Actually, a problem arose during the game. Zwei attacked me with skeletons, and I was running away as a gargoyle; I was unreachable, and according to the rules, he should have retreated, but the thing is, he didn't know that; he thought that since I refused to fight fairly, I should retreat. Well, it happens; it's a standard situation, not the easiest rule.

The problem is that I searched for a long time for the rules in English and couldn't find it. Does it even exist?
