How to Beat Siren

[1] Use Thunder Attack.

Siren is weak to thunder elemental attacks. Use them immediately to maximize the party's damage and to stagger Siren as fast as possible. Staggering her early limits how much damage she can do to the party.

[2] Use Pray to Cure Charm Ailment.

Whenever Siren casts Allure, it will inflict the Charm status ailment, causing the party to attack each other at random. This can quickly throw a fight into chaos by wasting turns and dealing unnecessary damage. To counter this, use Fina's Pray to remove the status ailment on your party.
