What a Beacon Does and How to Build One

A beacon in Minecraft is a block that emits a vertical light beam and grants status effects to players within its range. To build one, you need a pyramid made of iron, gold, diamond, or emerald blocks as the base, with a beacon block on top. The pyramid can be one to four layers tall — each additional layer expands the effect range and lets you stack multiple status effects at once.

The basic structure is straightforward: place your mineral blocks in a square, then place another square on top (one block smaller on each side), and keep going until you reach the beacon at the peak. A one-layer pyramid is 3×3 blocks. A four-layer pyramid is 9×9 at the bottom, 7×7 on the second layer, 5×5 on the third, and 3×3 on top, with the beacon sitting in the center of that final layer.

Key Takeaways

  • Beacons require a pyramid base made of iron, gold, diamond, or emerald blocks, with the beacon block placed on top of the pyramid.
  • A one-layer pyramid gives effects in a 20-block radius; each additional layer increases the radius by 10 blocks and unlocks a second effect slot.
  • You activate a beacon by right-clicking it and selecting which status effect you want from the menu that appears.
  • The four available effects are Speed, Haste, Resistance, and Strength, though a four-layer pyramid lets you combine two effects at once.
  • Beacons drain experience levels to activate effects — one level per effect per second — so you need a steady source of XP or the effect will stop.

Gathering the Materials You Need

The hardest part of building a beacon is collecting enough mineral blocks. A one-layer beacon needs nine blocks. A four-layer beacon needs 164 blocks total (81 + 49 + 25 + 9). You can mix types — use iron for some layers and gold for others — so you do not have to find 164 of the same mineral.

Iron is the easiest to farm. Mine iron ore with a stone pickaxe or better, smelt it in a furnace, and craft nine ingots into one block. Gold requires a pickaxe with at least iron-level material to mine. Diamond and emerald are rarer but work the same way. If you are playing on a server or in a world where others have already built beacons, you can sometimes find mineral blocks in the Nether or End, or trade with other players.

You also need one beacon block itself. Craft it from five obsidian, three glass, and one Nether star. The Nether star drops only from the Wither boss, so you will need to defeat it first. This is the real bottleneck — not the mineral blocks, but getting a Nether star.

Defeating the Wither to Get a Nether Star

The Wither is a three-headed boss that spawns when you place four soul sand blocks in a T shape and put three wither skeleton skulls on top. Wither skeletons spawn in Nether fortresses and drop their skulls when killed by a player (about a 2.5% chance per kill). You need three skulls, so expect to farm for a while.

When the Wither spawns, it has 300 health and deals heavy damage. Fight it in an open area or a large room so you have space to move. Use a sword with Sharpness, a bow with Power, or both. Healing potions are essential. Once you defeat it, it drops a Nether star, which you can pick up and use to craft the beacon block.

If you do not want to fight the Wither yourself, some servers or multiplayer worlds have shared beacons already built. You can use those effects without building your own, though you cannot control which effects are active.

Building the Pyramid Layer by Layer

Start on flat ground or a prepared platform. Lay out your first layer in a 9×9 square if you want a four-layer beacon, or smaller if you want fewer layers. Use any mix of iron, gold, diamond, or emerald blocks — the game treats them all the same.

Place the second layer centered on top of the first, making it 7×7. Then the third layer (5×5), then the fourth layer (3×3). Each layer should be centered so the pyramid looks symmetrical. The beacon block goes in the center of the top layer, sitting on top of the 3×3 square.

The pyramid does not have to be solid — you can leave gaps inside as long as the top surface of each layer is complete. This saves materials if you are building a very large beacon. However, the simplest approach is to fill each layer completely.

Activating the Beacon and Choosing Effects

Once the beacon is placed, right-click it to open the effect menu. You will see four buttons: Speed, Haste, Resistance, and Strength. Click the effect you want. The beacon will activate and emit a beam of light upward. The effect applies to all players within the radius — you do not have to stand still or stay close.

A one-layer beacon gives one effect in a 20-block radius. A two-layer beacon gives the same effect in a 30-block radius and unlocks a second effect slot, so you can stack two effects at once. A three-layer beacon extends the radius to 40 blocks and still allows two effects. A four-layer beacon reaches 50 blocks and still allows two effects.

To add a second effect on a multi-layer beacon, click the first effect, then click the second effect button. Both will activate. You can change effects at any time by right-clicking the beacon again.

Understanding the XP Cost and How to Sustain It

Beacons drain experience levels to stay active. Each effect costs one XP level per second. If you have two effects running, it costs two levels per second. Once you run out of XP, the effects stop until you gain more levels.

To keep a beacon running indefinitely, you need a steady XP farm. Mob grinders (especially enderman or creeper farms) produce XP quickly. Fishing also generates XP slowly. Mining and killing mobs by hand works but is tedious for long-term use. If you are playing casually and do not mind the effects turning off, you can just let the beacon drain your XP and reactivate it when you gain more levels.

Some players build beacons near their main base and leave them off most of the time, turning them on only when they need Speed for travel or Haste for mining. This uses far less XP than running effects constantly.

Common Beacon Mistakes and How to Avoid Them

The most common mistake is building the pyramid with the wrong blocks. Beacons only work with iron, gold, diamond, or emerald. Blocks like lapis, coal, or redstone will not work, even though they look similar. Double-check your material before you place the whole pyramid.

Another mistake is placing the beacon block in the wrong spot. It must sit on top of the pyramid, centered on the highest layer. If you place it to the side or floating above, it will not activate. The game will not give you an error message — the beacon just will not work.

Players also sometimes forget that beacons drain XP. If you activate a beacon and the effects turn off after a few seconds, you have run out of experience levels. Gain more XP by mining, killing mobs, or fishing, then reactivate the beacon.

Frequently Asked Questions

Can I use different block types in the same pyramid?

Yes. You can use iron blocks on one layer, gold on another, and diamond on a third. The game treats all four mineral types the same way for beacon purposes. Mix them however you want based on what you have available.

What happens if I build a beacon without a full pyramid?

The beacon will not activate. It needs at least a one-layer pyramid (nine blocks in a 3×3 square) directly underneath it. A beacon floating in the air or sitting on a single block will not work.

Do the effects work on other players in multiplayer?

Yes. Any player within the beacon's radius gets the effects, whether they are standing still or moving around. You do not have to be the one who built it or activated it.

Can I have more than two effects at once?

No. The maximum is two effects, and you can only stack two if your beacon has at least two layers. A one-layer beacon gives one effect only.

What if I want to move my beacon to a different location?

Break the beacon block with a pickaxe and it will drop as an item. You can pick it up and place it elsewhere. The pyramid blocks stay where they are, so you will need to break those too if you want to move the whole structure. The Nether star inside the beacon block is preserved when you break it.
