These 4 special new Workshop tiles allow you to perform more powerful actions every time you visit the Market. During setup, starting with the last player and finishing with the first, each player chooses 1 of these tiles. If there are any extra tiles, they are returned to the bag. During the game, instead of placing the tile you obtain normally when claiming a Cathedral section, you can discard the one you just obtained and place your special Workshop tile. The cost is not the usual cost: instead, the cost is equal to the number of available spaces in your Workshop: if you have 6 empty spaces (i.e., you are going to place your first tile), it will cost you 6 Rubles to place it. If you have only 2 spaces free (i.e., you have already placed 4), it will cost you 2 Rubles, and so forth. Tile effects: - Obtain 1 Diamond (Its function is the same as described in the Jeweler's Guild.) - Obtain 1 Material of your choice and 1 Ruble. - Activate the Market die of your choice. - Activate any 1 of the 4 Guilds as usual. -description by the publisher's website
