When a character is knocked across the rim of elevated terrain (i.e.: from a higher elevation to a lower elevation (see Line of Fire: The Rim, p. 14), the knock back path ends in the first square of a lower elevation and that character is dealt 2 knock back damage. If the first square of a lower elevation along the knock back path is not able to be occupied, the knock back path ends in the last square of the higher elevation and that character is not dealt knock back damage. Characters using the Flight ability (see the Powers and Abilities Card) which are knocked back off of elevated terrain are not dealt knock back damage, though they still end their knock back path in the first empty square of a lower elevation.
