Baltharak Boss Guide for Trial by Felfire

The boss uses a Demon-based deck that heavily focuses on self-damaging effects like Vulgar Homunculus and Pit Lord. This, paired with the boss's All Shall Serve Hero Power which provides the boss with a huge source of healing and card draw to pair with its Demons.

The deck you are provided contains additional tech cards to force your opponent to draw cards, such as Coldlight Oracle and Dancing Swords. You will also start with Karnuk, Outcast on the field, however, it will be taken away from you early in the encounter and returned toward the end.

The boss plays a continuous stream of over-statted Demons throughout the game. You should look for a strong curve of low-cost cards to contest the board as much as possible in the early game. Dancing Swords in particar is a great keep due to its good stats and the additional card draw it gives is inconsquential as the boss will continually draw cards with its Hero Power anyway.

The boss will play a continuous stream of Demons throughout the fight and, due to the Healing from All Shall Serve, rushing will be almost impossible. Your strategy should be one of survival to exploit how fast the boss draws through its deck with its Hero Power.

Throughout the fight your only focus should be killing off any minion played by the boss. You should try to pick up the most efficient trades possible with your minions to allow you to maximise your value. When the boss's hand inevitably becomes full due to All Shall Serve, you should try to hit it with Coldlight Oracle to overdraw cards from its deck and reduce the number of minions you need to kill in the encounter. Eventually you should be able to win by killing every minion the boss plays and forcing it to take large amounts of fatigue damage from the draw effect of its Hero Power.
