Clara's Transcendent Truth Eyes was finally known to be a dual physique, meaning that it was both a part of the body and the soul, her eyes acting as the gateway to the soul where her powers but also the influence stemmed from, so using Decay Laws, Evelynn was essentially eroding her eyes and soul.
From the start to the end, Evelynn didn't relax one bit, but she knew she needed even more focus when using Hex Laws.
Eventually, Evelynn's third eye shot open, shining with a blue, sealing light.
However, it didn't directly enter Clara's soul sea but surged out like threads, appearing to be completely different from the innate powers of the Three-Eyed Chromatic Hex Arachnid. This seemed to be a technique she learned.
They were tiny threads, no more than a few millimeters in thickness, and could not be seen by the common eye. They stretched out, wrapping around like a helical structure as they slithered towards Clara's forehead.
