How should I evolve and combine them?
The Star Patterns that were already engraved were out of consideration for Thunder Star Skills, so only the Fire Series Star Patterns and Divine Soul Star Patterns were options.
If possible to strengthen them, Xu Jin naturally wanted to strengthen his most powerful Flame Burst.
With a thought, the Star Pattern of the first Star Lamp turned into a Star Burst Technique, and the Star Pattern of the second Star Lamp became a Blast Flame, which are the fundamentals of Flame Burst. So, what to choose for the third and fourth Star Patterns?
Star Transformation? Flame Flower? Or a Spiral Star Pattern?
After some thought, Xu Jin ruled out the Spiral Star Pattern.
The Spiral Star Pattern is a passive Star Pattern, it really doesn't need to be involved in the evolution, Xu Jin could attempt it himself.
He considered merging it with Star Transformation, but after some thought, he gave up on the Star Transformation Star Pattern.
