How to Craft Heavy Core in Minecraft
The Heavy Core is found in ominous trial vaults and is used to craft the mace weapon.
Overview
The Heavy Core is found in ominous trial vaults and is used to craft the mace weapon. Rather than being crafted at a workbench, heavy core is obtained through gameplay: found in ominous trial vaults. From there you use it directly in the world or as an ingredient in other recipes.
Once you have it, heavy core is used for crafting the mace. Because there is no recipe to fall back on, it is worth collecting more than you think you need whenever you come across a source, so a shortage never stalls a project mid-way.
Items like this that are gathered rather than crafted tend to gate progress: you cannot simply assemble more from raw blocks, so each one represents time spent exploring, fighting, or searching the right structure. Plan a dedicated trip to its source, bring the gear that trip demands, and bank a comfortable surplus while you are there. That way heavy core is never the thing standing between you and the recipe or task that needs it.

The only thing you need is Heavy Core (found in ominous trial vaults). Keep a few spare in your inventory, since this item is consumed wherever it is used.
Tips & Notes
- Because Heavy Core cannot be crafted, plan ahead and stockpile it when you have the chance, rather than relying on finding more at the moment you need it.

How Heavy Core Fits Your World
Building blocks are the backbone of construction, and the variant you choose changes both the look and the behaviour of a build. Stairs and slabs let you shape rooflines and half-steps, glass and stained glass let light through, and decorative stone and concrete give you a consistent palette for large projects. Many of these blocks are also craftable in bulk, which matters when a single build can swallow thousands of them. For Heavy Core specifically, that means it is most valuable for crafting the mace.
