Hardness of Dwarven Plate Mail VS Rend Armor

[isoChron]

Well first you have an unmagical adamantine fullplate with given HP. Add to that the bonuses to hardness and HP from enhancement. So x1.3 only for the basic full plate, not the magical bonuses, too.

The armor has to be created first, before it can be enchanted with magic (ie +2 enhancement bonus)

I thought all magic items gets saves, regardless. perhaps that was just with spells.

The interpretation of this sentence can get hairy.

Not hairy at all. That is from the Magic chapter of the PHB on saving throws. Magic items never get saves from physical attacks such as striking objects and Sunder. That is why there is no save involved with the Bebelith’s rend armor ability.

Sorry, but it's actually from the Carrying and Exploration section of the SRD, under the category of Breaking and Entering. That makes the context a lot more ambiguous.

The text from the Magic Overview section reads:

Items Surviving after a Saving Throw: Unless the descriptive text for the spell specifies otherwise, all items carried or worn by a creature are assumed to survive a magical attack. If a creature rolls a natural 1 on its saving throw against the effect, however, an exposed item is harmed (if the attack can harm objects). Refer to Table: Items Affected by Magical Attacks. Determine which four objects carried or worn by the creature are most likely to be affected and roll randomly among them. The randomly determined item must make a saving throw against the attack form and take whatever damage the attack deal.
If an item is not carried or worn and is not magical, it does not get a saving throw. It simply is dealt the appropriate damage.

This really doesn't address the subject at hand.

The text from the Magic Items section (which I think you are referring to) reads:

DAMAGING MAGIC ITEMS
A magic item doesn’t need to make a saving throw unless it is unattended, it is specifically targeted by the effect, or its wielder rolls a natural 1 on his save. Magic items should always get a saving throw against spells that might deal damage to them— even against attacks from which a nonmagical item would normally get no chance to save. Magic items use the same saving throw bonus for all saves, no matter what the type (Fortitude, Reflex, or Will). A magic item’s saving throw bonus equals 2 + one-half its caster level (round down). The only exceptions to this are intelligent magic items, which make Will saves based on their own Wisdom scores.
Magic items, unless otherwise noted, take damage as nonmagical items of the same sort. A damaged magic item continues to function, but if it is destroyed, all its magical power is lost.

Which can also get hairy when a magic item is subject to a spell that normally does not allow a save.

I still maintain that damaging magic items creates more hairyness than six months of Rogaine.

Given that it's dwarven plate, and it only costs 150gp extra to make an item dwarven-craft (Races of Stone) it could have had an even greater hardness and number of HP than calculated above.

I'd highly reccomend making pretty much every piece of magical equipment you can be dwarven-craft; it's so cheap there's little reason not to.
