Tattered Robes  

This quest is initiated by examining tattered robes. This item drops on Rhayn T'Dax in The Tombs of Night: A Search for Answers instance.

The first step is to kill Soul Parasites in the Tombs of Night: Retribution. This is the second incarnation of the Tombs of Night, and requires you to have completed a couple of the quests outside at Timber Falls to reach it. After doing this you should examine the robes again.

The second step involves kill Larval Feeders until you obtain 3 drops from them. After that you should examine the robes again.

Finally you must collect 12 drops from Grinnins in the Tombs of Night. These only drop on certain grinnins (fishers, netslingers, sporechanters and weakened grinnins confirmed). After obtaining this you should examine the robes again for your reward, a new robe.
