As far as I know there are no titles for the Warhammer skill. Yet is has it's own skill tree, and affinity. I know the other artifacts don't have titles, but afaik this is the only one with a skill tree all its own. So why not titles. Gotta be easy enough to do. Something like 50 Sheriff,70 Prosecutor, 90 Judge. Or John Henry, or Thor. or whatever. Idk, just seems fun. With all the graphic attention the artifacts are getting I think it's a nice way to polish it up a bit
