Optimise your inventory by buying or creating the new potion flasks. These items act as larger vials for your potions, allowing you to store six doses rather than the conventional four – perfect when conquering bosses.

Should you wish to create the vials yourself, you'll need a brand new resource called red sandstone. With a Mining level of 81, you can mine the non-tradable red sandstone north of Oo'glog (south of the Feldip Hills). You can mine a maximum of 50 red sandstone per day.

Take the sandstone to Oo'glog (after completing the As a First Resort quest), to Rutmir's robust glassmaking machine. You can use the machine to fire the red sandstone into robust glass, which can be blown into potion flasks using a glassblowing pipe, as long as you have a Crafting level of 89. Decant potions into the flasks and feel thoroughly prepared for long combat trips (flasks will shatter once emptied of their contents).

Completed flasks are tradable. We expect entrepreneurs with the Crafting and Mining levels to make a healthy profit, should they choose to sell them on.
