02-13-07, 03:45 AM How much does 1,350 cubic feet of adamantine weigh?
How much does adamantine cost per pound?

I've looked but haven't been able to find the answers to these questions?

This ultrahard metal adds to the quality of a weapon or suit of armor. Weapons fashioned from adamantine have a natural ability to bypass hardness when sundering weapons or attacking objects, ignoring hardness less than 20. Armor made from adamantine grants its wearer damage reduction of 1/- if it’s light armor, 2/- if it’s medium armor, and 3/- if it’s heavy armor. Adamantine is so costly that weapons and armor made from it are always of masterwork quality; the masterwork cost is included in the prices given below. Thus, adamantine weapons and ammunition have a +1 enhancement bonus on attack rolls, and the armor check penalty of adamantine armor is lessened by 1 compared to ordinary armor of its type. Items without metal parts cannot be made from adamantine. An arrow could be made of adamantine, but a quarterstaff could not.

Only weapons, armor, and shields normally made of metal can be fashioned from adamantine. Weapons, armor and shields normally made of steel that are made of adamantine have one-third more hit points than normal. Adamantine has 40 hit points per inch of thickness and hardness 20.

Here you go (http://www.d20srd.org/srd/specialMaterials.htm) Now the page gives you the price table of items... so all you have to do is take the base price of the smallest item and subtract it from the cost of the same Addy item. Their you will know how much it costs per pound.

Example: sling bullets cost 1sp for 10 but addy sling bullets would cost 60gp...

02-13-07, 09:41 AM Since adamantine doesn't mention any change in weight (unlike darkwood and mithral), I'd assume that adamantine weighs the same as steel. Search for the weight of a cubic foot of steel, and you should have your answer.

02-14-07, 04:51 AM I thought that since addy lessened the armor check penalty was lessened by 1 it would have some sort of lighten effect on the object.

02-14-07, 08:06 AM It's open to interpretation.

I'd note that it costs an extra 3000gp to make a adamantine version of a pixie's dagger or a storm giant's greatsword, which implies to me the extra cost does not come from the rarity of the material but the process and skill involved in it's making.

So raw adamantine could be worth very little or a fair bit, depending on your needs. Treat it as you would gems. (IE: You can find 50gp or 2000gp worth of it in a chunk as appropriate.)

02-14-07, 10:44 AM The Draconomicon prices Mithral and Adamantine to be 100gp a pound. Twice as valuable as gold, per pound. So its still pretty valuable (though a pound of mirthal is bigger than a pound of adamantine, which is bigger than a pound of gold). But indeed, it appears that the lion's share of the weapon's/armor's cost goes into the manufacturing of it and not so much its raw cost. With a hardness of 20, i imagine that those forges have to get awfully hot to get adamantine to come close to melting, which means more wood, hotter burning wood (or even more exotic burning materials) and bulgier muscles.

That does mean, however, that plantinum, while functionally useless as a material, is worth more than mithral and adamantine. I blame Bahamut.

MW properties.

Actually, adamantine (if anything) weights more than iron.
