Hide of the Wild is an epic cloak for any kind of healer. Although its bonuses are not as high as other, BC-only healing cloaks, it has the advantage of being a craftable BoE item and so can be traded on the Auction House.

Hide of the Wild is crafted by Leatherworkers with a skill level of 300. Prior to patch 2.0.12, the Tribal Leatherworking specialty was also required.
