Beta v0.110.0: Mirage & Pillar of Creation Reverts, Keyboard-Only Mode & Form VFX
The July 31 beta patch mixes balance changes with partial reverts of the v0.109.0 redesigns. Mirage and Pillar of Creation return to their pre-0.109.0 versions with small tweaks — Mirage gains Block from enemy Poison again and no longer Exhausts, while Pillar of Creation triggers on every created card again at reduced Block. The patch also adds a keyboard-only control option, a map Share button, new polished portrait art for many cards, form VFX for characters, and a wide set of Ancient, character and multiplayer adjustments plus bug fixes.
- •Mirage reverted to its pre-0.109.0 version (Block based on enemy Poison) and no longer Exhausts.
- •Pillar of Creation triggers on every created card again, with Block reduced 3(4) -> 2(3); Regalite reworked to the once-per-turn version with 6 Block.
- •New keyboard-only control option plus a Share button that screenshots the entire map.
Beta Hotfix v0.109.1: Traditional Chinese Plural Fix
A tiny beta hotfix with one important fix for players using Traditional Chinese: corrected Traditional Chinese translations were synced to fix broken plural evaluation introduced alongside the new zht language support in v0.109.0.
- •Synced corrected Traditional Chinese translations to fix broken plural evaluation
- •No gameplay or balance changes — this hotfix only affects Traditional Chinese text
Beta v0.109.0: New Neow Relics, Diamond Diadem Rework & Silent Redesigns
The July 17 beta patch is a major balance and content update. Two new Neow relics headline the patch: Dowsing Rod adds the Dowsing quest card that transforms into Abundance, and Neow’s Sacrifice grants the exclusive Ambergris potion at the cost of a Guilty curse. Diamond Diadem is reworked into an opening-Block relic, Bloodletting moves up to Uncommon, Silent’s Well-Laid Plans, Mirage and Expertise are all redesigned, several multiplayer cards are nerfed, Aeonglass and Torchhead Amalgam trade front-loaded damage, and the game gains early Traditional Chinese support alongside a long list of bug fixes.
- •Two new Neow relics: Dowsing Rod (adds the Dowsing quest card, which transforms into Abundance) and Neow’s Sacrifice (grants the exclusive Ambergris potion plus a Guilty curse).
- •Diamond Diadem reworked: now starts combat with 20 Block that is not removed at the start of your next turn.
- •Silent gets three redesigns: Well-Laid Plans (Rare, stop discarding your hand), Mirage (0-cost next-turn Energy) and Expertise (draw 2(3) with Retain).
Beta v0.108.0: Modded Save Copy, Custom Run Randomizer & Multiplayer Cards
The July 2026 beta patch focuses on modding reliability, Custom Run variety, Bestiary improvements, multiplayer card content, UI polish, balance changes and bug fixes. Highlights include automatic copying from unmodded saves into the modded save directory on first modded launch, a Custom Run Randomize button, pause-menu timer pausing in single player, a Bestiary stats section, Aeonglass animations, and a large batch of new multiplayer cards.
- •Modded first launch now copies unmodded saves into the modded save directory and explains the separation in a popup.
- •Custom Run gains a Randomize button that chooses two good modifiers, one bad modifier and a random character.
- •Single-player run timer now pauses while the Pause Menu is open.
Major Update #2: Beta Rollup, RNG Rework & Steam Workshop
The second major main-branch update rolls four beta patches into live. Aeonglass, the Bestiary, the v0.105-v0.107 enemy and card balance era, Steam Workshop support, and a major RNG rework are now on the main branch. This is also a large stability pass with save-file resilience, controller, Linux, multiplayer, translation, UI, art, audio and performance fixes.
- •Main branch now includes the recent beta rollup: Aeonglass, Bestiary and the v0.105-v0.107 balance changes
- •RNG rework fixes correlated random outcomes between unrelated run systems
- •Steam Workshop support is live, giving mods an official subscription and update path
Beta Patch: Beta → Main Groundwork — Stability, Bug Fixes & Minor Balance
A deliberately smaller bi-weekly patch whose main purpose is to lay the groundwork for merging the beta branch into main. It is stability-first: a large bug-fix pass plus UI/UX/QoL and performance work, with only a few balance changes and art additions. Aeonglass is simplified (no longer applies Ebb), Skulking Colony is buffed further, and several cards across Ironclad, Regent and Necrobinder get tuned. Includes a new Defect power-up animation.
- •Groundwork laid for moving the beta branch onto main — this patch is stability-first

Dozens of crash fixes (dying creatures, controller card pile, Linux combat and ICU), extensive controller/Steam Deck navigation fixes, and a long list of relic, event and multiplayer fixes. Note: the new Aeonglass boss and the Bestiary remain beta-only and are not part of this main update.
