming during a very rough storm or around attacking predators. |
Very Difficult: | 21-30 | Moving through any dangerous terrain, such as a minefield, down a narrow crawl-way with whirling cooling fans, a starship as it breaks apart, or along the outside of a repulsorlift vehicle as it makes twisting maneuvers. Swimming in the middle of a dangerous storm with large waves. |
Heroic: | 31+ | Heroic terrain is virtually impassable: running through an avalanche, or running down a corridor filled with falling debris, smoke, and exploding consoles. For swimming, in the middle of a tidal wave or hurricane. |
