Start with 2 , 1 , and 3 workers (strengths 2, 1, 1). Whenever you retrieve, collect one additional income. You may not collect twice on the same unless you have an ability that specifies otherwise. Note that tiles and cards that use the word “retrieve” trigger this ability, whereas those that specify only “collect income” do not.
