Fall Damage

Fall Damage is the physical damage one sustains from falling a certain distance, not to be confused with the damage from falling objects. Typically, a character sustains 1d6 damage per 3m of fall, to a maximum of 20d6, though this can change based on execution, gravity and surface.

Execution of Fall
If the character deliberately jumped the distance, the damage is the same, but the first damage die is non-lethal damage. If a DC 15 Acrobatics check is passed, the first damage die is ignored and the second damage die is non-lethal damage. The two effects (if a character was to jump deliberately and succeed the acrobatics check).

Effects of Gravity
The following table can be used to calculate the effects of a planet's gravity on fall damage: NB: The above values are for falls only. If extra acceleration is added, the damage may well increase.

Surfaces
If landing on a soft surface, such as mud, take the first damage die in non-lethal damage. If landing on a very soft surface, such as a bale of hay or a large mattress, the first die of damage is ignored and the second is non-lethal. These stack cumulatively with the damage reduction from the execution of the fall.

If landing in water (or another, similar liquid), the rules are slightly different. Provided the water is at least 3m deep (less on lower gravity worlds, more on higher gravity worlds), the first 6m of fall provide no damage, the next 6m deal non-lethal damage and any subsequent falling deals normal, lethal damage.

If diving into water and a successful DC 15 Swim check is made, for every 3m of depth, 9m of damage is not dealt. However, for every 15m of fall, the swim DC is increased by 5.
