Shrunken Goblin Skull Earring  

 

goblin messenger has nothing to do with Grachnist spawn time. Grachnist can spawn anywhere from the main outpost to the tiny ones to jsut walking down the path way i have found him all over. the main outpost is the best way to camp him however because you wont have to go to hell and back to see if hes up. just run all over kill everything in the main outpost and he will spawn many many times most I have was 3 up at once well 4 but 3 were in the camp.
