Zephyra the Alchemist:
Now try making 1 Air Stone and 1 Windy Healing Potion.
Use Alchemy - Combination to use an Alchemy Cube. You can create Air Stones with it. You can check the number of items you can get beforehand by inserting items in the Alchemy Cube. The more items you have in the cube, the more items you can get.
Windy Healing Potions can be made via Alchemy - Transmutation. You can see the list of items you can make by clicking on Transmutation. Go to Pelu the Grocer for the items you need. Remember that you can only create one when you have all the required items.
