Small enriched bones are obtained by using small fossils obtained from Fossil Island and depositing them into the mycelium pool. Players must add pyrophosphite and calcite along with the fossil to calcify it.
They are then used on the eastern strange machine inside the House on the Hill for 500 Prayer experience.
Trivia[]
- Upon release, the small enriched bone only granted players 100 Prayer experience. This was increased to 500 in an update on 18 January 2018.
