"Welcome to the Shrine of Knowledge, the place that contains many of the answers to questions that arise while playing Warhammer 40,000, Warhammer, or The Lord of The Rings Strategy Battle Game.
When in Doubt, Use the Most Important Rule!
What is the "Most Important Rule," you ask? Well, it's an idea that you will start seeing in Games Workshop rulebooks, and you should assume that it's in effect even if it's not in your particular rulebook yet. Whenever you run into a rules question during a game that you can't resolve, that's when MIR kicks in. Here's what the MIR says:
If you encounter a rules problem during one of your games and cannot find the answer in the rulebook or any other Games Workshop resource, dice off to decide on a temporary answer and get on with your game.
Okay, Now What?
After the game, take another good look through the rulebooks. The pressure of an ongoing battle can cause anyone to miss a small reference in the rules. If you still can't find your answer in the rulebooks, then that's when the Shrine of Knowledge can help.
If the answer is not here either, you can make up a "house rule" between you and your regular opponents to solve the problem.
Don't forget to visit your local Games Workshop Hobby Centre, Independent Retailer, or gaming club. Chances are that the veteran players at these locations have already encountered your particular rules question. They can either tell you where the well-hidden rule can be found or give you advice on how to resolve your dilemma.
Lastly, remember that the Hobby Specialists who staff Games Workshop's Hobby Service departments are very knowledgeable and can often help you with rules questions. Plus, if you have found a genuine grey area in the rules that has no answer, the Direct Services Hobby Specialists will notify the Games Development team. Your important feedback will help us craft new Errata documents that will hopefully resolve these rules questions. Thank you in advance for your help!"
since my GW staff, the roolzboys, and everyone i have asked in person agrees with me, not only do i have the more compelling case, but my methods have followed the GW advice for rules quandries exactly. so, according to GW, that is all i need.
even one of the data files authors agrees.
