Travel Pace
- Fast — 4 mph / 30 miles/day
- −5 penalty to passive Perception.
- Normal — 3 mph / 24 miles/day
- No penalty.
- Slow — 2 mph / 18 miles/day
- Can use stealth while traveling.
Difficult terrain (dense forest, deep snow, rubble) costs 2 feet of movement per foot traveled — effectively halving pace through it.
Light and Vision
- Bright light
- Normal vision.
- Dim light
- Lightly obscured — disadvantage on Wisdom (Perception) checks relying on sight.
- Darkness
- Heavily obscured — creatures effectively suffer the blinded condition for sight.
Darkvision lets many races see in darkness as dim light (disadvantage on Perception) out to a listed range — but only in shades of gray.
Food, Water, and Forced Marches
A character needs 1 pound of food and 1 gallon of water per day (half for Small characters). Foraging with a Wisdom (Survival) check can cover this in the wild. Pushing beyond 8 hours of travel in a day forces a Constitution saving throw (DC 10 + 1 per extra hour) — failure gains one level of exhaustion.
