Perfect juju mining flask

A perfect juju mining flask is a potion flask containing up to six doses of perfect juju mining potion. It is created by using a potion flask on perfect juju mining potion with at least six doses of it in your inventory. You can also talk to Teplin Macagan in Oo'glog to automatically fill up the flasks, even in noted form.

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 (including crystal-flecked sandstone). The stone spirit also gives a 10% experience bonus while Mining.

After all six doses have been consumed, the flask will shatter and disappear. Only the original, six-dose potion is tradeable on the Grand Exchange. Once the potion has been partially drunk, no more doses can be added to it. However, if you wish to decant the flask into potions, you need at most four doses of potion left in the flask and an empty vial, decanting a flask into a vial will still make the flask shatter.
