"Curse?"
I don't know any cursing spells, but hearing Lu Chan say this, I don't find myself completely clueless.
"People who are up against Great Impermanence or even those who qualify... their luck tends to worsen. Especially if they are targeted with deliberate malevolence, they are more likely to encounter sudden disasters in life," Lu Chan explained, "A curse is essentially the hope that another person will encounter misfortune. It's not just Great Impermanence or those who qualify; if a demon hunter with strong mana deeply despises someone, and the latter has no means or power to counter the curse, then they will truly experience calamities.
"Your power is flame, Fatian Xiangdi related to high temperatures. Hence, those who are your enemies might encounter disasters related to flames and heat.
"Similar incidents might have occurred in your past life. It's just a matter of whether you've noticed them or not."
