Strange rocks obtained by training Farming are part of the Dahmaroc statue. Two Strange rocks from each skill are required to complete the statue, which can be built once per week. Strange rocks may be stored inside a statue collection bag.
Harvesting/planting vegetables, hops, herbs, flowers, bushes, fruit trees and calquat trees; planting seeds or saplings. Raking weeds also works. The fastest way to receive these rocks is to do a standard herb/allotment run using supercompost on every patch. Wield Magic Secateurs when harvesting. If players have completed the hard Falador Tasks, it is also advisable to plant White lilies at all flower patches to protect their allotments.
