Clair Obscur Expedition 33

A new patch is available for Sandfall Interactive’s Clair Obscur: Expedition 33, offering some adjustments to Story Mode balance and even offering a rematch against the most challenging optional boss. Spoilers follow, so be warned.

Ver 1.3.0 increases the parry and dodge windows by 40 percent in Story Mode, making it much easier to survive attacks. If you do get hit, incoming damage has been reduced by 10 percent and is now at 50 percent. Whether this will let you tackle the toughest optional bosses or not, especially if you fail every single parry and dodge, remains to be seen.

As for the most challenging boss in the game, Simon, you can now rematch against him. However, from Act 3 onwards, players can also activate challenge modifiers to limit their damage to 99,999 or 999,999. Enemy HP can also be multiplied from x2 to x100 if you really want to push the limits of some fights.

Check out the full patch notes below, including examples of the 297 bug fixes. Sandfall Interactive is investigating issues with mouse sensitivity after this patch, so stay tuned for further updates.
