Conflagration

Conflagration is a 2-cost Rare Attack card for the Ironclad that deals 12 damage to ALL enemies and Exhausts every other card in your hand. This combines area-of-effect damage with massive Exhaust triggers, but leaves you with an empty hand afterward.

Conflagration is the AoE counterpart to Fiend Fire's single-target burst. Dark Embrace draws a card for each Exhausted card, immediately refilling your hand after the Conflagration. Feel No Pain generates Block for each Exhaust, making Conflagration both offensive and defensive. Follow up with Ashen Strike for massive damage from the inflated Exhaust pile. Evil Eye and Forgotten Ritual also trigger off the mass Exhaust for Block and energy respectively.

Conflagration is the Ironclad's best AoE option in Exhaust decks. Pick it when facing multi-enemy fights alongside Dark Embrace to recover from the hand loss. Without Dark Embrace, playing Conflagration leaves you helpless for the remainder of the turn. Against Test Subject #C10 and fights with multiple enemies, the AoE damage plus Exhaust synergy is devastating. Time it carefully to maximize the cards Exhausted from your hand.
