You finally did it. You braved the soul sand valleys, dodged those annoying blazes, and decapitated enough Wither Skeletons to summon the boss. After a chaotic fight with the Wither—hopefully one where it didn't blow up your favorite storage room—you’re holding that shiny, pulsating Nether Star. Now comes the part that actually matters. You need to know how to set up a beacon in Minecraft without wasting half your day or, worse, all your precious iron blocks on a setup that doesn't even work.
It's a flex. Let's be real. Seeing that beam of light shooting into the sky from miles away tells everyone on the server that you’ve made it. But it's also about the buffs. Whether you want to mine out an entire chunk in twenty minutes with Haste II or you just want to stop dying to fall damage around your base with Resistance, the beacon is the ultimate endgame tool.
The Anatomy of a Powerhouse
A beacon isn't just a block you plop on the ground. It’s the "engine," but it needs a "chassis." That chassis is a pyramid. You can't use just any block, though. Forget wood, dirt, or even obsidian. You need the heavy hitters: Iron, Gold, Diamond, Emerald, or Netherite blocks. Most players stick with iron because, honestly, who has enough Netherite to build a full-size pyramid? If you do, I’m scared of you.
The beacon block itself is a craftable item. You’ll need five glass blocks, three obsidian blocks, and that hard-earned Nether Star. Once you’ve got the beacon block, you have to build the base. This is where people start getting confused about the layers.
Building the Pyramid Layers
You have four potential levels. A single-level pyramid is just a 3x3 square of blocks with the beacon in the dead center. This gives you the basic range and the weakest buffs. If you want the real power—the stuff like Haste II or Strength—you need a full four-tier pyramid.
Here’s how the math breaks down. The top layer is 3x3. Under that, you need a 5x5 layer. Below that, 7x7. And for the grand finale, the bottom layer is 9x9. Total? That’s 164 blocks of solid metal or gems. If you’re using iron, that’s 1,476 iron ingots. It’s a massive investment, but it’s the difference between a decorative light and a game-changing power station.
A common mistake is thinking you have to fill the inside. Yes, the pyramid must be solid. No hollow centers. The beacon won't activate if there's a gap in the middle of those layers. Minecraft checks for a solid foundation.

Lighting the Beam
The beacon needs a clear view of the sky. This is non-negotiable. If you build it underground, you have to dig a hole all the way to the surface. Bedrock is the only "block" that the beam can pass through in the Java Edition, which is why you can technically build beacons on the roof of the Nether, but for your overworld base, just keep the path clear.
What about glass? You can actually change the color of the beam by placing stained glass on top of it. If you stack different colors, the beam will blend them. It’s a great way to mark different zones of your base or just show off your aesthetic taste.
Activating the Buffs
Once the beam is firing, you aren't done. You have to "pay" to turn on the effects. When you right-click the beacon, you’ll see a UI with slots for primary and secondary powers. You need to toss in a single ingot—Iron, Gold, Netherite, or an Emerald/Diamond—to lock in your choice.
The primary powers are:
- Speed: Walk and run faster. Great for massive builds.
- Haste: Swing your pickaxe like a madman. Essential for "instamining."
- Resistance: Take less damage from basically everything.
- Jump Boost: Leap over fences and small hills with ease.
- Strength: Hit harder. Self-explanatory.
If you have a full four-tier pyramid, you unlock the secondary power slot. This is where you can either choose Regeneration (highly recommended) or upgrade your primary power to Level II. Haste II is the gold standard here. Combine Haste II with an Efficiency V Netherite Pickaxe, and you will chew through stone like it’s butter.

Range and Logistics
The beacon doesn't cover the whole world. A full-tier pyramid gives you a range of 50 blocks in every direction from the center. That sounds like a lot until you realize how fast you can run 50 blocks. If you have a sprawling mega-base, you’re going to need multiple beacons.
The interesting part is that you can "overlap" beacons. You don't need a separate 9x9 pyramid for every single beacon. You can build a wide rectangular base and place multiple beacon blocks on the top 3x3 area. This is a pro-move because it saves you hundreds of blocks of iron. A "6-pack" beacon setup is the ultimate endgame goal for many players, providing every single buff simultaneously within a massive area.
Troubleshooting Your Setup
If your beacon isn't lighting up, check the "obstruction" rule first. Is there a stray leaf block from a nearby tree hanging over it? Is there a carpet in the way? While some transparent blocks are okay, most will kill the beam instantly.
Second, check the base. Is it actually solid? A single missing block in the 7x7 layer will break the whole thing. Also, make sure you aren't trying to use "Raw" ore blocks. They have to be the refined metal blocks. I've seen people try to build them out of Raw Iron blocks, and it just doesn't work.

Actionable Next Steps
Setting up a beacon in Minecraft is a milestone that changes how you play the game. It turns "grinding" into "efficiency."
- Audit your iron supply. If you don't have 164 blocks, go build an iron farm or spend a few hours at Y-level 16.
- Pick your spot. Locate the center of your base or the area where you do the most building.
- Dig your sky-hole. If you're building underground, ensure the vertical column above the beacon is completely air or glass.
- Secure the Nether Star. If you haven't fought the Wither yet, do it in an enclosed space like under the End portal fountain to make the fight trivial.
- Commit to Haste II. For your first beacon, don't get distracted by Jump Boost. Haste II is the most functional upgrade for any player looking to expand their world.
The beacon is more than just a light. It’s a statement of dominance over the game’s mechanics. Once you experience the speed of Haste II, there is no going back to "normal" mining.
