Perfect juju dungeoneering potion

A Perfect juju dungeoneering potion is a potion made using the Herblore skill. It is made by combining a zamorak's favour (3) with harmony moss, requiring 91 Herblore and giving 127.5 experience. This makes a three dose potion, and it can be decanted into other doses by talking to Bob Barter (herbs). It can also be turned into a six-dose Perfect juju dungeoneering flask by talking to Teplin Macagan with a potion flask.

A dose of the potion lasts for four hours. While the potion is in effect, you do 5% more damage in Dungeoneering, have an increased chance of obtaining journal pages, and get a hidden two-level boost to all skills for opening skill doors.
