In the realm of Clair Obscur: Expedition 33, Sirène stands out as a pivotal boss you must defeat to progress the storyline. As one of the two Axons charged with guarding The Paintress, your encounter with her will occur either right before or immediately following your battle with the Visages and the Mask Keeper, as you approach the climax of your approximately 30-hour expedition.
Sirène presents a formidable challenge, comprised of three distinct phases that will test your skills in combat. However, with adequate preparation, precise dodging and parrying techniques, coupled with the guidance provided here, you will be well-equipped to emerge victorious.
Let’s dive into the preparation required to face Sirène successfully.
Preparation for Battling Mermaid
While Sirène’s captivating dance moves may initially seem daunting, the right combination of team members and skills will enable you to conquer her. She has been a significant figure in your journey, and if you’ve reached this stage, you possess the necessary tools for success.
Ensure you have conquered Tisseur, an optional boss prior to meeting Glissando, to acquire the Anti-Charm Picto. This item is crucial for your battle against Sirène.
Optimizing Your Party Composition
Many players, myself included, favor a party setup of Verso, Sciel, and Maelle, which proves highly effective against Sirène. Notably, Sirène has a weakness to Dark attacks, making Sciel’s robust Dark skills an ideal choice for this encounter.
Verso’s Perfection mechanic also allows for significant damage output while providing essential support skills, ensuring he remains a valuable team member. If you have mastered Maelle’s Virtuose Stance, she can inflict substantial damage as well, rounding out your team effectively.
Recommended Skills for the Encounter
As you are now deep in the mid-to-late game of Clair Obscur, you likely possess numerous helpful skills that can be strategically adjusted for this particular battle. Focus on Sciel’s powerful Dark abilities, especially those that can build Foretell on the enemy.
Utilizing Sciel’s skills effectively will allow you to enter Twilight and unleash high-damage moves that consume Foretell. Below is a breakdown of suggested skills for each party member:
|

Consider equipping Twilight Dance for Sciel, but be mindful of using multiple skills that consume a high amount of AP points in this intense battle.
Both Twilight Dance and Final Path can excel in dealing Dark damage, though their high AP costs may limit your ability to utilize both often; choose your preferred option based on your strategy.
Understanding Sirène’s Attack Patterns
Sirène’s complex battle design involves more phases than most bosses, showcasing three increasingly aggressive attack patterns you’ll need to navigate. Below is a detailed breakdown of her attacks during each phase:
Phase One Breakdown
Sirène won’t hold back in her opening phase, delivering hefty damage if you’re not prepared with your defensive maneuvers. I recommend prioritizing dodges over parries due to the unpredictable nature of her attacks. Here’s a summary of what to expect:
|
Attack Phrase Indicator |
Description |
Player Action |
|---|---|---|
|
“Mermaid dances with the Glissandos.” |
Sirène unleashes two Glissando worms, hitting the whole party upon impact. |
Dodge the attacks consecutively |
|
“Mermaid seduces (party member).” |
A party member is entrapped by ribbons, incurring massive damage, and suffers Charm status. |
Perform a Gradient Counter right away |
|
“A widow Ballet Charms (party member) and flies away.” |
A widow dancer targets a member and launches an energy ball that deals damage and charms on contact. |
Dodge right before the energy ball reappears for the third time |
|
“Sirène attacks with her dress.” |
Sirène throws strands of fabric at each party member in sequence. |
Dodge all three attacks |
Phase Two Overview
Transitioning to Phase Two occurs when Sirène’s health dips to approximately one-third remaining. This shift is marked by the phrase “Sirène’s dance becomes frantic.”In addition to her previous attacks, she will introduce new moves:

Jump over the shockwave, then perform a jump-counter. Dodge the widow dancer’s attack. Repeat twice. |
Strategies for Defeating Sirène
Setting yourself up for success against Sirène hinges on equipping the Anti-Charm Picto/Lumina across your entire party. Given her capacity to charm teammates, this step is essential. After acquiring the Anti-Charm from the Tisseur encounter, equip it on one character to maximize its effectiveness in upcoming battles.
Without the charm ability, Sirène becomes significantly easier to manage, and you can then focus on mastering the timing of her other attacks for dodging, parrying, and jump-countering.
The key to victory lies in applying and consuming as much Foretell with Sciel’s Dark skills as possible. This strategy will help rapidly deplete Sirène’s HP. Once you trigger Twilight mode, your offensive capabilities will increase exponentially.
Utilizing Maelle’s Degagement skill will inflict Fire weakness upon Sirène, followed by massive Fire damage to take full advantage of her vulnerability.
Transitioning Maelle into Virtuose Stance via Burn effects from Pyrolyse will allow you to unleash high-damage moves through Fleuret Fury, maximizing your damage potential.
During this encounter, Verso will primarily assume a support role, contributing significantly by keeping the party’s HP stable with Perfect Recovery and removing adverse Curse effects. His Marking Shot skill prepares Sciel or Maelle for a powerful follow-up, while End Bringer lets him deal damage when an opening arises.
By remaining vigilant, executing well-timed dodges and parries, and skillfully combining Sciel’s Dark and Maelle’s Fire attacks, you can achieve victory against Sirène.
