However, calling it a grayish-black tornado was a little jarring. It seemed like he needed a name.
As a straight man, Klein was very talented in naming.
Soon, Klein's eyes lit up.
"Why don't we call it Whirlwind? An instant-cast foot whirlwind. Those that require a large amount of magic are called half-step tornado of natural disasters."
This name wasn't bad. It was simple and very vivid.
Following that, Klein stood up and with a thought, a Whirlwind appeared in his hand.
In order to research the Whirlwind, Klein nearly blew up the entire catacomb.
Although it was very risky, the final result wasn't bad.
Klein could do one Whirlwind per second with the current one.
Although the damage was far worse than a half-step calamity, it could still reach the level of a Golden Spiral Shuriken.
With this in mind, Klein directly launched his attack.
