Guthix rest flask detail.png

Guthix rest flask is a potion flask originally containing six doses of Guthix rest. It is created by using Guthix rest on a potion flask. 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 Guthix rest 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.

Unlike other flasks, all six-doses are 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. Flasks can be combined together, but the empty flasks will still be destroyed afterwards.

If the full, 6-dosed version of this potion is consumed, each dose would cost about 3,659.7 coins.
