As we all know, Air Buster takes 5x normal damage from behind (= the side he didn't attack last turn) and, sometimes, we want to remove this. This data is stored in the scene.bin (Formation tab). Air Buster is considered as a "Third Side attack" by PrC and is the only enemy (As far as I know) that calls that formation. I cannot test it right now because I don't have any save nearby, but soon I will have one... I hope. I think this is as easy as changing this formation to remove that stat from Air Buster. Maybe a random encounter can have this too...
