Mordheim House Rule - Plot Armor

A good house rule is often something that corrects a flaw without ruining the game as it is. Armor in Mordheim suffers from being overpriced for something that is routinely nullified or disregarded. If it's not 4+ strength, it's an axe, black powder weapon, or a crit roll. But changing the core rules of combat can create imbalances that might just frustrate people already very familiar with an established game.          

So Plot Amour's intent is to be a subtle way to make armor slightly more valuable, while avoiding any of the nastiness of changing the battlefield game.
