I´ve often wondered how intelligent negs (those that frequently attack) are; as some equal them to elementals who are said to only have the intelligence levels of an animal.
More powerful qlippoth, archdemons, are of course said to be extremely intelligent.
But as my attacks have had patterns that reveal more intelligence than that of an animalistic predator this would prove that other qlippoth of the grander ranks might be involved.
It would be interesting to have a demonological listing here and their various subspecies.
