"The architect keeps changing his mind as to the design of the new Keythedral. As a result, the resources that are now required from the workers have changed!" These building tiles should only be used once you are familiar with the standard game. The reason is that they require players to obtain a more unusual mix of resources and are likely to distort the end of the game with unpredictable results. The 8 new tiles are: 6-Brown 6-Blue 6-Green 6-Red 6-Black 1-Gold + 1-Law 1-Purple + 2-Laws 2-White + 1-Law Expands: Keythedral, Richard Breese's fourth game in the key series.
