The Tier 1 and Tier 2 versions of every type of material are always available and are in infinite numbers. To rapidly buy an item, you can push the triangle button repeatedly. Two other random materials (the materials may or may not be identical) varying from Tier 3 to Tier 5 will be available for purchase. Each of these materials will take one slot (even if they are the same) and can only be bought once (and not multiple times unlike Tier 1 and Tier 2 materials) from each slot listing an item. In addition, randomly chosen magic-imbued equipment will be available for purchase priced according to the equipment type (e.g., Chariot, Bow) and the imbued magic (such as Flame or Strength). The items seem to be chosen at random.
