Runecloth

Runecloth is a cloth item drop from humanoids in the 51-60 level range. It is rarer than Mageweave Cloth, but not as rare as Felcloth. With the introduction of The Burning Crusade, this item was replaced as the most powerful normal cloth by Netherweave Cloth, which was then replaced by other cloths in subsequent expansions.
