Adding M.O.X. to HoM

for some reason i cant add mox to my hom, any reason why?

Did you make sure you had a tapestry up?

yea i just realized i had the tap from another char in account wide mode.

You have to have upgraded a Hero's armor (using things like Cloth of the Brotherhood, etc) in order to add it to the HoM, but I don't know if MOX has any upgraded armor?

MOX doesn't need upgraded armor to be displayed, as you could discover if you looked at the wiki for like five seconds.
