Hello ,Imho Dingl should rly do that quest ,and send a ticket to support if wants to rly play this character.I had some problem with this particular quest,something as i remember was missing from y bag also at that time ..ppl told me its not an important quest etc and i left it be...around Coldberg map i deccided to set a ticket and i got help from a GM. Because of this quest i could not acces the npc further on to be able to turn in the World Mysteries. Many quests are marked as non important;tho you won't get the next quests in the chain in order to complete everything.Cursed items q its a necesary q,at least it was for me.GL solving your problem ,Dingl.
