Trial by Felfire

"(Rusted Legion, FORWARD!) Can you hear the thunder in the distance? Time to roll, Rusted Legion, ho! Cannot run, cannot hide, say goodbye to your existence. Join the army of flesh and chrome! (Here we go, here we roam, this is our world!) Will you bend your mortal knees? (Yes, you will! Yes, you will!) To Mecha-Jaraxxus, your new king? (Yes, you will! Yes, you will!) His upgraded abs are undefeated, merciless, so alpha demon, no one can defeat this team, Legion let me hear you scream! Our enemies fall in the crimson sand, they'll have no choice but to join our band, serve Mecha-Jaraxxus's evil plan, Rusted Legion sowing ashes in Outland!"

Trial by Felfire is a single-player game mode added with the Ashes of Outland expansion. The missions were released on June 17th, 2020 while the challenge mode was released on June 24th. They are also a part of celebration during the Felfire Festival.

Trial by Felfire uses a classic linear adventure format, featuring a total of 26 bosses across two sub-modes that the player can play: Story and Challenges. Trial by Felfire is completely free to play and available to everyone.

The Story mode is about following Aranna Starseeker on a journey of self-exploration, taking up arms with the Demon Hunters and teaming up with Illidan Stormrage to take on the twisted architect of the Rusted Legion itself: Mecha-Jaraxxus. Meanwhile, the Challenges mode is where the player can build a deck and take on some of Outland's biggest and baddest raid bosses.

Structure[]

For general information on adventures, see Adventure.

Trial by Felfire comprises 26 boss encounters in total.
- The adventure is split into two different modes: Story and Challenges.
- In Story mode, the player is given pre-made deck for each boss encounter, controls a special hero with their corresponding Hero Power, and gets special interactions between their hero and boss. Completing the Story will award a special card back. (see below)
- In Challenges mode, the player needs to use their own deck. Defeating all Challenges bosses will award a golden Kael'thas Sunstrider.
- Wild decks can NOT be used in Challenges mode. This makes Trial by Felfire the first Heartstone adventure to ever have this restriction.
