Terrain
The terrain through which you travel affects the distance you can cover while traveling. The table below shows you how to modify travel times based on the type of terrain and the quality of the path you’re following. A highway is a major, mostly straight, paved road. A road is typically a dirt track. A trail is like a road, except that it allows only single-file travel and does not benefit a party traveling with vehicles. Trackless terrain is a wild area with no paths.
| Terrain | Highway | Road or Trail | Trackless |
|---|---|---|---|
| Desert (all temperatures) | ×1 | ×1/2 | ×1/2 |
| Forest (typical) | ×1 | ×1 | ×1/2 |
| Forest (dense) | ×1 | ×3/4 | ×1/4 |
| Hill | ×1 | ×3/4 | ×1/2 |
| Marsh | ×1 | ×3/4 | ×1/2 |
| Mountain | ×3/4 | ×3/ 4 | ×1/2 |
| Plains | ×1 | ×1 | ×3/4 |
| Urban | ×3/4 | ×1/2 | ×1/2 |
