Playstyle Guide & Rotation

Pyrois is a very unique but easy to use Agent in the game, being designed as a character that new and returning players can use as a powerful Ether Damage dealing Agent in various contents in the game.

Pyrois’ skill kit and gameplan is relatively simple in nature: Upon attacking enemies, Pyrois will deal Ether damage to enemies and accumulate Kinetic Energy. Once they have accumulated enough Kinetic Energy, they will be able to use their EX Special Attack to deal Ether damage to enemies and raise their Decibel quickly, allowing them to trigger their Ultimate.

Pyrois’ Ultimate is extremely unique as it allows players to choose 1 out of 4 different effects and attacks to trigger upon using an Ultimate, with each Ultimate fulfilling a different role and help to trigger a different effect upon usage:

– Ultimate 1 (Up): Allows Pyrois to unleash 2 slashes of enhanced basic attack forward, dealing Ether damage to the enemies. Then enhances the damage output of Pyrois’ basic attacks against Dazed enemies for a period of time.

– Ultimate 2 (Down): Allows Pyrois to deal a big instance of Ether Damage surrounding them. Then gains an Energy Regen effect and massively enhances Pyrois’ defensive ability.

– Ultimate 3 (Left): Allows Pyrois to charge up and unleash a forward slash, dealing damage to enemies. Then gains an effect that allows Pyrois heavy attacks to deal additional damage to enemies.

– Ultimate 4 (Right): Allows Pyrois to summon a black hole and constantly deal damage to enemies in an area. The Pyrois gains the ability to trigger the Totalize effect when hitting enemies with heavy attacks, dealing powerful damage to them and ending their Daze state early.
