Against Demi Gods
Before advancing to the Driekta stage, and before creating the prototype of the UTC, Jason first wanted to figure out what kinds of runic constellations he wanted to inscribe into the God's Halo.
This was quite important because runic constellations were compounds made up of millions of inter-connected runes that replicated specific abilities and effects.
It was even possible for him to replicate the materialization of the Dragonhead, spitting out highly potent flames.
And this technique was something that could be considered Solaris' signature attack.
It loved to use the shape of the golden-eyed black dragon, which was why it used this attack over and over again.
In the end, Jason knew that it was the Origin flames' strongest ability.
Because of that, he considered inscribing it on his God's Halo to replicate it at will.
However, that was not necessary because he had Solaris by his side.
