Update 1.11 added a new stage to Vampire Survivors called Room 1665, and you only need to type a simple spell in the Secrets menu to unlock it. But if you haven’t found the Forbidden Scrolls of Morbane Relic yet, you won’t be able to access it.
How to unlock the Secrets menu in Vampire Survivors
To get the Forbidden Scrolls of Morbane Relic, you need to defeat the boss in the Bone Zone stage. When you open the map, you’ll see an interrogation point, which is where the boss will be—but don’t go straight to it. If you can’t find the boss anywhere on the map, you need to unlock Moonglow first.
The boss is a rolling ball made of skulls and bones that gets bigger and stronger as it collides with the mobs. Because of that, we recommend playing with a character that has at least 20 percent movement speed, otherwise, you won’t be able to catch up with the ball.
Before you head down to attack the boss, play like you normally would with any build until you have leveled up and possibly evolved all your weapons. The boss only grows when it’s on your screen, so if you face it too early, you’ll easily get overwhelmed by its size plus the mobs around you.
Go with a character that levels up fast in the beginning like Imelda or Poppea and get the Crown to to speed up the process. The weapons are up to you, but we recommend high-damage weapons such as the Axe and the Fire Wand, as well as an item that restores health because you won’t find any consumables on the map, only gold.
For the Arcana, the Waltz of Pearls and Iron Blue Will pair well with the Fire Wand and Axe respectively, as well as the Boogaloo of Illusions so their damage covers a bigger area. Prioritize the Waltz of Pearls and Iron Blue Will because without them is harder to hit the boss.
Be patient when you find the boss in the Bone Zone. Keep the mobs from reaching the ball so you can deal damage without it getting bigger and you’ll defeat it eventually. It will drop the Forbidden Scrolls of Morbane Relic and once you get it, you can quit to the main menu. you’ll see a “Secrets” button at the bottom left corner, that’s where you’ll unlock Room 1665 in Vampire Survivors.
How to unlock Room 1665 in Vampire Survivors
In the Secrets menu, type “forbiddenbox” using a keyboard or using the in-game keyboard by clicking on the “ABC” button. As you type the last letter, you’ll be instantly teleported to Room 1665 as the previous character you used.
This stage isn’t just one room, it’s a series of rooms that open as you defeat around 100 enemies. Connecting each room is a corridor with light sources that will help you survive until you reach the last room to find the Darkasso relic.
After you complete or die for the first time Room 1665, it will be available in the stage list without the need to insert the code again in the Secrets menu.
