Yoki is guarding the cemetery. He will forbid you to enter the cemetery. You can give him the following things to enter: 1. * Harlok's stew (get it from Harlok) 2. * An illusion scroll 3. * Weed reefer (Give him for free in the Quest of Distributing the Weed Reefers, or you come to the Monastery by joining the bandit camp for negotiations)
