How to Build a Dungeon Portal in the Overworld

Before you can enter the dungeon dimension, you need to build a custom portal structure anywhere in the Overworld. Because all dungeons exist in a single separate dimension, one portal frame at your base can connect to endless generated runs.

Crafting the Portal Blocks

Gather stone bricks, gold ingots, and an Eye of Ender from your normal survival progression, then head to a Crafting Table:

1. Craft Gilded Portal Blocks: Combine gold ingots and stone bricks to make the decorative blocks needed for the portal's outer frame.

2. Craft the Portal Keyhole Block (Portal Keystone): Combine a Gilded Portal Block with an Eye of Ender. This central block holds the keys that open your gateway.

Assembling the Portal Structure

Pick a safe spot in your base, an underground room, or a cave:

1. Place standard building blocks and your Gilded Portal Blocks to construct the custom upright portal doorway.

2. Place the Portal Keyhole Block directly into the top of the frame where it can accept keys.

3. Check the structure closely; an incomplete or unactivated portal will sit idle or emit smoke if built improperly.

Once the frame is standing, it will remain inactive until you insert an activated key into the keyhole block. You can leave this single frame in place permanently and swap keys whenever you want to visit a different dungeon.
