Alright.  I might have to tweak things a bit, or give the monster a very high sunder damage to the armor; ideally, light armor should take 1-2 rounds to break, medium armor should take 2 rounds, and heavy armor should take 3-4, possibly less or more depending on how high enchanted it is and how lucky the monsters are.<br/><br/>Since armor's HP is a function of its AC value, would it make sense to have the AC drop as it takes damage?
