The Doormaker is a unique multi-stage boss in Act Three of Slay the Spire 2. Unlike normal enemies, it hides behind minions, giving you a very narrow window to strike back. Dealing with these distractions while waiting for your chance to attack is what makes this fight so hard. Do you want to face it with a fully developed deck right away? You can Buy Slay the Spire 2 Account on Z2U and jump straight into the action.

At the start of the encounter, the Doormaker remains off-screen, requiring you to battle through a proxy called the Door first. This mini boss, resembling a floating pile of rubble, has 155 health and punishing attacks that deal 15-30 damage per turn, split between one strong blow or two moderate hits. To survive this phase, it is essential to bring cards that provide high immediate shields. The Defect benefits greatly from Boot Sequence, while the Ironclad can use Iron Wave to generate block while dealing damage.
A smart strategy is to delay killing the Door until the beginning of your next turn when it is at low health. This ensures you have maximum energy to strike the Doormaker as soon as it emerges, keeping its buffs in check. The Doormaker is arguably more threatening, as it enhances both itself and its summoned Doors. Early in the fight, invest in powers or stat boosts to build long-term advantage. Cards like Buffer are excellent for mitigating the Door's initial heavy strikes. Be prepared to face the Door multiple times, as it reappears throughout the battle.

When the Door falls, the Doormaker emerges stunned for one full turn, giving you a perfect window to strike hard without needing to block. Use this turn to unleash your strongest attacks or stack powers and buffs for maximum advantage. Making the most of this stun is vital, because afterward the Doormaker starts fighting back with a massive 489 health pool. This boss demands heavy firepower, so load up on quick, hard-hitting cards before the encounter. Since it gradually buffs itself, dragging the fight out will only work against you.
The Doormaker attacks for two turns, hitting for about 30 damage then 40 damage in successive turns. After attacking, it disappears and summons a new Door with 20 additional health. The worst part is that it buffs both itself and the new Door with extra power as it leaves. This means you have a strict three-turn window to deal damage each time the Doormaker is visible before facing an even tougher Door. Speed is everything here, making this one fight where the Defect struggles. The Silent thrives with its free attacks and consistent card draw, while the Ironclad powers through with raw damage and strength buffs. Bringing attack potions and aggressive relics into this fight gives you a significant edge.
Aim to finish the Doormaker in three to five phases, which translates to nine to fifteen total turns to deal 489 damage. That requires roughly 20 to 40 damage per turn consistently. It is easy to get buried under the escalating Door attacks, but staying aggressive is the answer. The secret to victory is simple: do not try to pick the lock. Just kick the door down with overwhelming force.

Defeating the Doormaker requires patience, aggressive deck building, and precise turn management. You need to capitalize on its stunned turns, survive the escalating Door minions, and maintain consistent damage output across multiple phases.
