Might Be: Tool Expansion is a mod made for Minecraft Forge 1.20.1, it currently adds 3 New side-grades to tools and armor sets, Crystallized Lightning, Iridanium, and Molten. that can be obtained via the Smithing Table, the resources to make these new sets are very rare, and vary on location depending on the set.
I recommend using a recipe browser mod like JEI or REI.
This mod is inspired by Terraria.
