Slay the Spire 2 is in early access, with over 3 million copies sold, and is receiving regular beta patches and major updates that rebalance characters, replace bosses, and fix RNG bias.
Slay the Spire 2 launched into early access in March 2026 and has sold over 3 million copies. The first official physical merchandise, Regent and Necrobinder vinyl figures from Youtooz, went up for pre-order in July, with shipments scheduled from January to March 2027. The figures stand 13 cm tall and cost $29.99 each.
Mega Crit has been actively updating the game through its early access period. The second major update, released on June 19, 2026, removed the controversial Act 3 boss Door Maker and replaced it with a new boss called Eternal Hourglass. The same update overhauled the random number generator after mathematician Andy Tockman published a report on June 15 showing significant bias in random events. The RNG fix was implemented unusually fast, skipping the usual beta testing cycle. The update also added Steam Workshop support and a monster encyclopedia feature.
Beta patches have continued to refine the game. Patch v0.107.0, released in early June, adjusted the Eternal Hourglass boss by removing its Decay debuff and altering block gain timing, while strengthening the early-game Squirming Swarm enemy at higher ascensions. Patch v0.108.0, released on July 3, nerfed Defect's Compression and Ironclad's Crimson Garment, reworked Silent's Infectious Explosion, and buffed Necrobinder's Soul Storm. The Act 3 boss Eternal Hourglass also received new animations in that patch.

Automaton recommends 'Chaos Zero Nightmare,' a deck-building roguelike from SUPER CREATIVE and Smilegate, for players who have exhausted 'Slay the Spire 2' early access. The game's 'Chaos Manifestation' mode lets players build decks and save them for normal mode, offering a different take on the genre.
Mega Crit released beta patch v0.111.0 for Slay the Spire 2 on August 14, 2026. The update reworks Ironclad's popular skill Battle Trance, turning it from an energy-generating card into a block-generating one. Battle Trance now costs 3 energy and grants 15 Block, plus 5 additional Block for each point of Strength the character has. Previously, it granted 1 energy for each Attack card in hand and prevented gaining additional energy that turn. The change removes one of Ironclad's rare energy sources. Another Ironclad skill, Forgotten Ritual, was simplified to grant 3 energy and Exhaust, making it easier to pick up without requiring exhaust synergy. Silent's Ink Blade was nerfed: the Ink enchantment on knives lost its additional 1 damage effect, while applying 1 Weak remains. Necrobinder's Doom was buffed by removing Exhaust, allowing repeated use against enemies with Ruin stacks. Defect's Hyper Beam was reworked: losing 3 Focus now applies only for the turn, but its area damage dropped from 30 to 24. Several enemies, including Axe Machine, Mechanite, Exoskeleton Bug, Globe Head, Ancestor Bug, and Soul Fish, received stat buffs, making the climb harder. The patch also adds idle animations for characters at low HP, Indonesian language support, and an E key confirm feature.
Mega Crit released beta patch v0.110.0 for Slay the Spire 2 on July 31, 2026. The update adds a keyboard-only mode that displays hotkey settings on screen, helping players without a mouse. Player characters also gain special auras when playing certain buff cards, alongside card tuning, bug fixes, and UI changes.
Mega Crit and figure manufacturer Youtooz have opened pre-orders for the first official figures based on the deck-building roguelike sequel Slay the Spire 2. The line includes two playable characters: Regent, depicted seated on a stone throne supported by two minions, and Necrobinder, standing with a scythe and accompanied by the skeletal hand Osty. Each vinyl figure stands approximately 12.7 cm (5 inches) tall and is priced at $29.99. Buyers can also choose a bundle that includes a 2-inch pin badge. The packaging features artwork that reflects the game's atmosphere. Shipments are scheduled between January 30 and March 15, 2027. Slay the Spire 2 entered early access on Steam on March 6, 2026, and has sold over 3 million copies as of March 2026.
Mega Crit released update v0.108.0 for the Slay the Spire 2 beta branch on July 3. The patch nerfs Defect's Compression and Ironclad's Crimson Garment, reworks Silent's Infectious Explosion, and buffs Necrobinder's Soul Storm. The Act 3 boss Eternal Hourglass also received animations.
Mega Crit released the second major update for Slay the Spire 2 on June 19, 2026, bringing the beta branch changes to the main branch. 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.
