You can reduce the effective speed with which you fall if you are within arm's reach of a wall.
Prerequisite: 5 ranks in Tumble, +3 base Reflex save.
Benefit: You can use a nearby wall to slow the speed at which you fall, reducing your damage from velocity by 2d6 for every +1 base Reflex save. As hitting the ground after reaching terminal velocity causes 18d6 damage, a character with +9 base Reflex save can fall any distance safely as long as they are within arm's reach of a wall.
