Hey everybody, I've already seen that the Death Shroud cloak has been posted, so this is the only one left that i know.
The cloak is called the Pelt of the Dark Young and, personally, i think its much better looking then that Shawl thing.
He spawns in Avelorn, which is, i believe, tier3 Empire/Chaos. It spawns on the road on the south side of the Empire camp. He walks with another non-named bestigor and attacks the Chapter 12 town. Kill him and youll be able to buy the cloak from the Librarians in the capital cities.

There's a screenshot of how it looks like.
Have fun
