Dark Elves are very fond of drevient wine, a drink made from the venom of spiders. Astaron, a master brewer, offers to make some for you if you'll bring him the ingredients he needs.
Astaron explains that dreviant wine is brewed from spider venom. He wants to use grapes imported from Gludio a while back by Trader Vollodos. He asks that you obtain 10 spider venom sacs which are the most difficult to find among the ingredients he needs. Hunt spiders in the Dark Forest and return the sacs to Astaron for a reward. Hunt poison spiders, arachnid trackers and prowlers.
