I'm working on the Assassin challenge now. Pondering on the Gunner challenge. I think for it I'll use Hallowed, Ibuki, Prisoner and Osiris. Like Rags, I got Eddie and the Convict from the event shouls provided after my first 3 runs. I was surprised as to how easily he dropped. I haven't seen a single primordial talisman yet. I got the serenity set. I've only gotten 70 Eddie fragments from 63 runs so far. Battery is dying do I'll finish the assassin and Gunner challenges tomorrow.
