You finally killed the Wither. It was a mess, your armor is trashed, and you have that weird, pulsing Nether Star sitting in your inventory. Now comes the part where most players get stuck: actually getting the thing to turn on. Figuring out how to make a beacon work isn't just about plopping a glass block on the ground and hoping for the best. It’s a literal pyramid scheme. If you don't build the base exactly right, that beam of light is never going to hit the sky.
Honestly, beacons are one of the most misunderstood mechanics in Minecraft. People think they can just shove some iron blocks in a hole and get Haste II instantly. It doesn't work like that. You need a specific geometry, a massive amount of resources, and a clear line of sight to the "sky" (even if that sky is just a hole in the ceiling of the Nether).
The Base is Everything
The most common reason a beacon fails to activate is a hollow base. You can’t just build a ring of blocks. It has to be a solid chunk of mineral blocks. You've got options here: iron, gold, diamond, emerald, or netherite. Most sane people use iron because raiding a few buried treasures or setting up a basic iron farm is way easier than mining enough emeralds to fill a pyramid.
A level-one beacon requires a 3x3 square of blocks. That’s nine blocks total. Once you place the beacon block in the dead center of that 3x3 square, the beam should shoot up within a second or two. If it doesn't? Check for "obstructions." Minecraft is very picky about what counts as a clear view of the sky. Glass is fine. Bedrock is not. If you are building this underground, you need to mine a 1x1 shaft all the way to the surface.

Scaling Up for Better Powers
A 3x3 base is fine if you just want a night light, but it only gives you the basic stuff like Speed I or Haste I. To get the real benefits, you have to go bigger.
The full-power pyramid is a four-tier beast. It starts with a 9x9 layer on the bottom, then a 7x7, then a 5x5, and finally that 3x3 top layer where the beacon sits. That is a staggering 164 blocks of iron, gold, or whatever you’re using. If you’re using iron blocks, that’s 1,476 iron ingots. It’s a grind. But once you have that fourth tier, you unlock Strength and, more importantly, the ability to upgrade your primary power to Level II or add Regeneration as a permanent secondary buff.
I’ve seen players try to mix and match blocks. You can actually do that. You can have a base made of iron with a single diamond block in the corner because you ran out of iron. The beacon doesn't care about the "purity" of the mineral; it just cares that the blocks are from the approved list of valuables.

Why Your Beam Won't Turn On
Sometimes you do everything right and the beam still stays dark. It's frustrating. Here is the checklist of things that usually go wrong:
- The "Sky" Rule: Even a single leaf block from a tree can block a beacon. If there is a solid block anywhere in the vertical column above the beacon, it stays off.
- The "Solid" Rule: As mentioned, the pyramid cannot be hollow. It must be a solid mass of mineral blocks.
- Bedrock in the Nether: If you're building in the Nether, you have to break the bedrock at the ceiling or find a spot where the beacon can see through to the "void" above.
- Redstone Interference: If a beacon receives a redstone signal, it shuts off. Make sure you didn't accidentally run a wire next to it.
Activating the GUI
Once the beam is active, you aren't done. You have to "pay" the beacon to give you the buffs. You need to click on the beacon to open its interface. You'll see two slots: one for the power you want and one for the payment. You can use an iron ingot, a gold ingot, an emerald, or a diamond.
Pick your power—say, Haste—and then put your ingot in the slot and click the green checkmark. If you have a full four-tier pyramid, you can click the "Haste" icon and then click the "Level II" icon (usually looks like a Roman numeral II) to boost the effect.

Strategic Placement
Where you put this thing matters. A full-tier beacon has a range of about 50 blocks. That sounds like a lot, but if you’re mining a massive perimeter, you’ll run out of that range faster than you think.
Expert players often build "multi-beacons." Instead of building separate pyramids for every single beacon, you can share the base. For example, a 10x11 base can support six different beacons at once. This saves a massive amount of resources. You get Speed, Haste, Resistance, Jump Boost, and Strength all at the same time. It makes you feel like a god in your own world.
Changing the Color
This is purely for aesthetics, but it’s a big part of how to make a beacon work for your base's "vibe." If you place a stained glass block anywhere in the beam's path, the entire beam changes color. You can even stack different colored glass panes to create custom gradients or transition colors. It doesn't affect the powers at all, but a purple beam hitting the sky looks way cooler than the default white.
The real trick is using glass panes instead of blocks. If you use a pane, it's almost invisible, but the beam still changes. It's a neat way to hide the "source" of the color change.
Actionable Next Steps for Beacon Success
- Gather exactly 164 iron blocks if you want the maximum range and secondary powers. If you’re short on resources, start with a 3x3 (9 blocks) and expand as you go.
- Clear a 1x1 vertical shaft directly above where the beacon will sit. Ensure no "solid" blocks (stone, dirt, wood) are in the way.
- Construct the pyramid layers from the bottom up: 9x9, then 7x7, then 5x5, then 3x3. Ensure every single block is filled in—no air pockets.
- Place the Beacon on the center block of the 3x3 top layer.
- Feed the Beacon one ingot (Iron, Gold, Emerald, or Diamond) to select your primary and secondary status effects.
- Check your status icons on the right side of your screen to confirm the "Haste" or "Speed" timer is constantly refreshing. If the timer counts down and disappears, you've wandered out of the 50-block radius.
