I’ve been reading some stuff by S. Conolly. her sigils for certain entities like Belial are different then the ones that I’ve seen on here and in E.A’s works and from the 72 goetia. Anybody have any input on a sigil being right or wrong?

There can be multiple sigils for any entity. There is no “right” or “wrong,” if the proper entity responds. If you create a sigil using the GD Rose Cross method, you will get the being whose name you sigilized, even though the sigil you created may be different from that created from some other method, or that was in some grimoire.

Traditionalists may disagree though.
