About the game
The Cousins' War Solo expansion enables you to play The Cousins’ War against an automated opponent, BoT. Your opponent is named after John Wenlock, 1st Baron Wenlock, a notorious turncoat, therefore called Baron of Turncoats or BoT. As a player, you pick a difficulty from Beginner, Standard, Advanced or Brutal. Then, you play the game as normal. You win the Solo game in the same way as the base game. Here is a summary of the differences between how BoT plays compared to you, the player. BoT... ◆ never uses its Action card for the Events on it. ◆ plays Actions from its Decision card. ◆ plays a number of Actions (1 to 3) by difficulty level. ◆ uses its Action card CPs for the strength of its Actions. ◆ uses your Action card to see if it has a Secondary Action... ◆ ...but uses its Decision card and a dice roll to decide what the Secondary Action is. ◆ uses printed dice on its Decision card instead of combat dice for its declaration when Active player. ◆ rolls dice to decide whether or not to challenge, and then combat dice as normal. ◆ doesn't use its CPs for nudging dice in combat (rerolls instead).
