So I broke my own rules and bought event souls, knowing that 11 would be enough. He was not in all these souls but I was able to claim him from the frags. I really feel stupid now after sitting there forever and swiping to get to the red shards in the shop. It would be so much better if the shop could just stay in the same position were you bought your item...but probably the shop needs to reset after each purchase. Too bad!
