This boss can be troubling due to its very high LP and its powerful attack. It shoots a very large Bullet that deals massive damage, and explodes on contact with a solid surface or character, which launches 9 clouds in a spread similar to that of a Gunner's Bazooka 2. If a character gets hit directly, it will take between 110-220 damage. The boss also has numerous Grey Mask Fish and Grey Big Mask Fish surrounding it, so the large amount of enemies might also be a problem. The boss only attacks if a character is close; however, the bullet will usually go across the screen. A Hit and Run strategy might work well against this boss, especially with a Thunder type weapon, as this boss is weak to Thunder, much like its smaller cousins. A Magician's Big Thunder 3 (assuming the player survived Mist Grove 2 to get it) with a Topaz and a Catapult's Card combination may also help due to this boss's weakness to Thunder and the Big Thunder's large amount of damage. If a player does not have one, the Magician's Thunder Storm 2, the Priest's Lightning Staff 2, and the Boxer's Poison Knuckle 3 (with a Peridot) will make short work of the boss. Swinging a melee character around it can cause the boss's attack to go in a different direction, allowing players to gain an advantage on it. It also helps to apply the dodge strategy if this boss's minions are defeated.
