Dousing the Blight is a quest available in Dragon's Dogma: Dark Arisen.
- "The darkness here can befog the eyes of even the Arisen. When you find aught you cannot fathom, bring it to one who has the eyes to descry it."
Purify a cursed item.
This quest is available Pre-Daimon, from Olra's notice board after the quest Call of the Arisen.
Obtain a cursed Bitterblack Weapon, Gear, Armor or Novelty from a chest or monster drop within the Bitterblack Isle dungeon.
The first place to likely find a cursed item is in the Garden of Ignominy, in one of the many chests.
Once obtained, bring it back to Olra in Bitterblack Isle Harbor and have it purified.
