Is it actually possible to go a whole extended campaign without deviating from WBL any? Cuz I've never seen it happen.

Anyways, Sunder works fine; this is why spells like Mending and Repair exist, is to fix broken objects. Unless Sunder is supposed to remove all magic from an item upon breaking? Easy fix there is to make a new spell that repairs the enchantment as well. Problem solved, and it only took one spell slot. I honestly don't see why Sunder is so disliked, other than the fact that it's an inconvenience. I mean, disarm is just as annoying; a Rogue can steal a Cleric's holy symbol just as easily as a trained Fighter can smash it.
