Ashen Scales is a set of enchanted splint mail +2 made of wyvern scales. Like normal splint mail, it provides the same protection modifier and it requires 8 Strength to wear this, but the Armor Class is improved by two points. With a weight of 18 lbs., it's 22 lbs. lighter than splint mail. Ashen Scales appear in Baldur's Gate II: Shadows of Amn, it's obtained during the assault on Bodhi's lair. It can be found in the lowest room of the lair.
Instead of metal strips, this armor uses wyvern scales bound to a chain backing by means of a magical fire. The resulting armor is ash grey in color and more flexible than standard splint mail. A ranger, Usher Skacan. made this armor after slaying several wyverns that were killing all the deer and elk in his forest.
