I have one 10* hero. His name is Dogface.
I have also one 9* hero, Mandrake.
What’s the best practice? Is it a good advice to pump all my green fragments into him till he gets to 10*? Will it pay off in the long run?
He’s at 200 fragments now and I have 600 green ones saved up so within a week or so I could potentially have him promoted to 10.
