Pyrophosphite detail

Pyrophosphite is an item that is used with calcite on a mycelium pool in order to recalcify fossils into enriched bones, which are used on the eastern strange machine in the House on the Hill to gain Prayer experience.

It is dropped by monsters found on Fossil Island, and can be mined from boulders inside the Volcanic Mine. It can also be purchased for 70 points each from Petrified Pete's Ore Shop.
