Quest to gain the Soul Stone which, wrapped with a Bloodied Burun Hide, turns into a Burun Soaked Soul Stone. This gives Noble Weapons the Burun Slayer attribute. These weapons can again be turned into Regal Weapons by completing the Burun Kings quests. In addition, after completing the quest, you get all Salvage Spells (self and other), and, if you damned Nuhmudira before and completed all 3 dungeons, the Gem of Ardent Loyalty. How many parts you have to do to get the rewards, depends partially on if you saved or damned Nuhmudira during the Gelidite Library Quest.
