Critical reception
John Serba of AllMusic said, "Diabolical Fullmoon Mysticism presents the germ of a soon-to-be-great black metal outfit", calling it "as rancid and unholy as other early Norse efforts, albeit a hair more melodic and listenable than some of its peers", though "one's time is much better spent with subsequent albums."
