|Examine||X doses of prayer renewal in a flask.|
A Prayer renewal flask is a potion flask originally containing six doses of Prayer renewal. It is created by using prayer renewal potion on a potion flask. Each dose restores a certain amount of Prayer points over the course of five minutes.
To decant the potion into the flask, one must have at least 6 doses of prayer renewal potion in their inventory, as well as one or more potion flasks. Using the flask on the potion will open a menu to decant them. The optimal inventory setup for decanting potions is 17 4-dose potions and 11 flasks.
Only the original, six-dose potion is tradeable. Once the potion has been partially drunk, no more doses can be added to it. After all six doses have been consumed, the flask will shatter and disappear.
At level 99 Prayer, a full Prayer renewal flask will restore 3,096 prayer points.
If the full, 6-dosed version of this potion is consumed, each dose would cost about 786.5 coins.
