Hearthstone: Heroes of Warcraft fejrer Diablos 20-års jubilæum ved at introducere The Dark Wanderer til The Tavern, og på Hearthstone-hjemmesiden beskrives det således:
"The Dark Wanderer has ventured into the Tavern with mysterious purpose and presence. There's much at stake in this week's all-new Tavern Brawl — do you have the cunning and guile to unveil the Dark Wanderer's secrets?"
Besejrer du The Dark Wanderer, modtager du en cardback, der ærer Diablos jubilæum. Mon du kaster dig ud i udfordringen?
