Antifire flask

An Antifire flask is a potion flask originally containing six doses of Antifire potion. It is created by using antifire potion on a potion flask.

Drinking a dose will temporarily protect you partially drunk from dragonfire for 6 minutes (36 minutes for per 6-dose flask). It will not fully protect you from dragonfire, so wearing an anti-dragon shield, dragonfire shield or even using the Protect from Magic/Deflect Magic is advisable.

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 antifire 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.

Only the original, six-dose potion is tradeable. Once the potion has been partially drunk used, no more doses can be added to it. After all six doses have been consumed, the flask will shatter and disappear.

If the full, 6-dosed version of this potion is consumed, each dose would cost about, which amounts to per hour.
