Upgraded

• Cost: 1
• Effect: Deal 6 damage twice. Exude a random Attack in hand; add its damage to this.

A Cost 1 Attack dealing 4 damage x2 (6 x2 upgraded) while randomly Exuding an Attack in hand and adding that card's damage to Flurry. Higher-damage Exudes mean bigger bonuses — Exuding Skull Bash (32 damage) adds 32 to Flurry, totaling 40+ damage. It also triggers Exude synergies. The random Exude risks sacrificing strong cards, but upgraded's 12 base damage (6x2) plus the bonus delivers very high damage.

Safer when your hand holds Attacks that are fine to lose (starter Strikes, cards with copies). Using it when no essential cards are in hand minimizes variance. With Feel No Pain (Block on Exude) or Dark Embrace (draw on Exude) in play, the Exude also triggers their effects for high efficiency. Combined with Will-o-Wisp or Second Wind (hand-wide Exude), intentionally filling hand before Flurry reliably produces high damage.

• Feel No Pain: Power granting Block on Exude. Flurry's Exude automatically adds Block.
• Ash Strike: Exude-count scaling Attack. Flurry's Exude raises Ash Strike's count.
• Dark Embrace: Power drawing on Exude. Flurry's Exude triggers a draw, refilling hand.
• Skull Bash: 3-cost 32-42 damage Attack. Exuding it via Flurry yields a massive bonus (hard to intentionally target though).
• Inflame / Demon Form: Strength buff powers. Flurry's 2 hits ride Strength, boosting base damage.
