Clair Obscur optional bosses: what order to do them in and how to reach Simon
Sprong, the Chromatic Pétank, the Serpenphare, Clea, the Painting Workshop, the 33 Endless Tower fights and Simon: the order that makes each one easier than the last, the trick to each fight and how to get Professional without risk.
SprongBronze33.40%And it counts towards Carreau Parfait, À On, Clea, Noir et Blanc, “Endless”, Peace At Last, Professional, required for the platinum.
The order that works
The eight optional boss and challenge trophies average 25.7%, and almost all of them open in Act III, when Esquie flies. The order matters because each boss leaves you something for the next: Sprong gives the Pictos that grants two turns in a row, the Serpenphare a catalyst to take a weapon to level 33, and the Endless Tower levels you up along the way. Simon, always last.
| Order | Trophy | The trick |
|---|---|---|
| 1 | Carreau Parfait (22.2%) | Chase it with Esquie to its platform; stun the Pétanks it summons |
| 2 | Sprong (33.4%) | Its fourth stage is a free turn; it gives the two-turn Pictos |
| 3 | Endless (20.1%), early stages | Rest between fights; no need to do it in one go |
| 4 | À On (26.4%) | Spend your AP before it absorbs it; dodge its explosion |
| 5 | Clea (21.6%) | Four bosses before the door; she heals when she hits you |
| 6 | Noir et Blanc (20.4%) | Three entrances, three items to the statue, then the boss |
| 7 | Endless, final stages | 33 fights in total; the 1.5.0 bosses do not count |
| 8 | Peace At Last (15.5%) | With level 99 and everything else done |
Simon: what he does and how not to lose the party
Simon waits at the end of an optional endgame zone and is the toughest fight in the game. He has two phases. In the first, four combos you have to learn to parry or dodge; if he kills a character who is not revived instantly, he can erase them from the fight, so bring effects that prevent death or revive automatically. He also steals your shields and, when he gathers Chroma around a character, drops their health to 1.
In the second phase every sword combo carries a delayed extra hit: be ready to defend twice. And before he falls, he wipes your main party in one go and forces the reserve in. There are two ways to handle it: finish him before he does it, with the level 3 Gradient Attack saved up, or keep your strongest characters in reserve to finish with them.
Arrive at level 99 with the endgame Pictos; every failed attempt still gives experience.
Peace At Last’s 15.5% sits above the journals (11.1%) and the records (11.5%). Simon is the hardest fight, but not the rarest trophy.
Professional without risk
Professional (46.1%) asks you to beat a boss without taking damage. Chromatic bosses count, Mimes do not. The safe play is not to fight the optional chromatic boss in Spring Meadows at the time, when it is above your level, and come back with the endgame party: it falls before it can act twice.
