Figuring Hitpoints for items.

[Joker]

Is there a table anywhere that shows the Hitpoints of items like bracers, helms, iron-shod boots etc?

Also, how do you calculate the hitpoints of the same items but made out of different materials? I.e. adamantine, mithril, obdurium etc.

What I'm looking for in particular is how many hitpoints an adamantine helm would have.

Anyone?

I tried to figure out some hitpoints but I left out helmets (bad me). Made a small excel sheet.
Bracers of Adamantine I would give 4 hitpoints (hardness 20 of course).
Same for a circlet. But that is just derived from the HP/inch table. I included many other materials, but where do I find obdurium ?
I used the materials from Arms and Equipment Guide, DMG and Magic of Faerûn.

Obdurium is material from the Stronghold Builders Guide. Basically 1.5 times as strong as adamantine, i.e. hardness 30, 60 hp's per inch of thickness.

I thought about deriving item hitpoints from hp's per inch data. Oh well, how thick were helmets in real life?

 

[isoChron]

Hmm, 5 mm ~ 1/5 inch seems a good thickness for helmet material.

Most items won't survive long against sonic or acid attacks. (Or does hardness suddenly apply to these energy forms as well?)

No, unfortunately they won't last . I should know, I just lost 163k of items because our wizard didn't take into account that the items on my corpse were unattented . One sonic fireball took care of almost everything.

Funny how I was more ticked about my items than I was about my character's death .

I think there is something wrong with that.

Well in a campaign I ran, the barbarian died through massive damage (!) she rolled a 1 on her save. Her items all got destroyed by simple manes, small demons that explode in a little cloud of acid. 2 or 3 of them where sufficient to ruin all her items. She didn't come back from the dead . We lost a paladin and her items in the same fight along with a cleric and his items, too. There was a circle of vrocks practicing the "dance of ruin" with success. This destroyed anything that remained, along with a dropped bow and a very expensive thrown dagger.
Area spells can be very very nasty.
Only very few items have a chance to survive: heavy armor and weapons with high bonuses.
