The update removes the controversial Act 3 boss Door Maker, replacing it with a new boss called Eternal Hourglass. The development team said Door Maker forced interesting decisions but exceeded their complexity threshold and had unresolved issues. Steam Workshop support is now live, allowing players to browse and install mods directly in the game. A monster encyclopedia feature has also been added, letting players view encountered monsters and their animations, with plans to expand it to include stats and lore. The update overhauls the random number generator after mathematician Andy Tockman published a report on June 15 showing significant bias in random events. For example, the Curse card from Neow's Bone relic had a 73.74% chance of being Anguish on one path and a 0% chance of Debt on another. The RNG fix was implemented unusually fast, skipping the usual beta testing cycle. The patch also includes new relics, badges, character balance adjustments, and UI improvements.","whyItMatters":"The swift RNG overhaul, prompted by an external mathematician's analysis, shows Mega Crit treating early access as a genuine feedback loop rather than a marketing phase, and the Door Maker removal signals a willingness to cut content that does not meet design goals even late in development.","webCardHtml":"\u003cp\u003eMega Crit released the second major update for \u003cem\u003eSlay the Spire 2\u003c/em\u003e on June 19, 2026, consolidating four previous beta patches into one. The update is version 0.107.1 for the main branch.\u003c/p\u003e\n\u003cp\u003eThe new Act 3 boss Eternal Hourglass has an ability that adds an unplayable \u0026#34;Decay\u0026#34; card to the player\u0026#39;s hand every time they play a certain number of non-status cards. The boss underwent multiple balance adjustments during the beta period before appearing in this patch. Other enemies like Parasitic Prism and Swarming Mass were also reworked.\u003c/p\u003e\n\u003cp\u003eThe random number generator overhaul came after mathematician Andy Tockman, who holds a bachelor\u0026#39;s in mathematics and computer science from MIT and a master\u0026#39;s in computer science, published a technical report on June 15 titled \u0026#34;Correlated randomness in Slay the Spire 2.\u0026#34; Tockman identified that the game uses \u0026#34;Correlated RNG,\u0026#34; where the output of one random number generator provides information about another. For example, on the Underground Waterways path, the Defect\u0026#39;s Lightning Orb has a 75% chance of hitting the left enemy in the first battle. By observing past random results, players could predict orb attack direction with over 95% accuracy against Slimers. Tockman also found that the card \u0026#34;Rebound\u0026#34; had a 0% chance of appearing from the Junk Heap event, making it unobtainable outside multiplayer. Mega Crit thanked Tockman in the patch notes, saying \u0026#34;your suffering is now truly random!\u0026#34;\u003c/p\u003e\n\u003cp\u003eOther additions include three new badges based on multiplayer contributions, UI improvements like detailed error notifications and better controller support, and multilingual translation fixes including Japanese. The game is available in early access on Windows, Mac, and Linux via Steam.\u003c/p\u003e","blueskyPost":"Mega Crit skipped beta testing for the RNG fix after a mathematician's report showed a 73.74% chance for one Curse type on a specific path. The speed of the patch suggests the bias was severe enough to warrant an emergency bypass.","twitterPost":"Mega Crit skipped beta testing for the RNG fix after a mathematician found a 73.74% bias in one Curse outcome. That speed signals the bug was critical.","threadsPost":"Mega Crit pushed the RNG fix from the mathematician's report directly to the main branch, skipping beta entirely. The bias was stark: one Curse type had a 73.74% chance on a specific path. That speed of response tells you the bug was borderline game-breaking, not a minor imbalance.","newsletterBlurb":"Slay the Spire 2's second major update removes the unpopular Door Maker boss, adds Eternal Hourglass, and enables Steam Workshop mod support. The update also overhauls the random number generator after a mathematician proved the game's RNG was biased, making some cards unobtainable and outcomes predictable.","attributionJson":"[{\"source\":\"4Gamer.net\",\"url\":\"https://www.4gamer.net/games/790/G079033/20260619025/\",\"title\":\"Slay the Spire 2 Third-Floor Boss Door Maker Finally Removed from Main Branch as Well; Second Major Update Implemented\"},{\"source\":\"Automaton\",\"url\":\"https://automaton-media.com/articles/newsjp/20260619-450597/\",\"title\":\"Slay the Spire 2 Major Update Released: Door Maker Removed, New Boss Officially Added, RNG Bias Fixed, and More Changes\"},{\"source\":\"Automaton\",\"url\":\"https://automaton-media.com/articles/newsjp/20260619-450723/\",\"title\":\"Mathematician Analyzes Random Number Bias Bug in Slay the Spire 2, Leading to Fix; Some Cards Were Unobtainable, Bad Luck Wasn't Just in Your Head\"},{\"source\":\"Game Spark\",\"url\":\"http://www.gamespark.jp/article/2026/06/19/168190.html\",\"title\":\"Slay the Spire 2 Unpopular Boss Door Maker Officially Removed and Workshop Support Added in Second Major Update.
