To reach completion, it's not about performing a lot of fancy operations; it's about the result and the potential.
Moreover, producing waste or mundane objects is of no use at all, it just wastes time.
What Embers desire is an achievement that can rival a Heavenly Artisan!
Simply put, just create a Heavenly Artisan!
If one is not enough, then create several more; as long as the achievement is high enough, this blessing will be swiftly completed. Unlike the long accumulation and transformation of the former two, it is a qualitative change that is triggered once the accumulation reaches its limit.
It can be achieved overnight or even in a moment.
Yes, as long as you can come up with a Heavenly Artisan...
Then here's the problem, if I can come up with a Heavenly Artisan, how would I still be stuck at the Transformation Rank? But to break through the Transformation Rank, you must create a Heavenly Artisan...
Thus, it's a deadlock, no matter how you look at it.
