The goetic spirit Samigina, or Gamigin is #4 in the grimoire and I’ll be covering Him in this article.
He appears as a medieval Jester, in green/ red/ black colors and for the rest transparent- His voice, despite me hearing Him, is ethereal and has no intonation.
Samigina is Jupiterian (16° in Sagittarius- uncertain) and the description in the Goetia, stating that He can aid in Necromancy + liberal science, is correct; His speciality is Necromancy, and can secondarily aid one in the latter skill too. Only drawback in working with Him is that He’s prone to changing his way of working or mind in work with the operator. See the video below for more information:
