12 Realms: Reprint Kit
The reprint kit concerns only the first printing of 12 Realms. If your copy does not have the Hero board double sided printed with different Talents, then you have the first printing of the game.
This kit includes the rules, Hero boards and all the cards of the basic game reprinted.
