Rubybound
by bobbyboykov
Rubybound adds a ruby-based progression path to Fabric worlds on 1.21.11, with new ore, raw and smelted ruby, and two full sets of tools.
What it does
Ruby Ore generates deep underground in the Overworld, mostly in the lower parts of the world. Breaking it drops Raw Ruby, which must be smelted in a furnace or a blast furnace before use. Ore of this kind is rare and valuable, similar to diamond, so it needs a strong pickaxe to be dug out.
Ruby tools cover melee combat with a sword and a spear for charged attacks, mining with a pickaxe, woodcutting and combat with an axe, digging with a shovel, and farming with a hoe. They take ordinary Minecraft enchantments. Later, players can create Polished Ruby, an advanced material that requires Netherite-making, and use a Ruby Upgrade Template at a smithing table to upgrade Ruby tools into Polished Ruby versions. Those inherit the abilities of the originals and deal more damage, dig faster, last longer and cannot be destroyed by fire.
Rubybound runs on the server, and players join without installing anything. It is published for Fabric only, with a single file for 1.21.11, released on 2026-07-18 under All rights reserved. The mod is not open source.
Key features
Two ruby tool sets
Ruby and Polished Ruby versions of the sword, spear, pickaxe, axe, shovel and hoe are added.
Smithing upgrade path
A Ruby Upgrade Template at a smithing table turns Ruby tools into Polished Ruby tools.
Enchantable tools
Ruby tools accept normal Minecraft enchantments, so existing enchanting setups still apply.
Creative item commands
Commands give raw ruby, ruby, polished ruby, the upgrade template and every tool, which is the only way to obtain them in creative mode.
