Osmium is the densest natural metal in the mod - built for extreme durability and knockback resistance rather than speed.

Generation: Overworld, in stone and deepslate. It generates from Y -32 to Y 0, in clusters of 4, with 4 veins per chunk, and never disappears when exposed to air.

Drops: 1 Raw Osmium per block, boosted by Fortune, or the ore block itself when mined with Silk Touch.

Tool stats: 1900 durability, 6.0 mining speed (the slowest of the upper tiers), +8.5 attack damage bonus, enchantability 22. It is not correct for iron-tier-only blocks.

Special ability: The complete four-piece Osmium armor set pulls the wearer down through water for fast sinking and lets them walk normally on the seafloor instead of floating - wearing only part of the set does not trigger this effect.
