Strange rock (Thieving)

Strange rocks obtained by training Thieving are part of the Dahmaroc statue. 2 are required each to complete the statue each week. Strange rocks may be stored inside a statue collection bag.

Obtaining
Attempting to pickpocket an NPC that a player has the Thieving level for (even if unsuccessful); stealing from stalls; stealing from chests. Master farmers are recommended for lower level thieves due to their left-click pickpocket option.

For higher level thieves, thieving elf workers is best due to the lack of attention needed. Knocking out and pickpocketing Menaphite Thugs works, but not Monkey knife fighters.

The Pyramid Plunder minigame will not yield strange rocks.
