Lind was in an arena with Mills as both used various weapons created by Qi or Forged by his own hands. She relied too much on making weapons with ice that would deplete her Qi far faster compared to wielding weapons that could transform or simply various weapons.
Her Battle Aura was sharper and more deadly but its stability was incredibly lacking. She had begun to master it in everyday life at least but active use was far from her control. She injured herself if she gave into her emotions as much as her enemy.
Lind hardly ever got a scratch but he did nearly exhaust his own aura against her which was fundamentally stunning.
Gilgamesh had improved his own Battle Aura with them but he could not stand up to either of them. The Yin Nurture Physique was terrifying to be able to amplify her aura far beyond her realm.
