Large enriched bone detail.png

Large enriched bones are obtained by using large fossils (but not plant fossils) obtained from Fossil Island and depositing them into the mycelium pool. Players must add 10 pyrophosphite and 10 calcite along with the fossil to calcify it. They can then be used on the eastern Strange Machine in the House on the Hill for 1,500 Prayer experience.
