Clair Obscur: Expedition 33 has just released Patch v1.3.0, and while the update notes may be brief, it includes one major addition that fans of a serious challenge will appreciate: the ability to rematch the game’s toughest boss.
Yes, the infamous Simon fight, known for its brutal difficulty and relentless demand for precise parries, can now be replayed as many times as you like. If you’ve already conquered him once and feel the urge to test your skills (or your patience) all over again, you now have the chance.
Story mode is now actually easy, and for those who want even more of a challenge, there's something for you

Simon isn't the only change in Patch 1.3.0, Sandfall Interactive has also made significant adjustments to both ends of the difficulty spectrum.
For players who want an even tougher experience, new challenge modifiers have been introduced for Act 3 and beyond, that can be adjusted at the flag.
On the other end of the scale, Story Mode has finally been rebalanced to truly offer an easier path through the game.
Story mode, while the easiest difficulty claims that you don't need to master the art of parrying and dodging, anyone who's got into Act 3 will know this is nonsense. Even in Story mode, some bosses require parries and dodges to defeat.
While certain late-game builds using specific Pictos could help mitigate the difficulty, many of these tools weren’t accessible until much later. With this update, Story Mode now better lives up to its promise, making the game more approachable for those who want to focus on the story without the punishing combat.
