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 directly underneath it with any character with high enough DPS, such as a Boxer or Angel, while the ranged characters support it from the sides. 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 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, Fire, and Poison type weapons are best against this boss, especially the Sniper's Double Flame 6 and the Boxer's Poison Claw 5 with a high-level Peridot. An ONIGIRI's Card can also be incredibly useful for fast attackers by spawning large amounts of Onigiri for constant LP recovery, reducing the need for revivals. A Vampire's Card is also useful. High-arc type weapons such as Missile 5 and the Indra Arrow 6 may struggle to hit this boss as they will hit the ceiling of the area where this boss resides.
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 weak and easy to ignore, 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.
