Does anyone noticed that the Barbarian got a "Braveheart"style bodypaint / facial paint these past weeks/months?
It happened to my barb but I deleted it to create another one and now it is gone.
Any idea how to get this cosmetic? I have no idea how i got it in the first place, it is a blue facial/body paint.
It sounds like you were wearing the level 1 normal chest armor, cloth tunic. On the Barbarian, it doesn't show as cloth at all, but rather war paint on the chest and face.
Blue is the default appearance. You can dye the armor any color at the Mystic, or transmogrify another chest armor to look like it.
