Difficult Terrain (Rules) (GM Core)

Difficult terrain can slow progress during overland journeys but rarely lasts long enough to impact interstellar voyages. 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, trudging through a bog, or piloting through prolonged turbulence or a Drift storm. If the characters are on a deadline, adjust their speed on the Travel Speed table (Travel), typically by cutting it in half if almost all the land is difficult terrain or to one-third for greater difficult terrain.
