Saw this Genny in Arena with not only wrathful staff 3, but also wrathful staff in her weapon. Was it a waste of medals and stones for this person, or is there some benefits to doing this?
Probably just forgot to switch skills, maybe doing a GHB or something that required her to have a different B-slot. I've refined my Genny's staff for Wrathful as well, but only for the Divine Dew.
