The Spell Shatter

[Sleep-Walker]

So, assuming I am using the spell shatter to sunder an object, does that use sunder rules or does the object make a saving throw??

It seems to say objects make a will save, I understand that attended objects use their wielders save, but how the hell does a willful wielder make a shield less likely to break?

What about masterwork items?

Thanks.

Think of it this way. When a person is in contact with an item, the life-force that magic manipulates bonds the wielder and the weapon. In order to destroy the weapon, the spell has to penetrate the wielder's own resistance to said spell.
