Perfect juju mining potion

A Perfect juju mining potion is a potion made using the Herblore skill. It is made by combining a juju mining potion (3) with harmony moss, requiring 80 Herblore and giving 126.5 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 mining flask by talking to Teplin Macagan with a potion flask.

A dose of the potion is believed to last for one hour. While the potion is in effect, each ore mined gives a 10% chance of finding an enhanced stone spirit, which does the same thing as the regular juju mining potion (automatically smelting gold ore and coal), and also automatically banking the ores and bars that you mine. The stone spirit also gives a 10% experience bonus while Mining.
