How to Unlock and Enter the Dungeon Dimension

Entering the separate dungeon dimension requires gathering artifacts from Overworld structures and defeating an initial guardian before you can start a roguelike descent.

Finding the Fracture Shrine and Ruin

Explore the Overworld until you find a generated Fracture Shrine. Search the structure to collect the starting materials for your journey, including a Cracked Yesterglass Lens and repair items. Once you repair the lens, follow the Archive Survey Map across the Overworld to locate the hidden ancient ruin structure. Bring combat gear, food, and light sources, as the ruin holds both puzzles and a guardian fight.

Defeating the Last Curator and Opening the Gateway

Inside the ancient ruin, work through the entrance puzzles to reach the inner chamber and confront the Last Curator. Defeat the Last Curator in combat to claim its core. With the fight finished, use your items at the portal:

1. Keep both the repaired Yesterglass Lens and the Last Curator's core on hand.

2. Approach the transformed gateway inside the ruin.

3. Hold the repaired lens with the core and activate the gateway to enter the dungeon dimension and begin the first floor of your run.
