by PhysixAA

Cobalt Changes is a NeoForge mod by PhysixAA that adds two ores, Cobalt and Vanadium, which spawn on upper island levels in the Cobalt Clouds modpack.

NeoForgeClient and serverMIT License1.21.1

What it does

The mod adds two new ores, Cobalt and Vanadium, that generate at the upper island levels of the world. Each ore comes with its own material and the crafting components made from it, so the ores feed into recipes rather than standing alone. The recipes are added through KubeJS scripts, in the same way that similar mods add their features.

Cobalt Changes was designed for the Cobalt Clouds modpack, and its recipes are built with that pack in mind. The author recommends using it outside the pack only with care, because the inherent recipes may not fit another progression. It runs on client and server, so a server and every player need it. The mod is published for NeoForge only, for Minecraft 1.21.1, under the MIT License, and it is not open source.
