The biggest new content of the Felfire Festival is the five-chapter Trial By Felfire Solo Adventure starting on 17 June 2020, which will follow the story of Aranna Starseeker, who teams up with Illidan Stormrage and his Demon Hunters to face off against Mecha-Jaraxxus, the mastermind of the Rusted Legion.

In a departure for Heathstone’s adventure updates, all five chapters of Trial By Felfire will go live at once. Players who completed the Solo Adventure will receive a Rusted Legion card.

On 24 June 2020, a new Challenge Mode begins, where players stand a chance of winning a Golden Kael’thas Sunstrider card. The Burndown Tavern Brawl will also return, where players play with a random deck, after a loss of which they will be given the deck of their opponent until one deck eventually wins.

On 1 July 2020, the Burndown Tavern Brawl will end and the Rumbledome will begin, where players can choose a class, one of several shiny new weapons, and enter a free for all. Besides all that, a new legendary questline will also begin on 17 June 2020:
