Mega Crit is actively balancing Slay the Spire 2 through beta patches, with the latest v0.111.0 released on August 14, 2026, reworking Ironclad's Battle Trance and buffing enemies. The game remains in early access with Steam Workshop support live.
Mega Crit has been iterating on Slay the Spire 2 through a series of beta patches and major updates since June 2026. The second major update, released June 19, removed the Act 3 boss Door Maker and replaced it with Eternal Hourglass, citing that Door Maker exceeded the team's complexity threshold and had unresolved issues. The same update brought Steam Workshop support to the main branch, added a monster encyclopedia, and overhauled the random number generator after mathematician Andy Tockman published a report on June 15 showing significant bias in random events, such as a 73.74% chance of drawing the Anguish Curse from Neow's Bone relic on one path.
Subsequent beta patches have focused on rebalancing characters. The July 3 update v0.108.0 nerfed Defect's Compression and Ironclad's Crimson Garment, reworked Silent's Infectious Explosion, and buffed Necrobinder's Soul Storm. The August 14 update v0.111.0 reworked Ironclad's Battle Trance from an energy-generating card into a block-generating one, now costing 3 energy and granting 15 Block plus 5 additional Block per point of Strength. This removed one of Ironclad's rare energy sources. The same patch simplified Forgotten Ritual, nerfed Silent's Ink Blade, buffed Necrobinder's Doom, and reworked Defect's Hyper Beam, while buffing several enemies including Axe Machine, Mechanite, Exoskeleton Bug, Globe Head, Ancestor Bug, and Soul Fish.
These changes indicate a balancing approach that targets dominant strategies and raises the overall difficulty ceiling. The RNG fix was implemented unusually fast, skipping the usual beta testing cycle, suggesting a responsive development process during early access.

Aug 14
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.
Jul 3
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.
Jun 19
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.
