Full Plate Armor from Ancient White Dragon

[joep]

So the party defeated an Ancient White Dragon. But not after I killed their Barbarian.
Dragon killed the Barbarian and was going to get the Ranger next, until he rolled 2 natural 20's on his attack.
He used Quarry, and cast instant enemy so the critical's were instantly confirmed.

After said and done, the Ranger killed the Dragon, the Cleric did Breath of Life so Barbarian was saved.

Now, Barbarian wants to take his +3 Full Plate, and make +4 Full PLate using the scales from the Dragon.

I've got no problem with this and in Hero Lab I edited his current armor to be +4, and changed material to Dragonhide

Would the Dragon Scales give Cold Resistance, and if so, how much?

Dragonhide as presented by RAW. It's a pretty bleh material really, but you are the DM so you can make it better.

[Bandw2]

you can do what ever you want with it, i know there's some optional rules out there somewhere for using strange materials for magic items instead of straight dosh, but it almost entirely says the GM should just do what ever he thinks is appropriate in this regard.

Dragonhide as a material is primarily used for letting druids wear bigger "natural" armor so they can keep their druid abilities. But of course, you can do whatever you see fit in improving his armor.

I strongly advice going against the rules and ruling that the armor give cold resistance for free, they killed and ancient dragon for Asmodeus sake.

[Blackvial]

If I remember correctly dragonhide gets the frost resistance once it is enchanted

[Brf]

Dragonhide is automatically immune to whatever energy type that dragon was immune to. If it is enchanted to protect it's wearer from that energy, it is a 25% cost reduction to add that energy immunity. There is no automatic resistance for the wearer.

[Rogar Stonebow]

Actually using dragonhide gives a discount on enchanting it for cold resistance.

I'll just simplify things..

Dragonhide wrote:

Armorsmiths can work with the hides of dragons to produce armor or shields of masterwork quality. One dragon produces enough hide for a single suit of masterwork hide armor for a creature one size category smaller than the dragon. By selecting only choice scales and bits of hide, an armorsmith can produce one suit of masterwork banded mail for a creature two sizes smaller, one suit of masterwork half-plate for a creature three sizes smaller, or one masterwork breastplate or suit of full plate for a creature four sizes smaller. In each case, enough hide is available to produce a light or heavy masterwork shield in addition to the armor, provided that the dragon is Large or larger. If the dragonhide comes from a dragon that had immunity to an energy type, the armor is also immune to that energy type, although this does not confer any protection to the wearer. If the armor or shield is later given the ability to protect the wearer against that energy type, the cost to add such protection is reduced by 25%.

Because dragonhide armor isn't made of metal, druids can wear it without penalty.

Dragonhide armor costs twice as much as masterwork armor of that type, but it takes no longer to make than ordinary armor of that type (double all Craft results).

Dragonhide has 10 hit points per inch of thickness and hardness 10. The hide of a dragon is typically between 1/2 inch and 1 inch thick.
