There are myriad Sprite abilities. One of them is Alchemy, and it's more fun than a Jelly Rabbit on a sugar high.
You will need to carry Alchemy Clay with you when using alchemy.
First, left-click to open the Sprite menu. Select 'O-Alch' at the bottom.
You can buy the normal Alchemy Clay from an Alchemist. Try out these two first.
*You cannot abandon this quest
Left click to open the Alchemy menu at the bottom of the Sprite list. Every week the alchemy result will be different.
Each piece of Alchemy Clay can be used up to 5 times in a row. It will disappear if the alchemy fails.
After the alchemy, the Sprite will reveal your results. If you want to try again, click on Retry. If you click on Confirm, you will receive the result right away!
*Nia's Textbook is required to complete the quest. If this book is lost, a replacement can be purchased from the NPC Sprite Beginner's Guide Gildhorn near the Kaslow Portal. Kaslow City (126, 271).
*Note that if a Sprite Messenger loses Aruka's Horn of Departure Day or returns Aruka to the portal of Kaslow, look for the NPC selling Sprite Beginner's Guide - Gildhorn and purchase it. Kaslow City (126, 271).
