Omur what is your patk unbuffed? Is your gear rofl red and is it stated 3 str str 3 dex dex or 5 dex dex 1sta dex? That might be the reason your damage could be lower than you expected, 3tr str 3dex dex is about 200-300k more patk fully buffed than 5dex dex 1sta dex and that is a ton of damage lost
