v0.107.1 · Major Update #2
main · 2026-06-18The current public main-branch baseline used by this site. It replaces Doormaker with Aeonglass and adds major reference and modding features.
What the current balance changes actually mean
v0.107.1 main · v0.110.0 beta trackedA plain-language guide to Aeonglass, Defect, high Ascension, and co-op concerns without mixing main-branch and Beta values.
The Guardian
Act 1 · Medium danger · HP 240Never use multi-hit attacks in Defensive Mode — Thorns will shred your HP fast.
Ironclad
Strength, Exhaust, and block scalingIronclad wins by turning HP and cards into permanent combat advantage: Strength makes attacks matter, Exhaust trims the deck, and Barricade-style block engines buy enough time for boss fights.
Ironclad Strength Burst
Ironclad · Strength BurstStack Strength, then convert it into one or two turns of overwhelming attack damage.
Inflame
Ironclad · S-tier · Power · UncommonPermanent Strength buff that improves every attack for the rest of the fight — the cheapest scaling Ironclad has.
Boss Prep Checklist
Run toolPrepare for bosses with warnings, checklist items, and card recommendations.
v0.110.0 · Beta Patch
beta · 2026-07-31A preview branch, not the default public-game baseline. It adds another balance pass, reverts Mirage and Pillar of Creation toward their earlier roles, adds keyboard-only mode, and fixes multiplayer, Bestiary, localization, and modded-session reporting issues.
Co-op planning, roles, and troubleshooting
v0.107.1 main · v0.110.0 beta notesCoordinate party jobs, rewards, and version checks so a multiplayer run does not become several isolated solo decks.
Hexaghost
Act 1 · High danger · HP 250Do NOT drink HP potions before the fight — higher HP = harder first hit!
Silent
Poison, shivs, discard, and defenseSilent is strongest when the deck commits early: Poison solves long fights, shivs and Accuracy solve burst turns, and discard/draw keeps the best cards cycling.
Ironclad Block Exhaust Engine
Ironclad · Block ExhaustUse Exhaust to shrink the deck, draw more cards, and turn defense into damage.
Demon Form
Ironclad · A-tier · Power · RareCompounding Strength every turn snowballs out of control in long fights, though the 3-cost turn it lands is a tempo hit.
Run Tools
Tools hubOpen the card pick assistant and boss prep checklist from one place.
v0.109.1 · Beta Hotfix
hotfix · 2026-07-25A narrow hotfix for the v0.109.0 beta branch. It syncs corrected Traditional Chinese translations to fix broken plural evaluation and does not change combat balance.
Build stability: test the floor, not only the ceiling
v0.107.1Judge a build by first-cycle output, bad-draw recovery, boss coverage, and patch sensitivity—not by its best screenshot.
Slime Boss
Act 1 · Low danger · HP 140Don't let Slimed cards pile up in your deck — they severely dilute your hand quality.
Defect
Orb scaling, Focus, and energy burstsDefect turns a small Focus lead into a whole fight plan. Good decks either scale orb output every turn or compress the fight with energy and zero-cost tempo.
Silent Poison Control
Silent · Poison ControlUse Poison as the win condition while Weak, Block, and draw carry the setup turns.
Offering
Ironclad · S-tier · Skill · RareTwo energy and three cards for free is the strongest single-turn burst enabler in the game — HP is a resource here.
Workshop, saves, and version-mismatch FAQ
v0.107.1 main · v0.110.0 beta notesSeparate save behavior from post-patch mod failures, then diagnose dependencies, platform support, and multiplayer hashes in a controlled order.
Waterfall Giant
Act 1 · High danger · HP 240 / 250 (A8+)Do not kill Waterfall Giant just because you can. Check the next-turn explosion first or the deathrattle can end the run.
Necrobinder
Osty, sacrifice, graveyard, and countdown pressureNecrobinder rewards planning around delayed payoffs. Sacrifice and graveyard tools can snowball, but the deck must keep enough immediate defense to survive setup turns.
Silent Shiv Burst
Silent · Shiv BurstCreate many small attacks, multiply them with Accuracy-style scaling, then finish with burst payoffs.
Impervious
Ironclad · A-tier · Skill · RareThirty Block in one card is a lifesaver against boss burst turns; Exhaust keeps it out of your deck the rest of the fight.
Route planning: choose the next requirement, not the richest path
v0.107.1A practical map heuristic for elites, upgrades, shops, recovery, and Act 3 boss insurance.
The Insatiable
Act 2 · Extreme danger · HP 321 / 341 (A8+)Sandpit is an instant-kill timer. If your deck is bloated or cannot draw Frantic Escape on time, normal block will not save you.
Regent
Stars, weapon creation, Forge, and card generationRegent is a scaling planner: stars and created weapons create inevitability, while Forge and Prophesize let the deck line up a decisive future turn.
Defect Focus Orbs
Defect · Focus OrbsScale Focus and orb slots so Lightning, Frost, and Dark orbs solve the fight passively.
Dark Embrace
Ironclad · A-tier · Power · RareTurns Ironclad’s Exhaust theme into a draw engine — with enough exhausters it refills your hand every turn.
The Collector
Act 2 · High danger · HP 300Killing Torch Head buffs The Collector — think carefully before clearing minions.
Defect Zero-Cost Tempo
Defect · Zero-Cost TempoChain cheap cards, energy spikes, and recursion to win before the enemy plan stabilizes.
Feed
Ironclad · A-tier · Attack · RarePermanent Max HP growth off kills is how Ironclad survives the long climb — snowballs hard against fodder enemies.
Champ
Act 2 · High danger · HP 440His Block resets every turn — low-output builds can't break through. Stack Poison or save a burst turn.
Necrobinder Osty Sacrifice
Necrobinder · Osty SacrificeTrade temporary resources for graveyard and sacrifice payoffs that snowball over the fight.
Whirlwind
Ironclad · A-tier · Attack · UncommonDumps all energy into multi-target damage — indispensable for multi-enemy rooms.
Bronze Automaton
Act 2 · Medium danger · HP 300Kill Bronze Orbs first — ignoring them lets their sustained damage overwhelm you.
Necrobinder Countdown Control
Necrobinder · Countdown ControlDelay enemy plans while countdown and graveyard effects line up a lethal future turn.
Corruption
Ironclad · A-tier · Power · AncientFree Skills turn every defensive card into tempo and fuel Dark Embrace draw — the centerpiece of the Exhaust archetype.
