Farming
A good place to farm for Plague Idols is from the Am Fah along the corridor on the East side of Wajjun Bazaar (marked in green on the map). Leave from the The Marketplace or Nahpui Quarter.

Be certain that Seek out Brother Tosai is not active in your Quest log, or none of the Am Fah you encounter will be aggressive towards you.

Another good place to farm is during the quest Deactivating P.O.X. because there is hordes of Am Fah.
