Nether Portals & Dimensional Travel
The Nether Portal is your gateway to the run. Building it quickly and knowing where to build your exit portal is essential for a sub-hour time.
1. Portal Construction
You rarely have a diamond pickaxe. You must "cast" the portal using lava and water buckets.
The Lava Pool (Standard)
The most common method. Requires a lava pool, a water bucket, and building blocks.
- Place a block in the lava, then water against it to form the base.
- Build a 3-high pillar and a 2-block overhang ("L" shape).
- Place water at the top to flow down.
- Place lava buckets into the flowing water to form the obsidian frame.
Magma Ravines (Ocean)
In ocean runs, dive down to a magma ravine. The bubbles give you air.
- Door Method: Place a door to create an air pocket and mine obsidian (slow).
- Casting: Use the magma blocks as a base to cast the portal underwater (advanced).
2. Lighting the Portal
If you don't have Flint & Steel, don't panic.
- Fire Charge: Found in Ruined Portal chests or Piglin trades.
- Wood & Lava: Place flammable wood (planks/crafting table) next to the portal frame and place lava next to it. Wait for the fire to spread to the portal.
3. Blind Travel (The "Educated" Travel)
Instead of running thousands of blocks in the Overworld, travel through the Nether. 1 block in the Nether = 8 blocks in the Overworld.
The Math: Take your Nether coordinates (X, Z) and multiply by 8. That is where you will
emerge in the Overworld.
When to Build the Exit Portal:
Don't just build randomly. Use "Divine" travel or "Calculator" travel.
- Fossil Divine: If you find a fossil in the Nether at specific coordinates, it can point to the Stronghold location.
- Rough Estimate: Most Strongholds generate in the "first ring" (1200-2000 blocks from 0,0). Travel to ~200 Nether coordinates (X or Z) to be in the ring.
