Adrenaline flask

An Adrenaline flask is a potion flask originally containing six doses of Adrenaline potion. It is created by using adrenaline potions on a potion flask. When a player drinks a dose of the potion, their adrenaline bar will be boosted by 25%.

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 adrenaline 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.

After 6 doses of the potion have been put into a flask no more can be added, even if some of the doses are consumed. After a player drinks every dose of the potion, the flask shatters and disappears.

This can be a very useful potion in combat to give quick access to high damage as it bypasses the need for gradual increase in adrenaline and allows access to threshold and ultimate abilities early in combat.
