Guild Wars 2

Where do you get it? The only set I’ve been able to find is from the CM vendor. Is there another way to get a set?

The only armor I see on wiki that has a prefix of Shaman is the T2 Citadel of Flame reward armor.

If you mean the “of Shaman” suffix, that is obtained by adding a Rune of the Shaman to any armor.

I could be missing something or the wiki page is not up to date: http://wiki.guildwars2.com/wiki/List_of_armor_sets

You can also get them as drops or buy them from the TP.

Tahlkora’s, Reyna’s or Jalis’ set depending on armor weight.
