Dragon-hide and “Other Creature-hide” Armors
The cost (value) of creature hide armor is equal to the adjusted natural armor bonus multiplied by 400gp, then add the Armor’s (normal) cost in gold pieces multiplied by 2, and then multiply the total by 20; So a suit of “+5 Natural AC Great Wyrm Red Dragon-hide masterwork full-plate” would be worth 100,000gp.
+1 Natural AC is added to the Armor Bonus of a shield or suit of armor for every +7 (round down) natural armor of the original creature.
This bonus to the armor reflects the natural toughness of the hide of the creature it was made from this is not an enchantment or a natural armor bonus to the creature using it so it “stacks” with a spell’s, item’s, or creature’s natural armor bonus.
So armor made of Ankheg hide would provide an additional +1 natural armor to a suit of armor made from it (an Ankheg has +9 natural/7=1.3 round down is +1)
A creature produces enough hide for a single suit of masterwork hide armor for a creature up to one size smaller than the creature.
By selecting only choice bits of hide, an armor smith can produce one suit of masterwork banded-mail for a creature up to two sizes smaller, or one suit of masterwork half-plate for a creature up to three times smaller, or one suit of masterwork breastplate or suit of masterwork full plate for a creature four times smaller.
A creature of large size or larger can also produce enough hide for a single masterwork buckler, masterwork large shield or masterwork small shield along with the armor (treat shields as medium sized hide armor for the purpose of making it out of “blended” hides).
A masterwork tower shield can be made from the entire hide of a large size or larger creature.
If a creature is to small to make armor with its single hide, it can be added to the hide of other creatures to make a single suit of “blended” armor, when making “blended” armor hides from two creatures of the same size as the size of the armor are needed to make a single suit of masterwork hide armor, four for a suit of masterwork banned-mail, eight for a suit of masterwork half-plate, sixteen for a masterwork breastplate or masterwork full plate.
Twice as many hides are needed to make a suit of armor for each size smaller the base creature is from the size of the armor being made.
So if your were making a suit of armor for a medium size human out of tiny creature hides you’d need four times the amount of hide you would use then if it was made out of medium sized creatures, so a suit of medium sized masterwork full plate would take sixty four tiny creature hides to make.
Blended armor can be made out of creatures of different sizes.
When making “blended” armor get the average Natural Armor of the creatures used to find the armor bonus.
So, if your using 3 creatures add the 3 creatures Natural Armor Bonus and divide by 3 (round down), then divide the “average” natural armor bonus by 7 to find the natural armor bonus to the armor being made.
