That said, I was looking through your house rules and I was confused by the Armor DR rules you cited. Do I have a complete misunderstanding of how these rules work, or are things kind of backwards as far as protection goes? Leather armor is invulnerable to any means of getting around the DR. Chain armor is negated by piercing weapons, and Plate armor is negated by both piercing and bludgeoning weapons. What's even more confusing is that if Leather armor is magical, it almost flip-flops and becomes the worse of the armors (going from invulnerable to being vulnerable to any type of magical weapon, whereas weapons need to be both magical and piercing to get past Chain).
That just seems kind of strange to me. Could you clarify that a bit more, please? :) I've always had a hard time understanding those rules anyway, so I have little doubt I'm misunderstanding something here.
