• Cost: 0
• Effect: Gain 2 Energy. Draw 2 cards. Exhaust.

An Exhaust Skill that grants 1-2 Energy and 2 draws at cost 0. Single-use, but that single use creates enormous advantage. Since it boosts both Energy and draw at once, it's useful in any situation — especially clutch moments (want to play a big card but short on Energy, or want more draw). Being Exhaust, it thins the deck, also pairing well with Grand Finale decks. Upgrading to +2 Energy enables even bigger reversals. One of the best Exhaust Skills in the game.

• Cost 0 means you can play it with any hand, but value is maximized in Energy-short or key-draw situations.
• With Corrosive Wave, Adrenaline's 2 draws trigger Poison twice.
• As an Exhaust, it thins the deck; in Grand Finale decks, actively use Exhaust cards to thin faster.
• Combined with Bullet Time, gain Energy with Adrenaline first, then Bullet Time lets you play many cards.
• Upgraded gains 2 Energy, enabling an extra 2-cost card — great for sealing the game late.

• Corrosive Wave: AoE Poison each draw this turn. Adrenaline's 2 draws trigger Poison twice.
• Grand Finale: The Exhaust thinning concept aligns. Speeds up emptying the draw pile.
• Bullet Time: Play your hand at cost 0. Gain Energy with Adrenaline first, then Bullet Time for max plays.
• Afterimage: Gain 1 Block each play. Even Exhaust Adrenaline triggers it.

• Act 1 early: Top priority. Strongest Exhaust Skill, useful in any deck. Grab on sight.
• Act 1 late: Top priority. Universal pick regardless of build direction.
• Act 2+: High priority. One copy is usually enough, but a second can be justified.
• Boss reward: Top priority. Energy + draw burst decides boss fight clutch turns.
