If a space is Difficult Terrain, every foot of movement in that space costs 1 extra foot. For example, moving 5 feet through Difficult Terrain costs 10 feet of movement. Difficult Terrain isn’t cumulative; either a space is Difficult Terrain or it isn’t. A space is Difficult Terrain if the space contains any of the following or something similar: • A creature that isn’t Tiny or your ally • Furniture that is sized for creatures of your size or larger • Heavy snow, ice, rubble, or undergrowth • Liquid that’s between shin- and waist-deep • A narrow opening sized for a creature one size smaller than you • A slope of 20 degrees or more
