When you fall, you take 1d6 falling damage per 5 feet fallen. You may attempt to break the fall to reduce this damage.
Drowning and SuffocationEdit
If you cannot breathe, you must make an Endurance check (no DC) to determine the number of seconds that you can hold your breath (divide this by 5 to determine the number of turns during an Encounter). Once this time runs out, you begin to take 1d6 suffocation damage per turn.
Certain effects, such as heat stroke and exhaustion, will deal 1d4 fatigue damage to you over a regular interval.
