217 Chapter 217 – Lightning Sphere

"Let's see," Gravis said, readying his saber again. "Let's try with something small, like 5% of my Spirit."

Gravis summoned a mixture with only five percent of his Spirit, yet something unforeseen happened.

POP!

The mixture wasn't able to stabilize and scattered into the surroundings. This hadn't happened before, so Gravis was confused for a second, but he quickly noticed the difference between this time and last time. "The last couple of times, I always used 10% of my Spirit. I guess I need a minimum amount of Spirit to make the fusion work. Funny, the manual hadn't mentioned that," Gravis muttered.

Then, Gravis summoned another mixture with 10% of his Spirit. Like the first three times, it remained stable. "So, it really requires a minimum of Spirit to stabilize," Gravis muttered while scratching his chin in thought. "I wonder how lightning interacts with it."

Then, Gravis started slowly infusing the mixture with lightning.

WHOOOM!
