Corruption was the negative power that changed a being, distorting their being and changing them from what they originally are.
This power, while common within the monsters that appear in the tower, was a different thing when it was present as a stat.
Those who possessed the Corruption stat could degrade a being from what they are, meaning those who possessed the stat could make good people fall from grace and make bad people worse.
The demons were entities who usually possessed Corruption, and those who possessed Darkness as well could manipulate the power of darkness, the element opposite of Light.
The two powers that this demoness possessed was something special, something that made her potential higher than that of the same kind.
She also had a class but it wasn't proving to be much effective due to the restrictions of the tower.
She was frustrated that she could not use much of her powers, but when KiRA called her useless, something snapped inside her.
