The primary focus of this patch is player control in the roguelike. In particular, the subjective feeling that you have enough control to steer your build into something fun and powerful from run to run.
The main update for that is a new system allowing you to spend your money to reroll card rewards, or, perhaps more interestingly, claim all 3.
It's a big patch, so read the full notes here: https://www.flaregatenetwork.com/patch-notes/july-31-2026
