That made her feel happy; she felt she had a student worthy of respect.
As for his question...
"Have you seen heavy beings moving at high speed before? Any very large beasts you've seen?" she asked.
Elliot nodded after a moment's thought.
"Yes. I've seen them. They probably have a lot of agility to do that."
She smiled.
"Maybe, but it's not so much about that. It's about strength. One of the reasons a Swordsman can't be an assassin is because they have strength + agility in their stat combination. Agility allows him to move very fast, but because he has equal or above strength, it greatly reduces agility."
"Strength reduces movement speed?" Elliot felt confused.
He had always felt it was just the opposite. The strength was exerted to increase speed.
But Anna nodded.
