英雄の防御力

Hero's Armor is the highest-tier armor card in the game — hero-class defense that surpasses Parm Aegis. 3-cost blue card. The go-to cap for tank builds and runs targeting zero damage in boss encounters.

1. Wild (zero out the 3-cost)
2. Free to Play (hero-level defense every cycle at zero cost)
3. Duration-up (continuous maximum defense uptime)

Arcanas: Your Shield My Liege (defense → damage cut conversion), Iron Will (defense stacking). Crawlers: Ramba (peak tank archetype), Krochi. Relics: All defense-boosting relics, Gem Hammer.

Same staircase positioning as Parm Aegis — back half or final slot. Free to Play + Hero's Armor = zero-cost hero-level defense on every cycle, realistically reducing incoming damage to near zero. Pair with Your Shield My Liege for both damage mitigation and retaliatory damage conversion from high defense values.
