Father Inigo Montoy at Light's Hope Chapel in the Eastern Plaguelands will make Shoulderpads of Faith if you bring him the following: 1 Desecrated Shoulderpads, 12 Wartorn Cloth Scraps, 2 Mooncloth and 3 Cured Rugged Hides.
<Father Montoy makes some strange gestures in the air in front of you.>
Blessed boy, have you found the vestments of the fallen? The poor souls whose last breaths were taken on the field of battle - stripped of everything including their dignity.
Bring me the desecrated remnants of the departed along with reagents of purification and you shall know faith.
