|Examine||X doses of Sanfew Serum in a flask.|
A Sanfew serum flask is a potion flask originally containing six doses of Sanfew serum. It is created by using Sanfew serum on a potion flask. Sanfew serum combines the properties of Super restore, Anti-poison, and Relicym's balm (though, unlike the latter, will provide immunity to disease when drunk) potions.
To decant the potion into the flask, one must have at least 6 doses of Sanfew serum 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, 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 3283.8 coins.
