The Environment



When you fall from a great height you instantly descend up to 100 units per turn. A fall from a great height is one of the most common hazards facing an adventurer. At the end of a fall (more than 2 units tall), a creature takes 1d4 bludgeoning damage for every 2 units it falls to a maximum of 20d4. The creature lands prone, unless it avoids taking damage from the fall.


A creature can hold its breath for a number of turns equal to 1 + twice your endurance (minimum of 2)
When a creature runs out of breath or is choking, it can survive for a number of rounds equal to its Endurance (minimum of 1 round). At the start of its next turn, it drops to 0 hit points and is dying, and it can't regain hit points or be stabilized until it can breathe again.

Difficult terrain

you spend 2 units of movement for every 1 unit while in difficult terrain.
