Preview: Book of Heroes (Unpublished material)
The new Solo Adventure Book of Heroes will be launched on September 15, but we already got an early preview with a little trick.
About the Solo Adventure
Follow Jaina Proudmoore’s journey from scholar to mighty Mage in Hearthstone Book of Heroes, an all-new solo experience! Hearthstone Book of Heroes will bring fresh and FREE single player content over the course of the next 12 months, until the stories for all 10 core Heroes have been told. Defeating all 8 bosses in this linear adventure will reward 1 Mage Pack, containing only Mage cards from Standard!
Sadly we were able only to collect two new screenshots, but I guess better than nothing.
