Extreme attack flask detail.png

An extreme attack flask is a potion flask originally containing six doses of Extreme attack. It is created by using extreme attack on a potion flask. Drinking a dose will temporarily raise the player's Attack level by 3 + 15% of the player's Attack level (rounded down).

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 extreme attack 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.

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.
