Frosthaven Patch 0.12.1.29652 Delivers Network Backend and Rule Fixes

Frosthaven patch 0.12.1.29652 implements a new network backend and adds range and damage displays for retaliate to the UI. The patch also resolves numerous multiplayer desyncs, card interaction errors, and quest progression blocks.

Frosthaven receives a comprehensive maintenance and feature patch with version 0.12.1.29652, deploying the new network backend previously tested in public test branches. Alongside network improvements, the update addresses dozens of specific card interactions, quest logic errors, and UI displays.

UI and Network Backend

Players can now test the new network backend live. The user interface has also been updated to show range and damage values for retaliate abilities, helping players calculate incoming damage more accurately.

Multiplayer and Card Interaction Fixes

The patch resolves multiplayer issues tied to Undo actions and desyncs. Card-specific errors have been stamped out, including issues with the Meteor card 'Eruption', Astral's once-per-battle infusion triggers, and Shackles using Mirrored Knife while affected by 'Delayed Malady'. Furthermore, advantage now correctly nullifies disadvantage during outpost attacks.

Quest Progression and Logic Corrections

Several quest-breaking bugs have been fixed. In quest 84 'Here There Be Oozes', the Elder Ooze and Prism now interact correctly with slime mechanics. Quest 28 'Summit Meeting' no longer breaks under the 'Toxic Termination' challenge, and escape hexes now unlock properly once requirements are met. Other fixes prevent summons from spawning incorrectly in quest 31 'Cracking Tunnel' and stop characters from getting stuck during deep terror card banishments in quest 27.

Why this patch matters

Patch 0.12.1.29652 provides crucial stability for multiplayer campaigns while clearing out a massive backlog of niche card and quest logic bugs.
