A Magic essence flask is a potion flask originally containing six doses of Magic essence. It is created by using Magic essence on a potion flask. A player drinking a dose of magic essence potion receives a temporary +3 boost to Magic. 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. 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.
