I don't want to go into much details about attrition rules, they are my secret recipe
max dice count is 8 for all types of games (if you see more, it is a bug, let me know pls what kind of game, what happened before and if it is only visual bug or function as well. e.g. when you attack this region, does it feel like it has more dice).
I am not sure I will get around to making detailed info about everything, I would rather fix bugs and implement new features
