Bonemeal is a crafting material you make from Bones at the Grinding Stones. The game describes it as “Useful for alchemical and magical purposes.” It feeds into farming, spells, armor, weapons, and more. No enemy drops it.
Quick answer: Grind Bones at the Grinding Stones. Every 2 Bones makes 3 Bonemeal in 1 minute. Build the Grinding Stones through the Alchemist after he moves into your base.
Build the Grinding Stones to make Bonemeal
In-game, the station reads: “A simple setup for basic grinding work. Especially good for hard ingredients.” Follow the steps below to set it up.
Animals and skeletons provide Bones. You can also use the Grinding Stones to make Flour, Coal Powder, Fossilized Bone Dust, and Chitin Powder.
What Bonemeal is used for
