Block Reference — Coal LLC Wiki

HP per Dollar (hp/$): HP you must break to earn $1 expected value. Lower = more efficient. Blocks within each biome are sorted by HP . Blocks marked "Visible — no drop" exist in the mine but yield nothing when broken.

Spawn Weight is a relative probability within a biome's loot pool, not a percentage. Higher weight = more common. Basic filler blocks (no ore) are omitted from this table.
