Whenever a “Random Item Design” is listed as the reward when looting a treasure tile, the looting player should draw a card from the random item design deck.
These cards look very similar to normal item cards, but have a blue back.
When a card is drawn, the player should find every copy of the drawn item (usually 1) with the same reference number in the deck of unavailable items and add both cards to the city’s available supply of items.
It is possible to deplete the random item design deck. In this case, additional random item design rewards have no effect.
