The Outlaw style is a long-awaited gear style which arrived in ESO with the Thieves Guild DLC in March 2016.
Outlaw Style Motif
The Outlaw Motif can be found in the Delves and world bosses of Hew’s Bane from the Thieves Guild DLC.
The entire Motif may become available in the Crown Store at a later stage as well.
The style item is Rougue’s Soot and can be found by harvesting crafting nodes inside Hew’s Bane.
These concept art images show the Outlaw Style.
These images are already in the game files and show a bit of how the Outlaw style will look in ESO.
