Gene Alloway reviewed Demons II in White Wolf #37, rating it a 4 out of 5 and stated that "Demons II is the best source for running demons in a AD&Dcampaign bar none. It is a maturelook at a complex group of evil powers and can add a great deal of depth and adventure to a gaming world. It will take some time to wade through, but it is worth the effort. Mayfair has really done TSR a favor here. It has tackled a difficult subject well, with the right approach and professionalism the topic needs. Mayfair and Kevin Hassall have also providedAD&D GM's with an essential resource."
