So I have blade at rank 5/65 and used the awakening gem on him from act 5 and dumped all my sig stones into him. He’s around sig 60 right now. Should I save my 5 star shards for when his crystal comes back around just to see if I can add to his sig level? Or is it a waste of time? I’ll add that blade is my strongest champ right now and my only R5.
