In addition to Motifs, completing the “Soul Shriven in Coldharbour” quest awards a set of Prisoner’s clothing styles, and you can expect additional unique gear and weapon appearances to become available in the future as well.
Monster Mask and Shoulder pieces will now display their item style as "Undaunted". This style cannot be crafted, and serves only to categorize Monster Mask and Shoulders. For now…
And I hope we get to see other styles (wormcult, maormer, reach winter etc)
Also it would be awesome if we can use parts of costumes as well
