Armachthys

An Armachthys is a monster found in the Underwater Temple in ALfheim Online.

Appearance
An Armachthys is a large. black with a large gray spot fish that has a pair of large fins in its front, three more pairs of fins on its bottom side, with the last pair being larger than the first two, and two more large fins on its top side. The monster's head is covered is tough bone armour with a horn sticking out of its top. There is a small opening in the armour at the top of its head which may be its weak point. The monster has two bright red eyes and sharp teeth with two large fangs at the center of its jaw.

Abilities
Due to the monster’s armoured head, it is practically impossible to harm him from the front. The monster usually attacks by charging at its opponent and ramming them with its armoured head, but it may also start swimming fast in circles to form a whirlwind.

Extra Edition
An Armachthys emerged from a trap in the Underwater Temple after Kirito and Klein accidentally fell into it and barely managed to swim out of it. Kirito tried to attract its attention while Klein, Agil, Silica and Lisbeth attacked it from the sides while it was busy and Asuna and Leafa supported the party with magic. However, in the midst of the battle, Leafa decided to join in on the fight and triggered the Armarchthys to activate its whirlwind ability that sucked in Leafa and made her almost fall into the trap. While the monster was still maintaining its whirlwind, Kirito used its force to reach the ceiling and attack the monster from the top, killing it with a hit at an opening in its armour.
