A particularly large area of magic is all about the art of illusion. But there are other branches for which illusions are only used as "icing on the top." Mentalism is an example of one that, while it does use illusion, it also adds in real effects that aren't commonly known by the targeted audiences. Hellstromism is a pretty good example, as it has been used in several forms with The Amazing Kreskin and Derren Brown. https://en.wikipedia.org/wiki/Muscle_reading https://en.wikipedia.org/wiki/Muscle_reading Needless to say, Hellstromism lends itself well to illusions (like mind reading), so it is easily confused unless you know the difference. But both names mentioned have had lots of success demonstrating it without disguising it as something else and turning it into an illusion. Hellstromism is a great example of something that is presented as magic, and came about through "occult" knowledge and experimentation.
