Patch 10.0.5 has added many new transmog items. One of the sets added in the patch is making previously unavailable Legion recolors available to players!
With the exception of the Cloth set, all the sets below are recolors of base PvP Legion sets. These will likely become Trading Post rewards at some point.
Cloth – Highborne Scholar
This set is a white, gold and gray recolor of the Legion Dungeon Cloth.
