With a few years under its collective belt, the Hearthstone team needed to find an edge: sharper and more striking than a corvid's beak. In The Art of Hearthstone, Volume IV: Year of the Raven, the designers, engineers, and artists of the smash-hit digital card game pour their cunning into innovative design changes, remarkable animated art, and all-new transmedia content. From the haunted lands of Gilneas in The Witchwood soaring to the laboratories of Outland in The Boomsday Project and touching down to the lively arena of Rastakhan's Rumble, the Year of the Raven has something unique for everyone. Fly alongside the Hearthstone team's creative genius (or madness?) to learn how it was done!
