The free Vampire Survivors DLC Ante Chamber brought four weapons, one passive item, and four weapon evolutions never seen before in the game. They’re all themed after Balatro, the theme of this free update, and can be unlocked by playing the Ante Chamber Special Stage.
To get and evolve an Ante Chamber DLC weapon, you must unlock it first. For example, it’s impossible to evolve Infernolatro in your first run as Jimbo. You need to start by getting this weapon to level six, which will make it available to all characters and let you evolve it into NaneInferno in a future run.
These weapons and evolutions are initially tied to the Ante Chamber stage, so you buy a Joker Disc in Moongolow and unlock it to explore the combos. Once you do it, follow all the recipes in this guide while playing this Special Stage.
Every weapon combo in the Ante Chamber DLC
For every weapon combo, you need the Outer Saboteur item on level nine, which is its max level, and a chest to open for a chance to trigger the evolution. Every run in the Ante Chamber starts with Outer Saboteur in your inventory, so you only need to find the Base Weapons for the combo.
| Base Weapon | Passive Item | Evolution | Effect |
|---|---|---|---|
| Infernolatro | Outer Saboteur | NaneInferno | Adds a second zone. Zone effects multiply when combined |
| Fibonacci Spritz | Outer Saboteur | Royal Flush | Has a 55-percent chance to fire 1, 2, 3, or 5 other weapons. |
| Gros Michel | Outer Saboteur | Cavendish | Always crits. Always explodes. Other weapons crit more often. |
| Celestial Booster | Outer Saboteur | Negative Space | Reveals secret planets. Planets occasionally turn negative. |
I evolved all the weapons in a single run in the Ante Chamber. So, as long as you have Outer Saboteur on max level, it will let you evolve all the other Base Weapons regardless of whether you have already evolved one of them in the same attempt.
Each weapon evolution is also tied to a character unlock as follows:
- NaneInferno unlocks Canio
- Royal Flush unlocks Chicot
- Cavendish unlocks Perkeo
- Negative Space gives you 77,777 Gold Coins the first time.
