Hello all the knowledgeable people in this forum. I have a question on demonic black magic curse. If a demon is conjured by sorcerer or requestor for a curse and sent to the target. But the target has strong protection and the demon cannot possess the target. What is the effect on the sorcerer and requestor? Any consequences like boomerang effect or similar? What is the duration of curses usually? Does it need the sorcerer or requestor to "put work" into maintaining the curse? Or once the demon is sent out, it does "its work" until its objective is reached? How about black love curses, any impact on the requestor if the target is protected? Appreciate if the shifus here can shed some light.
