A Zamorak's favour flask is a potion flask originally containing six doses of Zamorak's favour. It is created by using Zamorak's favour on a potion flask. Each dose provides a 10% increase in Hunter experience when hunting jadinkos.
To decant the potion into the flask, one must have at least 6 doses of Zamorak's favour 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.
