A Vial is made in the Watchtower Quest by adding a Guam leaf and Jangerberries to a Vial of water. Players must add the ingredients in the follow order: guam leaf, jangerberries, then ground bat bones. Failing to do so will cause the unfinished potion to explode dealing 5 damage and you will be left with an empty vial.
Adding ground bat bones must then be added to create a finished potion, which must be enchanted by the Watchtower Wizard to make a Magic ogre potion.
