Grinding (Prayer)

See Ectofuntus.

When players choose to level their Prayer skill up via the Ectofuntus, one of the steps involved is grinding bones into Bonemeal. To do this, players bring pots and bones to be ground to the Bone grinder on the 2nd floor of the Ectofuntus building.

Players use the bones on the grinder, then gather the bonemeal into pots.
