Korg begins the fight with 9 Rock Shield charges which are removed each time he is struck. An additional charge is removed when Korg’s Dash Attack is interrupted by a Light Attack and if Struck by a Special Attack 3, all Rock Shield charges are removed instead.
While Rock Shield is active, powerful enemy attacks cannot deal more than 40% of the opponent's Attack Rating in a single hit. Special 3 Attacks cannot deal more than 120% of the opponent's Attack instead.
When all charges are consumed, Rock Shield is shattered and it takes between 11 and 15 seconds to reform. Each time Rock Shield reforms it starts with 1 less charge.
