Difficult Terrain

Source GM Core pg. 37 Spring 2026, 1st Printing
Difficult terrain such as thick undergrowth usually slows down progress. Unless it’s important how far the group gets in a particular time frame, this can be covered with a quick description of chopping through the vines or trudging through a bog. If the characters are on a deadline, adjust their progress on the Travel Speed table (page 36), typically by cutting it in half if almost all of the land is difficult terrain or to one-third for greater difficult terrain.
