Tired of your wardrobe’s over-reliance on black? If you’re a warlock looking to step out of the shadows and into something with a lighter rustic flare, look no further. Sure, not even the most beautiful tailoring will be able to make your guildmates forget about your pacts with the darkest of demons, but when you’re wearing      Stonecloth Robe you’ll be the talk of the druids — and this time not because of your terrifying command of the forces of darkness!

And if you’re worried that a granola-eating, walk with the Earthmother set like this one “just isn’t you,” never fear: the skulls on your shoulders will make you feel right at home.
