Contained in Brettspiel Adventskalender 2017 for day 2.
6 Advantage Tiles
The 6 new advantage tiles can either be shuffled in with all the existing advantage tiles, or 6 of the existing tiles can be removed from the ame and replaced with the 6 new tiles. Tip: All of the advantage tiles that earn players victory points should remain in the game.
As in the normal game, an advantage tile can only be used in a player's own turn. The two tiles with the torch symbol on them, which are used for the settlement of religious conflict, are exceptions to this: Players can use these tiles regardless of whether or not it is currently their turn.
