Leaves and sticks crackle and crunch under the player's feet as they walk along.
A Survival or Knowledge (Nature) check of DC 15 will note that this area has recently seen localized flooding from rain and may be muddy.
If the party is so forewarned, they gain a +4 insight bonus on Acrobatics checks to avoid stepping in thick mud (DC 10) as they cross. Any characters that fail the check will become stuck in the mud. Until freed, they gain the grabbed condition. Characters can be freed with a Strength check of DC 15 made by them or another party member. If more than one person helps pull, add +2 for each helper to the roll. There is a 25% that a shoe or boot is not freed with the characters. Another strength check of DC 15 is required to rescue any lost footwear. Barefoot characters treat all natural terrain as difficult terrain.
