All his Dyne skills are related to his weapons, so i suppose that does relate them to his SKill skills, yes. On my first try i never bothered to learn Detect but the Dyne skill (Tidal Flame?) is handy for when you face the first Waltz. I never really thought about all this...

Oh yeah, I never use Grand Lethal, it wastes magic, i use Solution 9 and the one before it (If you know tell me plz)cos they both do 9999, it happens about lvl 45...I think. Correct me if I'm wrong.
