Zephyra the Alchemist:
Oh! Learn about Alchemy? Fine, let me explain.
Alchemy is divided into Combination, which makes Air Stones, and Transmutation, which uses Air Stones or Material Realm items to make Potions, Enchant Scrolls, Life Stones, and Dyes.
You must have the power to control the wind spirits as a child of Sayha, but the amount of control needed for Alchemy calls for an Alchemy Cube.
"Interesting. Go on."
