Rules in wiki were changed to:
In the tactics phase the player compares his/her domains with the opponent domains in order to see if he/she has won any of the three possible tactical victories. To get to know the strength of his/her specific domain, the player sums up the gold cost of all unmarked creatures in it.
Example: The player has 3 cards in the domain called ''Soul''. The first creature card has a gold cost value of 3, the second creatures gold cost is 2, and the third creatures gold cost is 5. Hence, the players domain point in Mind is 10 (3 + 2 + 5 = 10)
Added new region rule
During the discard phase, in wiki:
The player may discard his/her active region. If that happens, the next one is revealed and turned face up, and becomes the new active region. Discarding the last regions counts as a loss of the game.
