Kairos hadn't fully charged up the darkness spell as he would've liked as he had only used a quarter of his mana, but he didn't really have much of a choice anymore when he saw the spiky ball monster rushing towards him.
After opening his mouth, he released a ball of dark mist, with a wide jagged smile on top of it. A line of long tendrils trailed behind it, making it look somewhat like a squid. Although it didn't travel particularly fast, the monster had no intention of shifting its direction, instead opting to plow right through it.
And it did just that, slamming right through.
However, the spell still retained itself, wrapping the many tendrils it had around the spikes and constricting them, preventing the monster from moving as it liked. In the end, it just remained there, shaking in its struggle but unable to do anything more. The small snakes that Nyoka had continued biting into its skin, making even more wounds that continued to bleed.
*It was in fact, not fine*
