アイアンクラッド

A Cost 0 skill that loses 6 HP, gains 2 Energy, draws 3 cards (5 upgraded), then Exudes. Ironclad's most devastating burst card, combining "HP loss + Energy acceleration + mass draw" in one play. Upgraded 5 draw yields 7+ Energy worth of value from 0 cost (2 Energy + 5 draws). The 6 HP cost is a serious risk, but if the resources secure a kill, the HP is effectively saved. Serves as the launchpad for explosive turns chaining Will-o-Wisp, Whirlwind, or Demon Form.

Use on turns where combos complete to deploy full force. Upgraded 0 cost yields 5 draws + 2 Energy, pulling and playing X-cost / high-cost cards like Whirlwind or Will-o-Wisp. With Blood Boil active, the 6 HP loss grants 6 Strength (12 upgraded), enabling Offering -> Whirlwind for massive damage. Since it's Exude, manage draw luck carefully to save it for the key moment. With Blood for Blood, bonus draw also triggers.

• Whirlwind: X-cost AoE. Offering's 2 Energy + full hand turns into a massive X-cost AoE.
• Will-o-Wisp: Hand-Exude damage attack. 5 draws from Offering make Will-o-Wisp explosive.
• Blood Boil: Power gaining Strength per HP loss. Offering's 6 HP cost grants 6-12 Strength instantly.
• Blood for Blood: Attack with draw on HP-loss turn. Extra draw triggers on top of Offering.
• Demon Form: Turn-start Strength. Offering's Whirlwind turn with max Demon Form stacks is devastating.

• Early Act 1: Instant pick. Provides burst to safely clear early elites.
• Late Act 1: Instant pick. Functions as core in any build.
• Act 2+: High. Burst-turn value grows as deck matures.
• Boss reward: Top. Launchpad to end boss fights in one turn.
