Twilight Alchemy III

 uses the Spirits from the Alchemist Spirit skill to help you create Alcohol, Acid Bottles and Bottle Grenades extremely fast. When you begin casting, you will attempt to create 100 Alcohol, 50 Acid Bottles and 50 Bottle Grenades. In order to cast, you require to have all the items you would need to create the items normally, and the success rate is no different than if you made them one at a time. You also need to have a Taekwon in your party.

On iRO, this skill is localized as Spiritual Potion Creation (variant 3).
