Perfect juju prayer flask

A perfect juju prayer flask is a potion flask containing up to six doses of perfect juju prayer potion. It is created by using a potion flask on perfect juju prayer 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, you get 5% more experience for using cleansing crystals on the Seren Stone in the Hefin Cathedral in Prifddinas, and you get 5% more experience for sacrificing bones and ashes on a gilded altar.

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 prayer flask into prayer 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.
