My first epic boss + was Krampus. I'm on 42 of Glacius and have already leveled my regular Glacius to 35 to unlock the + version. You really have to be around level 100 or have some maxed out epics or 4* armors to beat the epic boss enough to unlock the +. You also need to have 10 friends who are level 100 or so with good armors.
