This is a translation of the effect Bilescourge Bombers, from Warlock in World of Warcraft over to Hearthstone. I used Unity, Photoshop, Blender, Substance Painter, and Substance Designer. I had a lot of fun trying to animate the Bombers in Photoshop and layering them in.
Additional tools I used were Hearthstone, World of Warcraft, and WoWHead.
