Sig stones dilemma
I finally got a decent skill 5* (aegon). Already awekened him, took to r3 and and sig 130. I have about 400 5* sig stones, but also have 100 mut sig stones. Should I aweken r5 domino and take her sig as high as many mut sig stones I pull from those 400? Should I take aegon higher with generic sig stones? Or should I leave him as he is atm? I only have r4 skill gem, but don't an r5, so I'm not sure if I will r5 him. I most likely won't, if I will pull any decent 6*, but I'm usually not very lucky with those crystals.
