Slay the Spire 2 Queen Strategy Guide: How to Beat the Queen
The Queen is one of the toughest Act 3 bosses in Slay the Spire 2, mostly because the fight starts in a strange way. She hides behind a massive summon while stacking brutal debuffs that last the entire battle. Once you understand the order of the fight and deal with the summon correctly, the encounter becomes much more manageable.
Queen Boss Strategy In Slay The Spire 2
To beat the Queen in Slay the Spire 2, kill her summon first while setting up your deck, then burst the Queen down quickly once she enters the fight.
The fight is split into two clear phases. The first phase revolves around destroying her summoned creature. The second phase is a straight boss fight against the Queen herself.
The main challenge comes from the permanent debuffs she places on you early in the fight. These debuffs stay for the full battle, so the goal is to scale your damage fast and end the fight before things spiral out of control.
Phase 1: Taking Down The Queen’s Summon
The battle always begins with the Queen hiding behind a large summon. This creature has a very high health pool and acts as the main source of damage early on.
The summon deals heavy attacks every turn, usually between 20 and 40 damage. That pressure adds up quickly if you do not control it. Applying Weak to the summon can help a lot here since it cuts the damage while you prepare your deck.
During this phase the Queen does not attack directly. Instead she applies huge debuffs like Frail, Weak, and Vulnerable that last 99 turns. In other words, the entire fight. She also gains Shield each turn, so damaging her directly is not realistic while the summon is alive.
A good approach here is to treat the summon like a setup window.
Apply Weak to the summon to reduce incoming damage
Build your scaling cards and powers
Prepare burst damage for the next phase
Finish the summon before its damage ramps too high
The summon gains extra damage every turn, so leaving it alive too long becomes dangerous. Most decks want to finish it around turn 7 to 10.
Phase 2: Fighting The Queen Directly
Once the summon dies, the Queen finally enters the fight. She has around 400 health and follows a predictable move pattern.
Her attack cycle usually goes in this order.
Damage buff
Multi hit attack
Single heavy attack
This predictable rotation actually makes the fight easier to plan around. You can prepare defense for the heavy turns and push damage during her buff turn.
The biggest issue here is that you are still suffering from the 99 turn debuffs. Frail means your Block generation is weaker than normal. Because of that, Weak becomes extremely valuable.
Reducing her damage with Weak often works better than trying to stack huge Block numbers.
If your deck has strong scaling or burst damage, the Queen usually falls quickly once phase two begins. The fight is basically a test of how well your deck came together during the run.
One Shot Strategy Against The Queen
There is also a rare strategy that can delete the Queen instantly. It requires a specific setup with the Necrobinder.
The idea is to scale a single attack card to massive damage before reaching Act 3. Then you stack effects that allow the attack to trigger multiple times in one turn.
A typical setup looks like this.
Play Necrobinder
Scale damage using The Scythe across multiple fights
Add Innate so the card always starts in your hand
Use relics or effects that duplicate your first card
Combine with a duplication potion
If The Scythe reaches very high damage, the duplicated attacks can deal hundreds of damage instantly. When everything lines up, the Queen can disappear in a single turn. It is rare, but very funny when it works.
Final Blurb
The Queen looks terrifying the first time you run into her, mostly because the fight starts in an unusual way. The key is realizing the summon phase is actually a setup window. Build your engine, kill the summon, then burst the Queen before her attacks get out of hand.
Once you understand the two phase structure, the fight becomes far less intimidating. And if you ever one shot her with a ridiculous combo, congratulations. The Spire probably deserved that.

The Queen is one of the bosses that can appear at the end of Act 3. She begins the battle behind a powerful summon and applies long lasting debuffs before entering the fight herself.
What should you target first in the Queen fight
Always kill the summon first. The Queen cannot properly engage in the fight until the summon dies, which gives you time to prepare your deck.
Why are the debuffs so dangerous in this fight
The Queen applies Frail, Weak, and Vulnerable for 99 turns. That effectively means the entire battle, which makes defense and damage scaling much harder.
What decks work well against the Queen
Decks with strong burst damage or scaling tend to perform best. Weak application is also extremely valuable because it reduces the huge damage from her attacks.
