Afflicted Outfits Quest

These pieces of cloth can be looted from Feverish Citizens wandering Venore streets during special raids. Once you have all pieces, use one of them to obtain the outfit. Note that you must have the pieces of cloth in your inventory to let this work, not in e.g. your Depot chest.

Loot Medicine Pouches from Swamp Trolls and trade them with Ottokar for Belongings of a Deceased. By using it you have a chance to get a Plague Mask and a Plague Bell. Once you have one of these items, use it to obtain the respective addon. After using both items and thus completing the outfit, you will get the Achievement Beak Doctor.
