Wrong website. This is not a JRPG or anime website.
But if you know this then....
Da fuck? No! Stop! Just no.
And people wonder why I'm such an Grim Trad magician killjoy.
The actual traditions of Western magic include Hermeticism, the Solomonic grimoire traditions, Renaissance Neoplatonism (and then later Thelema - but much of the 20th century cluster fuckery of batshit started there too.).
Traditional pre-20th century Western magic magic operates through contacting and communicating with spirits through using a language of correspondence, symbolic analogy, myth, sympathy, intention, geometry, timing, and invocation / praise songs. -NOT cannibalism or physical consumption of human organs to gain anime "mana points" to level RPG stats or shoot magic electricity Bullshido from your finger.
Stop paying attention to media brain rot - anime, anime, gaming, and horror and fantasy fiction. All fun things. I work in video games, but i dpont confuses them with the Grimoires.
Amassive chunk of what passes for "the occult" or "magic" on the internet today comes straight out of dark fantasy media, shonen anime (Jujutsu Kaisen is a huge offender here with eating cursed fingers), video games, and horror fiction. So now younger or hyper-chronically online people , and the seriously mentally ill, frequently conflate RPG mechanics where eating a monster heart grants +10 Strength with actual historic Wstern Magic.
