This is a picture from the trailer that came out before the game launch. http://imgur.com/PrBNYyQ
It looks to be a human, and they appear to be wearing spiked shoulders, a short leather caped garment of some sort, strapped gauntlets, and a hooded cowl with a scarf of some sort.
It looks freakin awesome, to put it simply. So many of us complain about the lack of variety in medium armors (everything is a trench-coat of some sort!). This is quite different. It lends more to the “I might assassinate you with a knife in the back, or a well-placed arrow in the skull from the canopy of a tree” kind of feel. So much more kitten.
I would like to see the entirety of the armor design mentality re-aligned with what it was in the concept art to be honest. A lot of them made it into the game, but a lot did not. It’s like all the creative juice went into concept art, and never translated into reality. Such a shame….
Please add this armor into the game to start with though!
