After making her shadow essence flow around chaotically, without a proper pattern, Michelle turned toward Alexander for further instructions on how to continue.
So Alexander went on to explain the next step to her.
Apparently, vortexes had their own patterns. And they were so complex that to create them, the shadow essence needed for them had to be completely patternless. Otherwise, the vortex pattern would get twisted up and stop working.
What made things even harder was that to create a vortex, a single vortex was not enough.
There was a number of vortex patterns, and to create a working vortex, one had to mix at least three of them, without them intertwining or affecting each other.
Just a single vortex pattern required control equivalent to the Night rank. And with each new pattern added to it, the required rank had to be one higher.
