Ceremonial Beast is an early burst-timing check. The fight is at its easiest before the stun threshold and becomes dramatically worse once Ringing restricts your card plays.
Expect a non-damaging setup turn first, then heavy hits that scale with Strength.
At roughly 150 HP, the boss becomes Stunned and drops its accumulated Strength. That is your cleanest burst window.
After the stun, Ringing limits you to 1 card per turn, so lingering too long in phase 2 is how stable decks lose.
Weak, Disarm, and frontloaded damage are the best answers. Multi-hit attacks also convert the stun window into more damage than single big swings.
Kin Priest is the clearest early AoE test. The main body is not the real problem; the adds are, because they create the pressure that makes the fight spiral.
The fight gets harder if the side units survive long enough to keep feeding heals, buffs, or debuffs into the board state.
AoE is ideal, but cheap single-target attacks still work if you kill one add quickly and reduce the incoming pressure.
Artifact and debuff prevention matter more here than they do in most other Act 1 fights.
If you cannot clear the side units, treat this as a tempo race, not a scaling fight.
Lagavulin Matriarch is the classic setup check. The sleep phase is not flavor text; it is the reason the fight can be favorable if your deck actually has engines worth deploying.
Use the sleep turns to deploy Powers, setup relic interactions, or expensive engine cards you would hate drawing under pressure.
If your deck has no meaningful setup, waking the boss earlier can be better than wasting dead turns.
The awakened phase hits much harder than STS1 players expect, so this is not a free nostalgia fight.
Poison and persistent scaling perform well because the boss gives you time to establish them.
Soul Fysh is one of the nastiest deck-management fights in the game. Beckon cards create unblockable pressure if you cannot play or discard them cleanly, and Intangible compresses your damage windows.
The dangerous loop is simple: Beckon taxes your energy, then Vulnerable and Intangible make each mistake more expensive.
Turns before Intangible are your damage window. Turns during Intangible are for blocking, discarding status, and preparing the next burst cycle.
Acrobatics, Burning Pact, Calculated Gamble, and other cheap discard/exhaust tools are unusually strong here because they neutralize Beckon overhead.
If your deck cannot manage statuses efficiently, this fight feels much worse than its raw HP suggests.
Knowledge Demon is a hard DPS check disguised as a pattern fight. Every full cycle permanently improves the boss while also weakening your deck through the forced debuff choice.
The three-hit strike is the turn that punishes weak block packages the hardest.
The runes turn matters almost as much because the boss heals and gains permanent Strength at the same time.
Disintegration is usually the least harmful debuff choice; Sloth and Sap are the ones most decks should avoid if possible.
If you are trying to outlast this boss with passive defense, you are usually already losing. Kill speed is the real answer.
The Insatiable is the cleanest clock boss in the current game. Sandpit means the fight has a literal expiry timer, so all the usual "play safe and stabilize" instincts become traps.
Frantic Escape exists to buy time, not to solve the fight. You still need enough damage to end the encounter before the timer and scaling both overwhelm you.
Only play the timer reset cards when you truly need them. Spending too much energy on safety loses the same way greed does.
Slow Poison and Doom setups perform much worse here than their general strength would suggest.
Burst, energy generation, and immediate damage matter more than premium block.
Kaiser Crab went from placeholder data in the old guide to a real matchup you can plan for. Community consensus still varies on exact numbers, but the important strategic pattern is clear: Block walls plus escalating claw pressure.
The fight alternates between denying your normal damage line and threatening you with heavy multi-hit pressure.
Poison is one of the best answers because it bypasses the Block problem entirely.
Strength and Doom also scale into the fight better than medium-value fair damage.
If your deck needs long setup and cannot punish the open windows, Kaiser Crab becomes one of the roughest Act 2 bosses.
Doormaker is not the fastest killer, but it is one of the longest endurance fights. The portals extend the encounter, so the total work your deck has to do is much higher than the boss HP line suggests.
The boss periodically vanishes and forces you to clear Disappearing Doors before returning.
Because the fight drags, sustainable scaling and reliable block beat one-shot burst plans.
Poison, Doom, Strength stacking, and Barricade-style defense all gain value here.
Treat the fight as attrition. If your deck only has one big spike, it often runs out of real work after the first cycle.
Test Subject is still the hardest boss in the current build because every phase asks for a different answer and phase transitions wipe away the debuffs that many top decks rely on.
Phase 1 rewards attack-heavy turns because Skill-heavy turns feed the boss too much value.
Phase 2 punishes unblocked hits by dirtying your deck with Wounds, so defense becomes part of your damage plan.
Phase 3 creates burst windows around Intangible turns, which means timing matters as much as output.
Poison and Doom are much worse here than against The Queen because all that setup gets reset between phases.
Raw Strength, consistent block, and decks that can rebuild pressure repeatedly are the most reliable answers.
The Queen is the new Act 3 boss added in the richer PR data. She is dangerous for a different reason than Test Subject: instead of resetting your progress, she constrains your hand through Bind and asks whether your deck can still function when your natural sequencing is disrupted.
Phase 1 revolves around the Summon, which you want dead before it scales too far out of range.
Phase 2 is the real Queen fight and the Bind mechanic is the signature problem: 3 cards in hand are locked together and only 1 of them can be played.
Mid-turn draw partially cheats this restriction, so draw-heavy decks gain real value here.
Unlike Test Subject, debuffs persist across phases. That makes Poison and Doom much better against The Queen than many players first assume.
Single huge attacks or repeatable high-value attacks also perform well because the fight punishes quantity of card plays more than quality of each play.
Boss strength is not universal. A deck that farms Vantom can fold to The Insatiable, and a build that destroys The Queen can look terrible into Test Subject. The point of this section is to make that mismatch explicit.
Strength scaling is the most consistent all-boss archetype, though Vantom still taxes oversized single hits.
Poison is excellent into Kaiser Crab, Lagavulin Matriarch, and The Queen, but weak into The Insatiable and Test Subject.
Doom has almost the same matchup profile as Poison for the same reason: great when debuffs persist, bad when the fight resets or clocks you.
Multi-hit decks are premium into Vantom and strong into Kin Priest and Ceremonial Beast, but they lose value when a long attrition fight needs scaling more than hit count.
Draw-heavy decks overperform against The Queen because mid-turn draw helps bypass Bind.
Boss prep starts long before the last campfire. The map preview, your current deck holes, and which status effects you can answer matter more than generic "upgrade vs rest" advice in the abstract.
Check the boss portrait on the map and draft for the fight you are actually walking into.
Upgrade damage cards if hallway survival is already stable; otherwise preserve HP first.
Save potions for the boss unless an elite will end the run before then.
Status management matters more than usual in this game. Soul Fysh and The Insatiable punish decks that cannot clear dead draws.
Apply Weak whenever possible. It meaningfully lowers damage from Ceremonial Beast, Vantom, Knowledge Demon, and the Queen's support phase.
Niepospolicie trudne walki to Kaiser Crab (Akt 2), ktory wymaga silnego skalowania, i Doormaker (Akt 3), ktory testuje zarowno atak jak i obrone jednoczesnie.
