Yeah, I envision the fighty version being a mount for a skink chief instead of a saurus hero. But to bring the thread back on topic, here's how I see the Steg-bomb. A Steg-bomb can only be carried by two coatl. The steg in question does not have the usual howdah weapon selection. Instead, the howdah is fitted with a gliding apparatus, and the skink crew operate the controls by adjusting ropes and pulleys. This allows the steg to be more accurately guided to its target. If the steg lands on a unit, that unit suffers 3d6 impact hits at strength 5. The steg then continues its path and is placed in close combat with the unit landed upon. Also, at any time afterward, if the stegadon is not engaged in close combat, a unit of 2 coatls (or 4 terradons) may hoist the stegadon aloft once more by flying over it. The stegadon bomb may then be dropped again as normal.
