Determining hardness and HP of magical items

Question

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?

Answer 1

Use the normal hardness and HP for wood.

From the main 3.5 FAQ:

Magic items that have no enhancement bonuses—which is almost everything except weapons, shields, and armor—have no extra hardness or hit points. For example, a paper scroll has a hardness of 0 and 1 hit point, no matter how many spells it contains.

Putting enhancements (ex. a +1 sword) onto armor or weapons is what increases hardness and HP. A magic item that doesn't have that enhancement has no special protection from damage.
