Miran's Elements

Ruby ore generates underground in a band between Y levels -50 and -30, and a Netherite pickaxe is the only tool that can break it. Cobalt is not found in the world; a player makes it by crafting a Netherite ingot together with a Ruby ingot. Cobalt is then used to make tools and armor that the mod describes as much stronger than the diamond and Netherite gear already in the game.

Uranium is the hardest material. It spawns as a meteorite in the End dimension between Y levels 30 and 70, and only a Cobalt pickaxe breaks it. Usable Uranium requires a longer route: raw uranium is processed at a Chemistry Table with Cleaning Lotion, then smelted in a furnace. Only after these steps does the player obtain the uranium ore that the new equipment needs.

The equipment is built for an RPG or hard-mode style of play, where the materials are difficult to obtain and the items are hard to ruin. The author notes that the mod may feel overpowered for some players and suggests pairing it with a hard or challenging mod to keep overall balance. Miran's Elements runs on client and server, so the server and every player need it. It requires Forge for 1.20.1 and is released under the Apache License 2.0; it is not open source.
