Yeah, Gadlight is probably the only tough boss in the game, he has the move twice as one of his skills. You'll get to kill him for good in about 9 more chapters I believe.

Are you sure he's only able to move twice? He's got a skill that seems exclusive to him with a 3 on it and the fucker moved and attacked twice with that 4-10 range move that actually isn't Post-Move but just ALL. I think the sob has 3 actions. I just made him retreat on the 3rd turn of chapter 49 but goddamn did that take a lot of effort and ignoring the mooks he brings.

Actually, I think you're right about him being able to move three times. (Been a while since I saw his skill list) I believe the other bosses have the move two times ability.
