章節 162: Spell And Principle

Angor only did one thing in the past week: rearranging Cleanse spell.

But when explaining to Sunders, Angor naturally omitted the part about how many combinations he worked out. He only concluded it with one simple sentence, "Rearrange the models, see their different effects and find out their connections with each other."

Sunders nodded. "Knowing spells to the root is an essential condition for becoming a real wizard. At the same time, you should remember that such work is valuable, but it takes too much time. For now, you should focus on the 'principle' which builds the spell.

"Take Cleanse for example. Its 'principle' is a simple combination of wind and water, which is easy to comprehend, and you can cast the spell easily. For other cantrips, let's say, another level-0 cantrip, Optic Confusion. For that spell, apart from understanding light and shadow, you also need to know the structure of the human retina and its blind spots.
