You finally killed the Wither. It took three skulls, a bunch of soul sand, and probably a few frantic deaths in a narrow tunnel, but you have the Nether Star. Now comes the part where most players get stuck: actually making it work. Learning how to activate a beacon minecraft isn't just about placing the block and hoping for the best. It’s a resource sink. If you don't do it right, you’re just staring at a very expensive piece of glass that does absolutely nothing.
Beacons are the peak of late-game survival. They offer buffs that make you feel like a god—Haste II allows you to instamine stone, and Strength II makes mobs a joke. But the cost is staggering. We’re talking stacks of iron, gold, emeralds, or diamonds. Most people go with iron because, honestly, who has 1,476 diamonds just lying around? Even with a massive iron farm, the setup takes focus.
The Pyramid is Everything
You can't just slap a beacon on the dirt. It needs a base. This base must be made of specific mineral blocks: Iron, Gold, Diamond, Emerald, or Netherite. Don't mix them if you care about aesthetics, though the game doesn't actually mind if you do. A "Frankenstein" pyramid of gold and iron works just as well as a pure emerald one.
The structure is a pyramid. A full-power beacon requires four layers.
The bottom layer is a 9x9 square of blocks. On top of that, you center a 7x7 square. Then a 5x5. Finally, the top layer—the one the beacon actually sits on—is a 3x3 square. That’s a total of 164 blocks. If you’re using iron, that is 1,476 iron ingots. It’s a lot. If you're just starting and don't have those resources, you can build a single-layer version with just the 3x3 base. It works. You just won't get the high-tier powers like Regeneration or the level II buffs.
Why Your Beacon Isn't Lighting Up
So you built the pyramid. You placed the beacon in the dead center of the 3x3 top layer. And... nothing. No beam. No GUI options. This is usually where the frustration sets in.

Check your sky access.
Minecraft is very picky about what is above a beacon. You need a clear view of the sky. "Clear" is a relative term here. Glass is fine. Tinted glass is fine (and it actually changes the beam color). Even bedrock in the Nether doesn't stop it if you’re playing on certain versions, but generally, if there is a solid block—stone, dirt, wood—anywhere in the vertical column above the beacon, the beam will fail.
Also, check the pyramid's integrity. If there is a single hole inside that pyramid, or if you accidentally used a block of Raw Iron instead of a finished Iron Block, the beacon stays dead. It has to be solid mineral blocks. No hollow centers. No shortcuts.
Choosing Your Powers Wisely
Once the beam is shooting into the atmosphere, right-click the beacon. You’ll see a menu with primary and secondary powers. To activate them, you have to "pay" the beacon. You can use one Iron Ingot, one Gold Ingot, one Emerald, or one Diamond. One Netherite Ingot works too, but please don't do that. It’s a waste of the rarest material in the game for a result you can get with a piece of iron you found in a shipwreck.
The powers depend on the pyramid height:

- Level 1 (1 Layer): Speed or Haste.
- Level 2 (2 Layers): Resistance or Jump Boost.
- Level 3 (3 Layers): Strength.
- Level 4 (4 Layers): This unlocks the "Secondary Power" slot.
Most players aim for Haste II. To get it, you need a full 4-layer pyramid. You select Haste in the primary column and then click the Haste icon again in the secondary column (or pick Regeneration). If you don't select that second icon, you’re stuck with Haste I, which is fine, but it won't let you tear through deepslate like it’s butter.
The Math of Efficiency
Let’s talk about the range. A 1-layer beacon covers a 20-block radius. That’s tiny. A full 4-layer beacon covers 50 blocks from the base. This is a square area, not a circle. It also extends infinitely upwards but only 50 blocks downwards. This is a massive detail people miss. If you build your beacon at sea level (Y=64) and your mine is at Y=-58, the buff will run out before you even hit the deepslate layers.
If you want a beacon for mining, you have to bury it.
Dig a hole. Drop the pyramid down near the bottom of the world. Then, you have to clear a 1x1 shaft all the way to the surface so the beam can see the sky. It’s a pain, but it's the only way to keep Haste II active while you’re hunting for diamonds.
Multi-Beacons: The Pro Strategy
If you want all the buffs at once, don't build six separate pyramids. That’s a nightmare. Instead, you can overlap them. A "6-beacon" base uses a 10x11 bottom layer instead of a 9x9. By sharing the base blocks, you save hundreds of resources. You end up with a rectangular platform on top where six beacons sit side-by-side.

It looks intimidating. It is. But if you have an iron farm or a gold farm in the Nether, it’s the only way to go. Having Speed II, Haste II, Strength II, and Resistance all hitting you at once makes you practically invincible within your base's perimeter.
Aesthetics and Tints
The default white beam is classic, but it’s a bit boring. You can change the color by placing stained glass blocks or panes anywhere above the beacon. The beam will pass through and take on the color.
Here’s a trick: stack the glass. If you put a red glass block and then a blue one above it, the colors mix. You can get thousands of variations by layering different stained glass colors. It doesn’t affect the power or the range; it’s just for show. But in a game about building, show matters.
Common Misconceptions and Limitations
I see people trying to use "Silk Touch" on a beacon thinking they can move the whole pyramid. Nope. You have to break it all down and rebuild it block by block. It’s tedious.
Another big one: the "Payment" isn't a subscription. You pay once to set the power. It stays that way forever until you decide to change the power. If you change from Haste to Speed, you have to pay another ingot. But as long as the pyramid is intact and the sky is clear, those buffs will pulse every few seconds indefinitely.
Keep in mind that the "pulse" is what actually gives you the effect. The effect lasts for about 11-17 seconds and refreshes every 4 seconds. If you step out of range, you don't lose the power instantly. You have a small "buffer" time to run back in.
Actionable Steps for Your First Activation
- Secure the Star: Kill the Wither. If you’re struggling, spawn him in a cramped cave or under the End portal fountain to cheese the fight.
- Farm the Iron: Don't even try a full beacon without an iron farm. You need 1,476 ingots. Manual mining will take you hours of soul-crushing labor.
- Clear the Space: Find the center of your base or mine. Ensure there’s a vertical line to the sky.
- Build from the Top Down (Mentally): It’s easier to visualize. Start with the 3x3. If you have more blocks, add the 5x5 under it.
- Feed the Machine: Use an emerald or iron ingot to select your buff. Always prioritize Haste if you’re building or Speed if you’re traversing.
Setting up a beacon is a rite of passage. It marks the transition from "surviving" to "dominating" the world. Once that beam hits the sky, the game changes. Just make sure you don't leave a dirt block over it by accident. It happens to the best of us.
