Dangerous magik and spirits

Hi all dus any one work with an extremely powerful and dangerous spirit or entity? If yes plz share a little on them and why they are so dangerous

I don’t work with that many spirits,if you want a dangerous and powerful spirit,look into Javajoth/Havayoth/Chavajoth or whatever you want to call him.I was told he was around me but I never invoked or evoked him and I don’t plan to do it soon…Also,Infernal Jinn of „The Book Of Smokeless Fire“ are dangerous,powerful and they are some of the best spirits for baneful magick
