Contained in Brettspiel Adventskalender 2015 for Day 20.
5 Cloister hex tiles.
Each round, place one cloister (in place of a black-backed tile) onto the central black depot. All other rules regarding the black depot remain the same.
As with other black-backed tiles, a cloister can be bought from the central black depot for 2 Silverlings, and is then placed onto an empty storage space in the bottom left-hand corner of the player’s board.
This owned cloister can be placed onto an empty space in the player’s estate that is adjacent to at least one previously placed tile and that matches the number on the player’s die.
The cloister does not have a function after placement, but simply helps complete a region.
Note: The size of a region increases by 1 for each cloister within it. However, a region containing one or more cloisters can never be greater than 8!
Example: A 4-space region with 2 cloisters on it is considered a 6-space region, earning 21 victory points instead of only 10.
