Perfect juju agility potion

A Perfect juju agility potion is a potion made using the Herblore skill. It is made by combining a scentless potion (3) with harmony moss, requiring 85 Herblore and giving 101.3 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 agility flask by talking to Teplin Macagan with a potion flask.

A dose of the potion lasts for one hour. While the potion is in effect, for each lap of the Hefin Agility Course, there is an increased chance that either the cathedral roof shortcut will be usable, or there will be a light creature on the roof that gives you a reward. Note that the two effects might be activated on the same run.
