How Green Stone reaches the shop

Green Stone is a Common Item. It costs 0 gold and can appear at most once per day.

Shop rules for Green Stone

  • A normal shop has five slots. Four offer Batomon. The fifth offers an eligible Item when the Item budget allows it, or a Batomon otherwise. Berroon's banked Berries and the Witch's daily Potion can keep that slot active after the usual budget is spent.
