Sunder and Magic Weapon (the spell)

[Murdock Mudeater]

Does the spell Magic Weapon (or other spells/effects that grant enhancement bonuses) increase the hardness and HP of the item targeted as per the object Hardness and HP rules?

For example, normally a light blade has 10 hardness and 2 HP. A +1 light blade has 12 hardness and 12 HP. This is based on enhancement bonuses.

Furthermore, if a weapon is subject to Magic Item, are these HP increases treated as temporary HP, or, like a barbarian, are they HP to be subtracted from the whole when the spell runs out?

I'd say that since it adds the enhancement bonus it would add the hardness and hp that comes with it and I would treat the additional hp like temp hp.

I'd say so too, it adds hardness and hp at my table.
