Super prayer flask

A Super prayer flask is a potion flask originally containing six doses of Super prayer. It is created by using super prayer on a potion flask. Each dose appears to restore 70 + (Prayer level * 3.43) Prayer points.

The flask is made by blowing robust glass, requiring 89 Crafting and giving 100 experience. Red sandstone can be mined at Oo'glog and smelted using the Robust glass machine also located at Oo'glog.

To decant the potion into the flask, one must have at least 6 doses of super prayer 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.

At level 99 prayer, the full flask restores 2457 prayer points. Assuming the 3-dose prayer potions, the wyvern bones and the potion flask are bought on the Grand Exchange, each super prayer flask costs 0 coins, or about 0 coins per prayer point.

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.
