Sirene's Dress is an optional location in Clair Obscur: Expedition 33 that is on the east side of the Sirene island. While players are free to visit this map as soon as they can reach its entrance portal, they may find that the path within it is blocked by a door. This guide is here to help players get past that door, and it details every item that can be found on the Sirene's Dress map in Clair Obscur: Expedition 33.

For those players who want just a small push in the right direction, it may be enough to say that Sirene's Dress is directly connected to one of Lune's relationship events.

How to Enter

As previously mentioned, the entrance portal to Sirene's Dress is on the east side of the island with Sirene, and its position has been marked on the map that is above. However, before players pass through that portal, they should make sure to initiate Lune's Level 6 relationship event, which centers around the location. For the uninitiated, relationship events in Clair Obscur: Expedition 33 can be started by interacting with a character at camp, and opting to "spend time" with them, and Lune's Level 6 event can be pursued after beating the game's final boss.

Once Lune's Level 6 event has begun, players should enter Sirene's Dress and interact with the large door that is just beyond the expedition flag. Players should then choose "playing music," and they will be free to continue along the path after a brief cinematic sequence.

Chromatic Glissando

As players proceed down the path, they will run into the map's main obstacle: the Chromatic Glissando. While this enemy should not prove very difficult for players who have gotten their Clair Obscur: Expedition 33 party members to reasonable levels, as its attack patterns are quite straightforward, here are some tips that may prove useful:

  • The Chromatic Glissando has a weak point at the tip of its tail, and destroying it with Free Aim will reduce the power of the enemy's tail-based offense. The Glissando can regenerate its tail, though, and players may need to destroy it several times.
  • It is critical that players prioritize keeping their party members healthy, as the Glissando will heal itself by consuming characters when they die. While Healing Tints may be enough to keep the party members alive, players may want to consider bringing some healing skills, like Lune's Revitalization, to the fight.
  • The Chromatic Glissando spawns three floating enemies when defeated. One of the easiest ways to beat those foes is to hit them with big counterattacks, which can be achieved by equipping party members with the Painted Power and Augmented Counter Pictos/Luminas.

Upon defeating the Chromatic Glissando, players will receive the following items:

Expedition 46 Journal

Players who follow the path beyond the Chromatic Glissando's arena will run directly into the Expedition 46 journal. After collecting that journal, players can return to the beginning of the map and pass through the portal to trigger the conclusion to Lune's Level 6 relationship event.
