This is a pre-release internal note from the closed playtest, quoted as it was written for testers. It describes a build that no longer exists; treat it as history, not as a description of the current game.
Happy New Year! This patch brings the start of fixes for hitching peroformance issues, a wave of card reworks across multiple characters, changes to the Necrobinder starter deck, Zlatir reworked into Vakuu, and a new score-based Epoch unlock system.
