From MC's perspective:
Duel Platform,
A hint of curiosity appeared in my eyes as this smoke reached me. I don't know what got into my mind. My heart tells me to experience the power of the dark element.
So I remained in the same position while controlling the spell. The dark smoke comes in contact with the body.
The next second, I felt pain in my nerves. I broke out in a cold sweat before channeling the gravitational force solely towards the opponent.
The Bloodline Wizard Oscar was hoping to see some changes. But he was met with even more terrible pressure.
Argh!
Which instantly made his mind go blank for a second. The bloodline power has also run its course. It reached a time limit. Because of it, the basic protection was gone from his body.
The next second, he felt even more heart-wrenching pain. Bones are cracking under the pressure. All the internal organs are squeezing, the veins are feeling the terrible burden.
