How to Find & Use Heavy Core in Minecraft

Want to get the strongest melee weapon in Minecraft or a truly unique decoration? For either of these uses and much more, you need to get the heavy core in Minecraft. It is one of the most amazing new features from the Minecraft 1.21 update that can change how you fight. Here’s how to find it.

Heavy Core in Minecraft (2024)

The heavy core is still an experimental item within the Minecraft 1.21 update. Its functionality and design are subject to change with future versions. 

What is Heavy Core in Minecraft

True to its name, Heavy Core is a mysterious dense block in Minecraft. While serving as a unique decoration, it also allows you to unlock the strongest melee weapon in the game. But, don't let its hard appearance fool you.

Unlike obsidian, the Heavy Core is not resistant to blasts and only has a resistance of 30 points. Though, its nonflammable nature makes it a great option for building unique bases.

Where Does Heavy Core Spawn

Currently, you can only get heavy core from the vault blocks in Minecraft. Here's how:

1. First, find a Trial Chamber in your world by exploring the overworld caves.

2. Then, look for a Trial Spawner that spawns the Breeze. It is always surrounded by four Tuff blocks and often spawns in large rooms.

3. Once the Breeze spawns, defeat it to collect the Trial Key from its spawner. You might have to defeat multiple mobs before you get it.

4. Alternatively, you can also explore the decorated pots and chests to collect it.

5. After collecting the key, use it on the Vault block to collect its loot. You can find vaults in long corridors of the chambers.

As per the tests by Minecraft Wiki and our verification, there is only a 2% chance of getting the Heavy Core from a vault. Moreover, you cannot reopen the same vault more than once. So, you will have to explore more than one chamber to get this rare block.

Tips to Find Trial Chambers

Here are a few tips you can use to easily locate Trial Chambers and find heavy core in Minecraft:

  • Trial Chambers often spawn away from the cave biomes of Minecraft. So, it's best to avoid lush and dripstone caves while looking for them.
  • Most chambers generate between the world height of Y=-40 and -20. Looking in this area increases your chances of finding this structure.
  • Since all chambers generate quite deep in the overworld, it's important to keep a diamond pickaxe around. It ensures that you are never trapped

Not to forget, you can use the best Minecraft Trial Chamber seeds to skip the search.

Uses of Heavy Core in Minecraft

Now that you know how to get Heavy Core in Minecraft, it's time to uncover its uses.


When you combine a Heavy Core with a Breeze rod, it results in a Mace in Minecraft. You can use this powerful melee weapon to kill most mobs with a single hit by jumping over them. Plus, there is no other way of getting this weapon which makes the Heavy Core even more desirable.


With an uncanny appearance and a size smaller than most blocks, the Heavy Core is a great option for decorations. You can use it in combination with the new copper grates in Minecraft for some really unique builds.

Cancel Explosion

While the Heavy Core has a low blast resistance, it can still shield the blocks behind it. You can place Heavy Core blocks to cancel explosions all around your blocks. But keep in mind that it doesn't help you protect entities, only blocks.

Future of Heavy Core

As you can notice, the Heavy Core in Minecraft mainly only serves as a crafting ingredient. But, that doesn't mean that it is the final form of this amazing item. With experimental updates dropping till the release date of Minecraft 1.21 update, we expect it to gain more functionality. Who knows, the mysterious element behind this core might lead us to a new dimension. Stay tuned!
