Catfall is a physical, exotic advantage that subtracts five yards from a fall
automatically and allows a DX roll for half damage. (Basic Set 41)
Referenced in Dungeon Fantasy 12: Ninja™, pp. 5 and 7, as a ninja ability, and GURPS Powers™, p. 43, which adds the new special enhancement, Feather Fall, and the new special limitation, Parachute.
