How does war prestige work?
When a battle is over, the winning party gains war prestige (>=0), and the losing party loses war prestige (<=0). When war prestige drops to the lowest number of your title, it won't drop any more. War prestige=A-R*B A stands for the losing party's loss B stands for the winning party's loss R stands for a weighting coefficient. The coefficient is included in calculating battle losses when one party is of much stronger than the other in a battle. Considering the battle may be easier for the stronger party and tougher for the other party, each party's prestige will be adjusted by a coefficient so that the stronger party can not take full advantage of the one-sided battle and the other party won't suffer from sheer defeat. If both parties are of the same level, the coefficient is 1. In doing so, Haypi Kingdom encourages the weaker party challenging the stronger and avoids the stronger monopolizing.
