悪魔化・限界突破・筋力の碑文などの強力なパワーカードを序盤から連打して、筋力を急速に積み上げる爆発的ビルド。

• 悪魔化: 毎ターン筋力+2（強化後3）の無限スケールパワー。絶対に取る。
• 限界突破: 現在の筋力を2倍にするスキル。悪魔化と組み合わせて爆発的成長。
• 旋風刃: Xコスト全体攻撃。筋力スタック後に使うと圧倒的ダメージ。
• 衝拳: 筋力×2のダメージを与えるアタック。筋力ビルドの主力ダメージ源。
• イフリート: 筋力を獲得するパワー。悪魔化との重ね合わせで高速スケール。
• 供物: パワーを多く積むためのエナジー・ドロー源。

1. Act1からパワーカードを積極的にピックし筋力スケールの基盤を作る
2. Act2で悪魔化・限界突破が揃ったら毎ターン筋力が増え続ける
3. 旋風刃・衝拳でスケールした筋力を攻撃力に転化

• パワーカードを大量に積むとデッキが重くなりがち。ドロー手段とのバランスに注意
• 悪魔化は毎ターンHP1消費。HPを気にしながら運用すること :::

Ironclad Primal Power Build

The Primal Power Build stacks Strength as fast as possible through Demon Form, Inflame, and Limit Break, then converts that Strength into lethal damage with multiplier attacks like Heavy Blade and Whirlwind. Demon Form's +2 Strength per turn compounds over a fight; Limit Break doubles whatever you've built midway through. The early game demands enough Block to survive while ramping; once Strength clears 15 the board flips entirely in your favor.

• Demon Form: Power costing 3. Gain 2 Strength at the start of each turn (3 upgraded). The non-negotiable engine — build everything around playing this as fast as possible.
• Limit Break: Skill costing 1, Exhaust. Double your current Strength. At 12 Strength this turns it to 24 instantly; timing it correctly wins fights outright.
• Inflame: Power costing 1. Immediately gain 2 Strength. Multiple copies stack; two Inflames before Demon Form's first tick means you start at 4 Strength.
• Heavy Blade: Attack costing 2. Deals 14 + (5× Strength) damage (7× upgraded). At 20 Strength this single card hits for 114 damage.
• Whirlwind: Attack costing X. Hits all enemies 5 times × X energy (8× upgraded). Each hit scales with Strength — ideal for multi-enemy rooms and Vulnerable targets.
• Upper Cut: Attack costing 2. Deal damage and apply Vulnerable. Use before Heavy Blade or Whirlwind to boost their damage by 50%.
• Offering: Skill costing 0, Exhaust. Lose 6 HP, gain 2 Energy + draw 3. Lets you play Demon Form on turn 1 alongside other cards.

• Akabeko: Your first attack each combat deals 8 extra damage. A substantial bonus on the already-inflated first Whirlwind.
• Paper Krane: Applying Weak increases your Strength by 2. Pairs with Upper Cut to make each Vulnerable application also accelerate Strength scaling.
• Champion Belt: Applying Vulnerable also applies Weak. Turns Upper Cut into a trigger for both Vulnerable and Paper Krane's Strength gain simultaneously.

1. Use Offering on turn 1 if available to afford Demon Form plus another card in the same turn — losing 6 HP is well worth the tempo.
2. Play Demon Form the moment you draw it; each turn delayed permanently costs Strength.
3. Stack Inflame before or alongside Demon Form so Limit Break doubles a larger base.
4. Time Limit Break after 3-4 Demon Form ticks (roughly 6-8 Strength from ticks alone) for the strongest doubling effect.
5. Apply Vulnerable via Upper Cut before unleashing Heavy Blade or a large Whirlwind for 50% bonus damage.

• Demon Form: Must take — this is the engine, not optional.
• Limit Break: Must take — a single use can win a fight.
• Inflame: High — every copy stacks; more copies = higher Limit Break payoff.
• Heavy Blade: High — the single highest-ceiling damage card with Strength.
• Whirlwind: High — excellent vs. multi-enemy rooms; scales better than most attacks.
• Upper Cut: High if Vulnerable sources are scarce; lower once other Vulnerable cards are in the deck.
• Offering / draw cards: High — the build relies on playing 3-cost Powers quickly.

• Demon Form costs 3 Energy on what may be a 3-Energy turn. Don't be afraid to spend a "do nothing" turn playing it — the long-term Strength gain is always worth it.
• Upgraded Demon Form gives 3 Strength per turn. Make it an upgrade priority alongside Limit Break.
• Heavy Blade's bonus scales by 5× (or 7× upgraded) Strength per hit; at 20 Strength the total damage is 14 + 140 = 154. Upgrading it to 7× changes the equation meaningfully.
• If you don't find Limit Break, Inflame + Demon Form still scales over long fights — focus on surviving into turns 6-8 to let Demon Form do the work.
• Multi-hit attacks (Twin Strike, Cleave) benefit more per Strength point than single hits. Prefer them in drafts when available. :::
