Nephis had grown vastly more powerful after attaining Supremacy. However, there was nuance to that newfound power — not all of it came easily, and not all of it could be used freely in any situation.
Take her Supreme Aspect Ability, for example. Sunny had gained the Ability to summon the shades that rested within him into existence, thus becoming a walking army... an army of indestructible shadows that grew with each living being he slayed, no less, which made him a truly terrifying existence.
Nephis had gained an immensely powerful Ability, as well. However, her Supreme Ability did nothing to empower Nephis herself — instead, it empowered the subjects of her Domain, allowing her to heal and empower them with her flames from a distance.
Which was why it was truly unfortunate that she had to face the Cursed Demon alone... not that there were many people out there who could have assisted her in a battle against a Cursed abomination.
