I have managed to obtain my third ceremonial Rift helm cosmetic. Getting the helmet made me wish I had an end level hunter to run the rift and obtain the entire armour set, but alas I do not, so I have to console myself with the fact that at least the Rift head pieces from every class are available cosmetically. Perhaps one day all the Rift sets will be available cosmetically, just like the Annúminas sets, but for now, a crafted heavy armour set will have to suffice to complement my new helmet.
Head: Ceremonial Doom-hunter’s Helm, red dye (Rift of Nûrz Ghâshu skirmish cosmetic)
