A beacon requires an iron, gold, diamond, or emerald pyramid base plus a beacon block on top

A beacon in Minecraft is a block that gives nearby players status effects like Speed, Haste, Resistance, Jump Boost, or Strength. To make one work, you stack mineral blocks in a pyramid shape — the bigger the pyramid, the more effects you can set up at once. The beacon block itself sits on top of the pyramid and needs a clear line of sight to the sky to function.

You can build a beacon with iron blocks, gold blocks, diamond blocks, or emerald blocks, or mix them together. A one-level pyramid is 3×3 blocks. A two-level pyramid sits on a 5×5 base with a 3×3 layer on top. A three-level pyramid is 7×7, then 5×5, then 3×3. A four-level pyramid reaches 9×9 at the base. Each level you add unlocks one more effect slot, up to two effects at the largest size.

Key Takeaways

  • Beacons require a pyramid of mineral blocks (iron, gold, diamond, or emerald) with the beacon block placed on the very top.
  • A one-level pyramid activates one effect; each additional level lets you choose a second effect from the same list.
  • The beacon must have an unobstructed view of the sky — no blocks directly above it — or it will not set up.
  • You power a beacon by placing a mineral block in the item slot at the top of the beacon's interface, then selecting which effect you want.
  • The effect radius expands with each pyramid level, reaching 50 blocks at the largest four-level size.

Gathering the materials you need

You need one beacon block, which you craft from five obsidian, three glass, and one nether star. The nether star drops only from the Wither boss, so defeating the Wither is the main bottleneck. You summon the Wither by placing three soul sand blocks in a T shape and putting three wither skeleton skulls on top — you find wither skeletons in Nether fortresses.

For the pyramid itself, collect mineral blocks. Iron blocks are the easiest to farm if you have a mob grinder or access to iron ore. Gold blocks require more mining but are faster to collect if you find a gold farm. Diamond and emerald blocks are the rarest but work just as well. You do not need to use the same material for every level — a 7×7 base of iron with a 5×5 layer of gold and a 3×3 layer of diamonds works perfectly fine.

Calculate how many blocks you need before you start building. A one-level pyramid needs 9 blocks. A two-level pyramid needs 9 + 25 = 34 blocks total. A three-level pyramid needs 9 + 25 + 49 = 83 blocks. A four-level pyramid needs 9 + 25 + 49 + 81 = 164 blocks. If you are building a four-level beacon with iron blocks, that is 164 iron blocks plus one beacon block.

Building the pyramid structure

Start with the largest layer at the bottom. If you are building a four-level beacon, place a 9×9 square of mineral blocks. Mark out the corners first so you do not lose track of the size. Use a crafting grid or mental math to keep the layers centered — each layer should be 2 blocks smaller on each side than the layer below it.

Stack the second layer (7×7) directly on top of the first, centered. Then the third layer (5×5), then the fourth layer (3×3). The beacon block goes on top of the 3×3 layer, in the center. Make sure the beacon block is exposed to the sky with no blocks above it — even a single block overhead will prevent it from working.

You can build the pyramid anywhere in the Overworld, the Nether, or the End, as long as the beacon has sky access. Underground beacons work if you dig a shaft straight up to the surface. Beacons do not work in the Nether or End if there is no sky above them in those dimensions.

Activating the beacon with a power source

Once the pyramid is built, right-click the beacon block to open its interface. You will see a small square slot at the top — this is where you place a mineral block to power the beacon. Drop an iron, gold, diamond, or emerald block into that slot. The block does not have to match the pyramid material.

After you place a power block, the interface shows you the available effects. For a one-level pyramid, you see one row of five effects: Speed, Haste, Resistance, Jump Boost, and Strength. Select the effect you want by clicking it. The beacon will now emit a beam of light and explore that effect to all players within range.

For a two-level pyramid, you get two effect slots. Select a primary effect in the first row, then select a secondary effect in the second row. The secondary effect can be the same as the primary or different. A three-level pyramid lets you choose two effects, and a four-level pyramid also lets you choose two effects — the difference is the range and the strength of the effect.

Understanding effect ranges and durations

The effect radius depends on how many levels your pyramid has. A one-level pyramid affects players within 30 blocks. A two-level pyramid reaches 40 blocks. A three-level pyramid reaches 50 blocks. A four-level pyramid also reaches 50 blocks — the range caps at 50 blocks, but the effect strength increases with each level.

Effects stay active as long as you are within range and the beacon has a power block in its slot. If you leave the range, the effect lasts for a few more seconds, then fades. If you remove the power block, the effect stops when ready. The beacon does not consume the power block — you can use the same block over and over.

Speed and Haste effects are most useful for mining or traveling. Resistance reduces all damage except starvation and the void. Jump Boost lets you jump higher, useful for parkour or crossing gaps. Strength adds damage to melee attacks. You can run multiple beacons at once if you want to stack effects — a player in range of two beacons gets both effects simultaneously.

Troubleshooting a beacon that will not set up

If your beacon is not glowing or explore effects, the most common cause is a block directly above it blocking the sky. Check straight up from the beacon block — even a single block, a slab, or a trapdoor will prevent set up. Remove anything above the beacon and try again.

The second most common issue is an incomplete or misaligned pyramid. Count your blocks carefully and make sure each layer is centered on the one below. A 9×9 base with a 7×7 layer on top is wrong — it should be 9×9, then 7×7, then 5×5, then 3×3. If the layers are off by even one block, the beacon will not recognize the pyramid.

If the pyramid is correct and the sky is clear, check that you have placed a power block in the beacon's item slot. The slot is small and straightforward to miss. Right-click the beacon, look for the square at the top of the interface, and place a mineral block there. If you still see no beam, try placing a different type of mineral block — though all types work, occasionally a visual glitch clears by switching materials.

Building beacon farms for multiple effects

Many players build beacon farms with multiple beacons stacked or placed side by side to cover large areas or provide multiple effects at once. You can place beacons directly next to each other, and their ranges overlap. A player standing between two beacons gets both effects even if each beacon is only 30 blocks away.

Some players build a single massive pyramid with multiple beacon blocks on top, each powered separately. This is more efficient than building four separate pyramids because you share the mineral block cost. A 9×9 base can support up to four beacon blocks on top if you arrange them in a 2×2 pattern, though only the center block has a clear sky view in most designs.

For mining operations, a beacon farm with Speed and Haste is standard. For combat arenas, Strength and Resistance are common. For parkour courses, Jump Boost is essential. Plan your farm around what effects you actually use — a single beacon with Speed is often enough for most players.

Frequently Asked Questions

Can I use a beacon in Creative mode?

Yes. Beacons work identically in Creative and Survival modes. In Creative, you can grab beacon blocks and mineral blocks directly from the inventory without crafting or mining, so building a beacon farm is much faster for testing designs.

What happens if I break the pyramid after the beacon is active?

The beacon stops working when ready. The effect fades within a few seconds. You can rebuild the pyramid and the beacon will reactivate as soon as the structure is complete and the power block is in place.

Do beacons work underwater or in rain?

Yes. Water and rain do not block the sky view. A beacon at the bottom of the ocean works fine as long as there are no solid blocks directly above it.

Can I use the same mineral block type for the entire pyramid?

Yes. You can build a beacon entirely from iron blocks, or entirely from gold, diamond, or emerald. Mixing types works too — there is no penalty for mixing, and it can save resources if you have some materials more readily available than others.

How much does a beacon cost in terms of resources?

The beacon block itself requires defeating the Wither, which is the main cost. A four-level pyramid with iron blocks costs 164 iron blocks plus the beacon. If you use diamond blocks instead, that is 164 diamonds. Most players consider the Wither fight the real bottleneck, not the mineral blocks.
