This item can be purchased from Quartermaster of the Hand, a Merchant vendor in Nektulos Forest
Plate appearance armor that can be worn by all classes.
Must complete the Bloodlines Chronicle quest Symbols of the Damned in order to purchase.
NOTE: I was able to purchase the armor after having completed ONLY "The Missing Scouts" (still on "Luring Out the Evil", in fact). (Aegin, Antonia Bayle, 6/17/13)
There are no bonuses derived from wearing multiple members of this set.
Note that this is the armor set for Good characters doing the Bloodline Chronicles quests. Evil characters should refer to the Ceremonial Armor of the Brethren.
