In regards to the mutation Wings does the mutant suffer falling damage?
Yes. If a fighter is shot off a ledge then he will suffer damage per the Falling rules on page 27 of the ORB. Also, keep in mind if you are shot while moving and you were in the air then you will fall the distance to the level directly below you. This means if you were attempting to fly from a three-story building to the ground and are shot as soon as you step off the edge and are hit, even just pinned, you would fall 9″ to the ground and suffer one strength 9 hit causing d6 wounds.
