Nolkai's Band

Nolkai's Band is a quest reward on Bloodmyst Isle that cannot be worn or sold, and is not used in any known quest. Due to its name being in gray it can be classified as vendor trash. The importance or lore reference of inscription, if any, is unclear and some players believe it will be uncovered in a future quest and hang onto the item. Note that this item has no sell price.
