Marsh

Source Ultimate Campaign pg. 157
Marshes, swamps, and bogs are challenging ground to traverse. Survival check DCs to avoid getting lost increase by 1 in a marsh hex.

Difficult: A difficult marsh hex is a deadly place, replete with quicksand, poisonous plants, and treacherous water. The DCs for Survival checks to get along in the wild increase by 5. For the purposes of travel and exploration times, treat the party’s speed as one category slower on Tables 3–2 and 3–3.

Feature: The hex might be the location of a marsh creature’s den (such as a hag), a sunken ruin, a large water causeway, or a shallow lake.

Hunting Ground: Attacks in this hex are equally likely to come from underwater as from the surface. The chance of random encounters increases by 25%.

Resource: Marsh resources primarily come in the form of medicinal plants and herbs.

Secret: Unfortunate explorers died in the marsh and left behind all their gear. With a successful DC 25 Survival check, the PCs can each salvage equipment worth 10 gp per character level.
