Kathryn Emberwind can empower her allied Elves with her mighty Hero's Bane, which makes a large swarm of even the weakest Elves a deadly threat. This effect is quite powerful with allies in possession of Fire Synergia, which amplifies the damage drastically, or Freyja, who will buff all allied Elves every turn. Kathryn Emberwind works quite well with Tariel the Phalanx, who will summon an Elfin with both her ordinary attack and the Hero's Bane. In addition, the Elfins will benefit from the Hero's Bane Aura as well.
On Awakening, Kathryn Emberwind gains increased health and a more potent Hero's Bane Aura, allowing her to crush the enemy twice as fast.
Hero's Bane 1: Elves
Hero's Bane 2: Elves
