How to Beat Sirene (Boss)

Be Prepared for Charm

Tisseur Anti-Charm Loot

Throughout the boss battle, Sirene will constantly send a Ballet out to Charm a single target. If its attack lands, it will inflict the aforementioned status effect that forces the target to act on its own and attack the party.

To prevent this, equip the Anti-Charm Picto and Lumina on your characters to protect them from the status, or have effects like Cleansing Tint on hand to remove the status.

All Status Effects Guide

Grand Ballet Signals Special Attacks

Sirene Grand Ballet

Sirene will execute special attacks whenever a new part of the Grand Ballet begins. These are more powerful than her usual attacks, and should be avoided or parried to prevent taking too much damage.

Use Ice and Dark Elements

Sirene Ice Weakness

Sirene is weak to the Ice and Dark elements, so use weapons and attacks of these types to expedite the fight. Lune and Sciel specialize in these elements, and can be used as damage-dealers against Sirene.

List of All Characters

Sirene (Boss) Attack Patterns

Grand Ballet Begins

The Grand Ballet begins, and Sirene summons five Ballets to hit the party 5 times. Dodge as each Ballet lands to the right of the party, and delay the last dodge a bit as the final Ballet stalls before striking.

The Final Act

The Final Act begins, with Sirene summoning a Glissando and Ballets to attack the party 7 times. Jump Evade the Glissando's attacks shortly after the Jump Flare appears, and dodge the Ballet as it appears to the party's right.

These two will alternate thrice, before you will have to dodge one final strike from Sirene. Dodge as she brings her arms down to slam the party.
