• Cost: 0
• Effect: Can only be played if your Exude pile has 3+ cards. Deal 23 damage to all enemies.

A conditional 0-cost AoE playable only when your Exude pile has 3+ cards. Once the condition is met, it delivers 17 AoE damage (23 upgraded) at 0 cost — absurd efficiency. Exude decks accumulate Exude early, so the condition is easy to sustain. Alongside Ash Strike, it's a core finisher of Exude decks, and its 0-cost AoE offers massive total damage in multi-enemy fights. With a stable Exude loop, you can fire 17-23 AoE every turn for free — extremely strong.

Start using it mid-fight once your Exude pile passes 3 cards. Early turns (Turn 1) may not qualify, but once unlocked, it usually stays online. With War Drum (turn-start top-card Exude) in play, the condition clears quickly. Running multiple copies lets you fire multiple 0-cost AoEs per turn, overwhelming multi-enemy encounters. Combined with Ash Strike, Exude decks hold two major finishers: "0-cost AoE" and "Exude-scaling attack."

• Ash Strike: Attack dealing Exude-count x3-4 damage. Alongside End of the Contract, forms the two-finisher core of Exude decks.
• War Drum: Turn-start Exude power. Builds Exude count per turn, rapidly clearing End of the Contract's condition.
• Searing Contract: Skill that Exudes a card and draws. Accelerates the Exude cycle and keeps End of the Contract firing.
• Howl from Beyond: AoE that auto-plays from Exude each turn. A complementary AoE source in Exude decks.
• Feel No Pain / Dark Embrace: Exude synergy powers. Reinforce the entire Exude cycle and stabilize End of the Contract's uptime.
