In my game we are having arguments about damaging worn items both mundane and magical. My contention is that if a character can be physically damaged so can items he is wearing, using or carrying can be as well. So if a dragons breath or an acid flask strikes a character exposed items should be damaged along with the character. This would be subject to saving throws (attended and if the item is magical or not) and also subject to the order of precedence eg shield first. My players are saying that nothing can be damaged unless they roll a 1 on saving throws or the item is specifically targeted. It doesnt make sense that all items and armor should be immune to the ravages of combat, magic and the elements. I feel if the player would take the damage the gear should be vulnerable as well. So a player that buys a suit of chain or a shield would never have to repair them even if bitten bashed or roasted by monsters.
