I know there is an easy way to determine the hardness and HP of magical weapons and armor but what about items?
One of my player's has a banner of storm's eye (Magic Item Compendium), constructed of a backpack frame of wood and a banner of cloth, as this is a magic item costing 15K. How does one determine what HP and hardness and item like this has?
Should I be using the HP and hardness of a normal item of wooden construction? aka hardness 5 and hp 10 per 1inch of thickness? Or would this get additional hardness and HP as it is a magical item?
