Environment

Difficult Terrain

The ground is considered to be Difficult Terrain when it would provide significant obstruction to movement - viscous mud, rocky or uneven terrain, soft sand, piles of bodies, bones, etc. Where it would normally take 1 yard of a character's base movement speed to move through a square, it will cost an additional movement speed to move safely through Difficult Terrain.

Falling

Unless otherwise specified falling damage deals 1d10 per Yard fallen. If the fall is equal or less than 3 yards this damage is Non-Lethal, however falls for a longer distance deal Lethal damage instead.
