How do you summon Belphagor without a Sigil?
Discussion
You can do a summoning by vibrating his name. You can also visualize Satan's sigil and ask Him to connect you to Lord Belphagor.
If or when you become truly close to a Demon or Demoness, He/She may choose to reveal His/Her sigil to you if it is not listed.
