Find and replace yours safely.Free scan · under a minuteFive encounters appear under the dedicated hidden-boss list for Clair Obscur: Expedition 33: Chromatic Chapelier, Clea, Simon, Alicia, and Chromatic Clair Obscur. Their unlocks range from shooting every crow in an area to finishing a character quest or returning after the Paintress fight. This guide covers those five named encounters—not every optional boss in the game. The source guide, last updated December 19, 2025, has an inconsistency: its introduction says there are three secret bosses, but it lists five entries. Game8’s guide hub also includes Patch 1.5.0 content, so this is a defined list rather than a claim that no other optional encounters exist.
Secret bosses at a glance
| Boss | Where and how to unlock | What to know in the fight |
|---|---|---|
| Chromatic Chapelier | The Crows, west of Visages. Swim there with Esquie, then shoot every crow in the area. | Resists light and dark; its revolving masks can silence party members. |
| Clea | Flying Manor, in Act 3. Reach it with Esquie’s flying ability, complete all four trials, then enter the door ahead of the trials. | Parry and counter successfully; missed opportunities heal Clea. |
| Simon | The Abyss, while exploring Renoir’s Drafts. Enter the opening at the glowing pillar, continue to the cliff, and drop down. | Described as one of the game’s most challenging secret fights; build up each character before attempting it. |
| Alicia | The top of The Reacher. Begin Maelle’s Level 7 relationship quest. | A one-on-one fight between Alicia and Maelle. |
| Chromatic Clair Obscur | After defeating the Paintress, return to the Monolith and make your way to the top again. | The available guide information establishes the unlock and location, but not a specific combat tactic. |
Locations, unlock steps, and the mechanics summarized here are from Game8’s hidden-boss guide. It does not provide reliable level recommendations, full attack sequences, or tested builds for all five fights.

How to find and handle each boss
Chromatic Chapelier: shoot every crow in The Crows
Travel west of Visages and use Esquie’s swimming ability to reach The Crows. Shoot every crow in the area to make Chromatic Chapelier appear. In battle, do not rely on light- or dark-based damage: the boss is described as completely resistant to both. Its revolving masks can silence characters if they hit, so account for the possibility of losing access to their abilities. The source identifies these mechanics but does not provide a full move-by-move strategy.
Clea: clear the Flying Manor trials, then focus on parries
In Act 3, fly to the Flying Manor with Esquie. Complete all four trials and then go through the door ahead of them to reach Clea. The central fight advice is to take parry and counter opportunities seriously: missed opportunities heal her and extend the encounter. The available guide does not establish a detailed sequence or alternative counter strategy.

Simon: prepare your characters before descending into the Abyss
While exploring Renoir’s Drafts, enter the opening at the glowing pillar. Head toward the cliff and drop down to reach Simon. The guide calls this one of the game’s most challenging secret fights and advises building each character first, but it does not specify a level threshold, party setup, or proven build. Treat that as a broad preparation warning, not a precise requirement.
Alicia: start Maelle’s Level 7 relationship quest
Begin Maelle’s Level 7 relationship quest to trigger the fight at the top of The Reacher. This encounter is a solo battle between Alicia and Maelle, not a standard full-party boss fight. The available guide information does not give a more specific tactic, so make sure you understand that the encounter is centered on Maelle before starting it.

Chromatic Clair Obscur: return to the Monolith after the Paintress
Defeat the Paintress, then return to the Monolith and climb to the top again to find Chromatic Clair Obscur. The source establishes this post-boss return as the unlock condition but does not describe the boss’s attacks or a particular way to counter them; no specific build or tactic can be recommended from that information.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How this five-boss list fits the wider game
“Secret bosses” refers here to the five encounters named in the dedicated hidden-boss guide, not to every optional fight. Broader indexes separate optional overworld bosses, Chromatic variants, and later Endless Tower encounters. Game8’s overview also lists Patch 1.5.0 areas and additional boss guides, so players seeking every optional challenge should consult the broader boss and game guide index rather than treating this five-entry list as exhaustive.
