アイアンクラッド

A Cost 1 AoE that deals 4 damage (7 upgraded) to all enemies plus 1 Vulnerable. Especially valuable in multi-enemy fights, applying Vulnerable to everyone at once. In decks with Vulnerable synergy (Cruel, Dissect, Brutality), it boosts follow-up damage across the board. In single-target fights, 1 Vulnerable is a low stack, but it serves as a bridge while building stacks via Bash or Tremor. Upgraded 7 damage + 1 Vulnerable is a solid AoE profile. Shines especially in Act 2+ corridor fights.

Lead off in multi-enemy fights to apply Vulnerable to all foes, then follow up with stronger attacks. With Brutality (draw on Vulnerable) in play, it draws one card per enemy hit — a huge tempo swing. Cruel amplifies AoE damage greatly. In single-target, use it as an opening to combo into Dissect (double strike on Vulnerable). With Giant (50% damage reduction from Weak enemies), pair Thunderclap's wide Vulnerable with Weak sources for a strong defensive setup.

• Brutality: Power that draws on Vulnerable application. Thunderclap's multi-apply = multi-draw.
• Cruel: Power that increases damage on Vulnerable. Amplifies Thunderclap's AoE.
• Giant: Skill for 50% damage cut from Weak enemies. Pair with Thunderclap's wide Vulnerable.
• Dissect: Double strike on Vulnerable. Combo with Thunderclap's Vulnerable for burst damage.
• Bash: Starter with 2-3 Vulnerable. Stack on top of Thunderclap for Dissect combos.
