What it does

The Heavy Core is normally obtained from trial chambers, and this mod gives it a crafting recipe so players can make one at a crafting table. The recipe takes one ominous trial key, four breeze rods and four iron blocks as ingredients, which lets survival players get the item without relying on chamber loot.

Only the server needs the mod, so players can join a server running it without installing anything. Installing it on a client is optional. Files are published for Fabric, Forge, NeoForge and Quilt, and as a data pack for server platforms, with builds covering 1.21 – 26.2 across 16 release versions. The latest file for every loader is 1.0+mod for 26.2, dated 2026-07-27. Snapshot builds are published as well.

The code is released under the MIT License, but the project is not open source. The author maintains a public issue tracker for bug reports.

Use cases

Survival progression

Players who have an ominous trial key and a supply of breeze rods and iron can craft a Heavy Core without searching for another chamber.

Who it’s for: Server owners who want the Heavy Core available through crafting, and players who would rather craft it than wait for it to drop.

How it compares

Full comparison

Heavy Core Recipe is also a mod for Fabric, Forge, NeoForge and Quilt across 1.21 – 26.3, under All rights reserved, and it is needed on the server, with the client optional. Ominous Trial Key Recipe covers the same loaders and version span but adds a recipe for the trial key rather than the Heavy Core, under the same terms. Recipe heavy core targets NeoForge only, for 1.21.1, under the Apache License 2.0, and it runs on the server alone with players joining without it.
