Rodio

Rodio is a Minetest Game mod that adds rhodium, a real-world rare metal, as an endgame material. The ore spawns only between layers -3600 and -3610 with an extremely low chance, requires a diamond or rhodium pickaxe to mine, and yields just 1 ingot per ore when smelted — making it one of the hardest materials to obtain in the game. All tools crafted from rhodium ingots have near-infinite durability and operate at near-instant speed. The sword stands out: a single hit instantly kills any entity or player regardless of their health. The hoe tills an 11×11 area in one click, automatically clearing grass and flowers before turning the soil. The full rhodium armor set, compatible with 3d_armor, grants 2500 extra hearts on top of the base health, an automatic regeneration system that restores missing HP every 5 seconds, and a 5× speed boost while the boots are equipped. Rhodium ingots can also be crafted into a decorative storage block. The mod is designed so that its incredible power is balanced entirely by the extreme rarity and difficulty of obtaining the material.
