The number of Will Runes is vast, with thousands of common ones, and countless more that Wizards have researched themselves.
Generally, when learning Alchemy, one only needs to master some basic Will Runes. However, if you wish to achieve something in Alchemy, you must master more Will Runes.
Will Runes determine your level of Witch Array skills, and the level of Witch Array determines the upper limit of Alchemy. The two complement each other.
Mastering Will Runes requires engraving them in your mind, similar to constructing a Magic Model in your mind.
Duke, holding "Alchemy Basic Introduction," was observing three basic Will Runes related to Magic Power.
The structure of these Will Runes was very complex, looking like randomly drawn symbols with no order.
Duke carefully observed the structure of the Will Runes and then tried to engrave them with Spiritual Power in his mind.
