The only way seems just in top reward of gauntlet.
When you get enough frags for moonchild and create a soul, you will see the soul and next to it the final awakening frags. They come with moonchild. You do not have to earn them beyond earning moonchild in gauntlet. There was a whole stupid thread about this that got locked a month ago. Just get moonchild and enjoy playing.
