I can't remember for sure but I think from completing event challenges I might have had enough frags for 2 LOLs in the awakening mega event. I might have then claimed 2 from frags via event souls and I am pretty sure I bought 2 with FC.
So personally I'd be surprised if we got enough frags via challenges/events for more than 2 Odins (maybe 3 if you skip cosmic and other store items?) at the end, but hey I could be wrong, wouldnt the first or last time.
