In a game of the size and complexity of Warhammer, there are bound to be occasions where a situation is not covered by the rules, or you can’t seem to find the right page. Even if you know the rule, sometimes it is just a really close call, and players don’t agree on the precise outcome.
Nobody wants to waste valuable gaming time arguing, so be prepared to interpret a rule or come up with a suitable solution for yourselves (in a manner befitting gentlemen, of course). If you find that you and your opponent cannot agree on the application of a rule, roll a dice to see whose interpretation will apply for the remainder of the game – on a result of 1-3 player A gets to decide, on a 4-6 player B decides. Then you can get on with the fighting! Once the game is over, you can happily continue your discussion as to the finer points of the rules.
