What changed on the main branch

Major Update #2 rolled several beta patches into the default build. Aeonglass replaced The Doormaker as an Act 3 boss, the Bestiary became available in the Compendium, and Steam Workshop support was added.

Mega Crit also replaced the game's pseudorandom number generator after a correlated-RNG problem was documented. The update includes a larger set of balance, enemy, art, performance, multiplayer, and bug-fix changes, so the official notes remain the source of truth for individual numbers.

What is in beta v0.110.0

The optional beta adds a keyboard-only control mode, a map Share button, new card art and character-form effects, and another group of card and relic balance changes. It also fixes interface, multiplayer, enemy, event, and modding issues.

Beta values are experimental. A card or relic shown in beta notes may still differ from the default main branch, and later beta changes can revert an earlier rework before it reaches everyone.

How to check which version you are using

  • If you never opted into a Steam beta, compare your in-game version with v0.107.1.
  • If you selected the public beta under Steam Properties, compare against v0.110.0.
  • When a guide disagrees with the game, check its branch and date before assuming either set of numbers is current.
