To be honest i finished the game without using the special ability - to the end i didn't mention the new skill in my use bar - to the end i thought i have to escort the zeppelin to the citadel and there the zeppelin will use the special attack gained from Belegar( or from the bad wizard ). When i done the escort the zeppelin was on 2-3 hits from crash (on very low health i mean). After i finish the game i decide to explore the flying fortresses field a bit more - just for fun and then i realized for what exactly is the unknown ability in the use bar
With it everything was completely different for me - the fight was easier. My opinion - if i could finish the quest without the special skill you have to can do the same easier with it, but if you are so desperate i gladly will send you the last autosave i have
