Rayne at Light's Hope Chapel in the Eastern Plaguelands will make Dreamwalker Wristguards if you bring her the following: 1 Desecrated Wristguards, 6 Wartorn Leather Scraps, 1 Arcane Crystal and 2 Cured Rugged Hides.
Many heroes fell in the last war and many continue to perish at the hands of the Scourge to this day. From the corpses of the fallen, the armor is stripped and taken back to Naxxramas to be used for unknown purposes.
Recover the desecrated armor and wartorn armor scraps and supply to me the other material components I require and I will craft Dreamwalker armor.
Details
Desecrated Wristguards drop off Anub'Rekhan and Grand Widow Faerlina in the Spider wing of Naxxramas, Wartorn Leather Scraps drop off trash mobs in Naxxramas, Arcane Crystals can be mined, and Cured Rugged Hides are crafted by Leatherworkers.
