Serum 207 flask

A Serum 207 flask is a potion flask originally containing six doses of Serum 207. It is created by using the serum on a potion flask. Serum 207 can be used on Afflicted villagers for small rewards.

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 at Oo'glog.

To decant the potion into the flask, one must have at least 6 doses of Serum 207 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.
