v.141 - Cygnus Awakening Update Notes

but there isn't any point to it since you cant extend ss rank... and most of the best monster is ss rank and now s rank is too easy
I can always get s rank after like 5-10 combination atleast one

I rather combine to make new s rank than spening 4 gems to extend new one ..unless im doing for level maybe I would extend then again it might be better to use that who know
