I do it because I like to LARP as a wizard like the one in the cover ofthe book. I also have a tome of AMOP and I like to pretend it's an old grimoire and hold it solemnly in my hands as I chant some incantations from it. I do this as a ritual in which I wear a robe I found at thrift store and a pointy hat I got from a costume shop, not a shitty one for children but a good looking one used for plays.
