アイアンクラッド

A Cost 3 (2 upgraded) permanent power with the incredibly strong passive "Block doesn't disappear at turn start." Normally Block resets each turn, but Barricade lets Block stack forever. Combined with Block-heavy decks, turn-by-turn defense approaches invincibility. Paired with Blood Cloak (auto 8-10 Block/turn), Block auto-stacks each turn, making mid-late game incoming damage approach zero. Also great with Body Slam (damage = current Block), turning stockpiled Block into damage. 3 cost is heavy, but upgraded 2 cost is easier.

Top priority to deploy early and begin Block accumulation. Stack Barricade with many Block sources (Defend, Shrug It Off, Blood Cloak). With Body Slam (damage = Block), you don't need to attack — just defend and Body Slam deals huge damage. With Juggernaut (damage on Block gain), every defense becomes offense. Even Impervious's (2-cost 30-40 Block + Exude) Block persists with Barricade, lasting the whole battle. Heavy 3 cost can be bypassed with Offering (0 cost + 2 Energy).

• Body Slam: Attack dealing current Block as damage. Enormous damage after Barricade stacks Block.
• Blood Cloak: Auto 8-10 Block per turn. Strongest defensive combo — stacks forever with Barricade.
• Juggernaut: Damage on Block gain. Barricade + Defend-spam stacks while hitting every turn.
• Impervious: 30-40 Block Exude skill. Block remains with Barricade for lasting massive defense.
• Shrug It Off: Block + draw. Efficient Block stacking while refilling hand.

• Early Act 1: Low. 3 cost is too heavy to deploy in early fights.
• Late Act 1: Medium. Consider taking once Block cards are online.
• Act 2+: High. With Body Slam or Blood Cloak online, Barricade completes the deck.
• Boss reward: Top. Block accumulation in long boss fights is overwhelming defense.
