Originally available thru Tantrum House Season 10 Kickstarter.
During setup, replace all level 4 Sagrada Família tiles with the 4 Tiles from this promo. They work the same as the regular level 4 Sagrada Família tiles, but instead of the regular bonuses, they have certain actions depicted on them. Those actions must be resolved immediately after acquiring a Sagrada Família tile, just like the regular bonuses. In case you were to obtain one of the Promo tiles, because of someone placing Citizens on your Intersection, that player’s turn must be suspended, and you must resolve the bonus action first.
Description of all the possible bonus actions is listed below:
Perform a regular Build a Public Service action with a discount of 1 coin. You get all the benefits from that tile in the same way as if you bought that tile using an action. Remember that you are not allowed to possess more than 1 Public Service of the same type.
Perform a regular Tram action with a discount of 1 cloth.
Perform a regular Take a Modernism Project action with a discount of 1 coin.
Perform a regular Improve a Modernism Project action with a discount of 1 cloth.
