Taking him down in just a quick single hit doesn’t seem possible for Nyna yet, and she cant gauge his damage like Kaylin could to strike him when he’s just low enough to have to heal. And if his health drops to a critical level his auto-potion uses a valuable elixir to restore himself to full health. Nyna loses her grip on her new found power the more she uses it. She’ll have to master it before she can fully use it’s power- but will it last long enough?
