NeoForgeClient and serverAll rights reserved1.21.4

What it does

Ruby Ore spawns in the Overworld and can be smelted into Ruby Ingots, which serve as a refined crafting material. The mod also adds a generated Ruby House structure with ruby-themed features and a custom 36-slot chest, a 4×9 storage block.

A separate dimension with its own biome is reached by the mod and holds ruby-themed monsters to explore and fight. The mod's core drop comes from Ruby Ore, and the mod is released for NeoForge only, for 1.21.4 alone, with 1.0.0 as the latest file from 2025-08-28. It runs on client and server, so the server and every player need it, and the license is All rights reserved, so the code is not open source.

Key features

  1. Ruby tools and weapons

    Ruby Sword, Pickaxe, Multitool, Axe, Hoe and Shovel, each crafted from ruby materials and built to outlast vanilla tools.

  2. Ruby armor set

    A full armor set with helmet, chestplate, leggings and boots gives strong protection.

  3. Ruby food

    Ruby Apple and Ruby Steak are special foods with strong effects.

  4. Ruby Dimension

    A new dimension with its own biome, populated by ruby monsters that players can explore and fight.

How it compares

Full comparison

Ruby Ore Mod is NeoForge-only, built for 1.21.4 alone, with the same client and server environment and an All rights reserved license, so it covers the same version as Erze++. Ruby Blocks & Items! ships for Fabric, NeoForge and Quilt across 1.21.3 – 26.2, which reaches further in versions and loaders. Ruby Ore Kit is MIT licensed and runs on Fabric, Forge and NeoForge for 1.20.1 – 1.21.11, so it covers the widest set of loaders.
