"What do you mean?"
Diana had a light frown across her face for the first time.
Her eyebrows raised, with her mouth forming a slight pout. Maybe she didn't know what kind of expression she currently had, but it surely was a sight to see.
"Mana is something that is an integral part of our world. Not using it would be a foolish thing to do. But in the process of using mana, you have become too reliant on it and have neglected the basic physical endurance that your body needs."
I moved towards Diana, standing just a few feet away.
"You expend mana in each attack, which might indeed give you more physical boosts in the short term, but if the battle becomes long-drawn, then your defeat would be the obvious result."
Diana, for the entire time, had her eyes looking downward.
The silence stretched between us before Diana looked up to stare into my eyes.
"You had always been good at giving advice to others."
