I felt drawn to copal incense, I was wondering which demon likes it in particular?
I don’t know if there is one in particular but I find it good generally for evocation as it burns with a fine, white even smoke. Just don’t put too many bits on the charcoal as it can smother and extinguish it. Have you tried frankinscence and myrrh? If you can handle the smell, the thick cloying smoke make actually help the mind get into sync - it promotes a feeling of reverence and would be just as good with goetic demons as angelics & elementals?
I found out who likes copal: is claunek
