The Kestrel body armor is showing visually as the same as Temple Garb on the Mage.
The Peak of the Mountain is showing as a silver/grey plate helm with a halo. (cant find the name of the item offhand).
Unsure if this is intended but so far they are the only two uniques I have used that do not visually match the item picture.
Using both of these on a Mage, have not tested on other classes.
