I have all 12 atma (one of each in my inventory) zenith weapon is not equipped. I must have spoken to Gerolt at some point 'cause he asks if I'm keeping Jalzahn busy. But when I talk to Jalzahn (with any of my classes that are over 50 that I have the zenith for) I'm just told that my weapon needs to be an atma weapon. No idea if there's a missing step or something, I've been checking walkthroughs, I'm stuck.

Thanks in advance for any help!
