Playstyle Guide

Kamui: Aeternion’s gameplay revolves around his ability to switch between 2 different weapons to accumulate his special points while dealing damage to enemies. His powerful and smooth combo allows him to juggle the enemies in the air and allow him to perform both aerial and ground combos to the enemies.

Upon entering the battlefield, Kamui: Aeternion will be in his normal mode, where players are able to use his Blue Orbs to deal damage to enemies and accumulate his special Core Passive points. In this guide, Kamui: Aeternion is able to parry enemies’ incoming attacks with his shield. Upon accumulating enough points, players can switch him into his broadsword mode using his yellow orb.

Upon entering his broadsword mode, all of Kamui’s attacks will be enhanced based on the amount of his Core Passive points and will be able to use Red Orbs. Upon consuming Red Orbs, Kamui: Aeternion is able to deal powerful attacks upon enemies, launching them into the air and accumulating special stacks of attacks. Once his stacks are full, holding his dodge or his basic attack button will allow him to deal powerful constant attacks to enemies, devastating them and accumulate Signature Move energy.

Once his Signature energy is full, Kamui: Aeternion can unleash a powerful slash of energy towards enemies, dealing powerful Fire or Plasma Beam damage to enemies.
