Liam had two ideas for both darkness and chaos.
For the former, he wanted it to synergize with his Shadow.
Something that could remove the illumination of a small area in order for his Shadow to work at full strength.
A smoke bomb, to be exact.
Something like that required gaseous darkness, held together by a solid, darkness-made container.
It had to be big enough to envelop Liam's fighting range, and last at least 30 seconds.
And for the latter, he would just build upon the Controlling Chaos spell.
Harnessing the power of his chaos required Liam to delay its destructive power.
Otherwise, it would just be a one-dimensional energy that could only destroy.
There had to be more to it than that.
Obviously, Liam didn't have any problem with the explosiveness of his chaos.
But if he could decide when it exploded… that would be massively different.
