Leonard Churchill had previously studied this niche direction of curse magic development, but soon realized it wasn't suitable for him.
Entering the world of curse magic wasn't difficult, but to master it often required a tragic fate.
Ordinarily, such a life pattern would torment someone like a curse for their entire life.
What was most important was this: curse magic was a dark spell that derived power from corruption and evil, its essence being "to inflict the darkness and malice one has suffered onto others."
Card masters who delved deeper into curse magic tended to become more twisted and dark, and their own experiences more tragic.
The curse magic displayed by the Black Tooth Granny was particularly clever.
Even when Leonard Churchill faced her, he felt a fatal threat that made his scalp tingle.
This was also the reason he hadn't pursued the other Black Blade assassins earlier but had wanted to take care of this one first!
