Why Yi Sun-sin and Iris work together

Yi Sun-sin's Defiance Incarnate (factor 13,500) strips the target's shields and buffs. Unbreakable Fortress gives up to an 80% chance per hit to stack 1% damage reduction, up to 20 stacks. Defying the Odds adds damage against bigger troops, and Support Pillar adds garrison rage and ATK below half HP.

Iris's Withering Bloom heals lightly wounded soldiers with factor 13,000 (15,000 awakened, also cutting damage taken by 20% for 3 seconds). Herbmastery raises healing received and Infirmary medicine output, Ward of Nature gives an all-Beast Rider troop +11% HP and +13% DEF, and Script of Runes dispels debuffs while garrisoned.
