Influence Card – Action “Deserter” - May I play a Deserter or an expansion card against my own Domains (which often would make a lot of sense during the final phase)?
No.
No.
No. The game rule does not allow this.
These “areas” are usually called “neutral zones.” You may place borders inside neutral zones, but it makes no sense and has no effect either.
No, you can also omit some.
No, that’s only possible with the action “Expand your Domain.”
One copper colored ducat must be paid. It happens to be a mistake that the rule refers to gold in this case.
Yes, you may build only one knight.
It serves the purpose of providing the game with more strategic variety: when you build a castle, having to pay for the knight obliges you to check whether there are cost-effective neighboring places for knights.
The multiple-expansion card must be used for exactly one Domain (although you may expand at two different places in a Domain, by one space each); the multiple-knight card actions may also be split up.
If it is impossible to observe the distance of six territories demanded by the rule, the distance is reduced to five territories for this particular castle. The rule demanding a distance of six territories still applies - if possible - to the other players' castles.
This rule applies to the players’ castles as well as to the neutral player’s castles used in the 2-player game.
The neutral castles in the 2-player variant serve the purpose of restricting the space for the two players.
