Utilize Skip Travel to Get Origin Metals

Since you have to travel throughout the whole Aionios to get Origin metals, it'd be more efficient to move by Skip Travel to those places as close as possible.

Chapter 7 Boss Battle Strategy

Preparation For Boss Battle

Change the Classes of Party

In the middle of Boss Battle, your party will split into Team Keves and Team Agnus. It is possible to win even if the classes are unbalanced. But it'd be better to organize each teams with the combination of Attacker, Healer and Defender. Make sure you changed the classes before starting the Boss Battle.

Team AgnusMio, Taion, Sena

Hints for Defeating Z

Defeat Z(Lv72)
Click to Enlarge

The Power of Ouroboros will be sealed

Power of Ouroboros are sealed
Click to Enlarge

In the battle against Z, Chain Attack and Interlink will be disabled. Reducing over 20% of Z's HP will trigger an event that makes Interlink Pairs able to activate Chain Order set by set. From then on, they can attack using the power of Ouroboros.

Final Lucky Seven causes large damage

While the power of Ouroboros is sealed, it is recommended to use the Talent Art "Unlimited Sword". Keep shooting Tachyon Slash in front of Z, then activate "Final Lucky Seven" to cause a large damage when the gauge of Talent Arts is full.

Hints for Defeating X and Y

Defeat X and Y
Click to Enlarge

Split into 2 teams to fight

In the battle against X and Y, the party will be split into Team Agnus and Keves (the heroes are in the team they belong), that makes Interlink disabled. Chain Attack could be the main method of attack and recovery, use it actively!

Event triggered while defeating X

When X's HP is reduced beyond a certain level, he will perform an attack to reduce your party member's HP to 1. However, there is no need to panic because an event will be triggered and HP will be fully recovered after then.

Hints for Defeating Z Infinity (2nd time)

Beware of the attack after event

Origin Punishment
Click to Enlarge

An event occurs when Z's HP is reduced to about 60%, after then he will perform an attack "Origin Punishment". It will reduce all the party member's HP 60% and put them in a Daze state. Be prepared to recover HP.

Beware of the total attack of "Infinite Finale"

Evade all the attacks
Click to Enlarge

▲When "Infinite Finale" is shown at the top of screen, it means he is going to attack after evading all the attacks from your party.

Infinite Finale
Click to Enlarge

▲Performs a random total attack.

The random total attack "Infinite Finale" is the most alarming attack in the battle against Z Infinity. If the healers are incapacitated, the situation will become much worse.

It is a sign when all our attacks are evaded. Make preparations for the coming attack, like "becoming invincible through Interlink", "using Chain Attack to recover while being attacked" and "recovering in advance to survive the attack".
