Antipoison++ flask

An Antipoison++ flask is a potion flask originally containing six doses of Antipoison++. It is created by using antipoison++ potion on a potion flask. Drinking a dose will cure poison and temporarily give you immunity from poison for 12 minutes.

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 antipoison++ 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 on the Grand Exchange. Once the potion has been partially drunk, no more doses can be added to it, but it can still be traded to other players. 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 coins.
