Doormaker is a boss in Slay the Spire 2. Here is what she or he does, the moves to expect, and the order that actually wins.
A two-phase repeating boss: you break through the Door (155 HP), then face the Doormaker itself. It cycles between Door and Doormaker forms, gaining Strength each cycle.
Heads up — this boss is no longer current. As of patch 0.107.1, Aeonglass replaced the Doormaker as the Act 3 Glory boss. This page is kept because older guides and wikis still link to it, but if you are fighting the current Act 3 boss, read the Aeonglass guide instead.

How to beat Doormaker
- Burst through each Door phase as quickly as possible to maximize your damage during the Stun window. The Doormaker’s Strength stacks each cycle, so you want as few cycles as possible. Save your biggest damage for the Stun turn — it’s your main window. Block heavily on the attack turns. Consistent sustained damage is better than slow setup here.
- The Stun turn after breaking the Door is your best damage window — use it
- Each cycle adds Strength, so the fight gets harder the longer it goes
- You need ~644 total damage (155 Door + 489 Doormaker) — plan accordingly
- Save heavy Block for the Big Swing turn before the Door reforms
