Slay the Spire 2 Patch Buffs Aeonglass Boss, Reworks Cards and Enemies

Mega Crit has rolled out a new patch for Slay the Spire 2 that buffs Aeonglass, the latest boss in the game. This update also includes various enemy and card reworks, some of which the official patch notes didn’t mention. The community has taken notice of these undocumented changes, especially after a previous update sparked a review bombing campaign against the game.

The buff for Aeonglass indicates that Mega Crit is making adjustments to increase the boss’s difficulty. This suggests that player data revealed the encounter was too easy. The unlisted changes matter because they introduce balance elements players can’t anticipate without testing them firsthand. This lack of transparency adds to the existing tensions from recent community feedback.

That context is important. As GamesRadar reported, this patch follows an earlier update that caused a wave of coordinated review bombing. Mega Crit has made adjustments since then, and the game’s overall Steam rating remains at 93% positive across 57,897 reviews. This resilient figure suggests that the core playerbase is still engaged, despite the recent issues.

Slay the Spire 2 entered Early Access on March 6, 2026, priced at $24.99, and currently boasts 156,385 concurrent players on Steam. For a $25 Early Access card roguelike, those numbers are impressive, giving Mega Crit plenty of room to refine the game. The original Slay the Spire spent about two years in Early Access before its full release, so it’s not unusual for this studio to release frequent, sometimes imperfect updates.

The trend of unlisted changes deserves attention. When balance tweaks don’t show up in patch notes, players trying to create builds around certain cards or enemy interactions are left with incomplete information. In a game where deck-building relies on exact numbers, this gap between what’s coded and what’s documented can quickly undermine trust more than any single balance decision could.

So far, community reaction to this patch has leaned negative. One Steam reviewer commented that the game is “totally RNG based,” which is a common criticism that pops up during balance patches when players feel like their control over the game is diminishing. This complaint has been around for a while, but patch cycles often amplify existing frustrations. GameSpot discussed Mega Crit’s adjustments after the review bombing, highlighting how the developer has been willing to reverse changes when the community pushes back. This might explain why they’re being cautious with this follow-up patch.

What To Watch

• Patch note completeness: Keep an eye on whether Mega Crit provides a follow-up that clarifies all the undocumented changes in this patch. Community trust will depend on that transparency.
• Aeonglass difficulty data: Look for player feedback on whether the boss buff hit the mark, or if it overcorrects and leads to more negative reactions.
• Steam review trajectory: The 93% positive rating held up well after the last review bomb; monitor whether ongoing patch controversies affect this figure as Early Access continues.
