If Black Magicians, or left-hand path practitioners want to get real ambitions, im just gonna put this idea into people's heads:
Next time there's an Antifa rally, or rather RIOT, in the United States, why don't you synchronize your ritual to their fighting, and connect to their group Egregore to draw power from it and work willful change upon the world. Or hijack a civil war, or some other macrocosmic conflict to benefit thereby.
Not telling you where I got this idea, or the inspiration for it, but when I read it I immediately realized the great potential in Egregore Hijacking.
This could be a whole new way to do magick.
