This mega boss has two attacks like the previous three: a bullet that deals great damage and produces 15 clouds which deal additional damage, and 2 freezing spears which are shot at fixed angles, have enough range to cover the entire screen, and reflect off terrain. The bullets can be deadly for melee characters if they cannot dodge the bullet on time. As with the Submarine Shrine Boss, Freeze Charms are strongly recommended. A way to beat this boss is to use the Dodge strategy with any character with high enough DPS, such as a Boxer or Angel. However, both melee and ranged characters run into some kind of obstacle; Melee characters must be careful around the bullets, as they deal massive damage. On the other hand, ranged characters must constantly dodge the freezing arrows. A Knockback's Card 4 on a Sniper or a Magician with a Thunder Orb can be helpful to keep the boss at a great distance, so that players only need to think of dodging the arrows, which have nearly identical paths as the boss is cornered by the knockback effect. Unlike other mega bosses, this one is almost completely immune to Ice attacks. Thunder and Poison type weapons are best against this boss, especially the Sniper's Indra Arrow 6 and the Boxer's Poison Claw 5 with a high-level Peridot.
This is the first mega boss to have another immunity besides Freeze.
This is the first mega boss not to have a fire attack.
This is the first mega boss that doesn't drop any cards, thus the first megaboss to not drop a level of the Vampire's Card.
This megaboss's battle has a much different feel overall than the previous three. The previous megabosses have an attack that are generally ignorable and another dangerous attack that is more threatening. This megaboss however, fills up the entire room with a fairly dangerous attack which are not focused on specific characters until they get too close, where the boss will start using the bullets.
