Hey do you found it? If not, you have to complete the main questline of kamasilv up to the quest where you plant the seed into the kamasilv. After that you have to go to The Trace of Krogaldo which is north of Looney Forest. You can Search for the NPC in the NPC Finder Tool. The Trace on the ground should have a questline now to start on. After that you can find the Quest Requirements in the Link https://bdocodex.com/de/quest/6809/3/ . Hope I could help you, i had issues aswell and had to figure it out myself. Check out the Screenshot:
