Demon Form

Demon Form is a 3-Energy Ironclad rare Power that grants 2 permanent Strength at the start of every subsequent turn (3 Strength upgraded). The compounding Strength is what makes it exceptional: after 3 turns, Demon Form has contributed 6-9 Strength. After 5 turns, 10-15. Every attack in your deck scales with this accumulating bonus, turning even mediocre attacks into devastating ones as the fight progresses.

The 3-Energy cost means the turn you play Demon Form is largely spent on setup. Fights need to last long enough for the Strength to pay off — it's most powerful against bosses and multi-phase encounters. Upgraded at 3 Strength per turn, the scaling is faster. Paired with Limit Break to double accumulated Strength, or Headbutt to guarantee Limit Break next draw, Demon Form is the Ironclad's most powerful long-term scaling engine.
