Farming from Yohlon Haven
- Arkjok Ward
- From Yohlon Haven, head north towards the Marga Coast portal and get the mandragor bounty from the priest at the shrine. Follow the path on the map, which leads you to about 20 or so groups of 3 mandragors, including a boss. If you are careful, you can avoid any other foes. Move slowly: about half the mandragor are hidden beneath the surface and seemingly pop-up when you have aggro'd 2-3 other groups already.
