Hah, sorry, I can't continue the conversation format. None of the three warrior "Crash" skills work on super defense up. There's a difference between super defense up and normal attack/magic/defense up. The normal buffs are the ones that put a small icon of a sword/sun/shield above the monster, respectively. Skeles cast these a lot, try Power Crash out on them. Dragon Knight: Power Crash dispels attack up White Knight: Magic Crash dispels magic up Crusader: Armor Crash dispels defense up
