"I used a spell that I created on you." Helix replied without hesitation.
Saul froze and stopped walking, and Helix did the same.
He couldn't believe that Helix would release the information so freely.
The guard wanted to know but recognized he would probably not get an answer.
"It's called [Desync]. I created it with the help of Grandmaster Tilo Salazar." Helix continued after turning to him.
Saul gave him a strange look.
"It throws off a person's equilibrium by disconnecting their body's brain from their body's motion." Helix explained.
"That's why you felt like your world was shaking."
Saul gruffed bitterly.
"That's one messed up spell, boy." The guard laughed.
"If you didn't disclose it to me, that spell would allow you to take out people far stronger than you."
Helix gave him a mysterious smile.
"I know. I used it on Master Tilo, and that's why he helped me make it."
Saul's eyes widened in shock.
