◈ DEMON IDOL ◈ BY DAVID GAY A GAMIST INTERPRETATION OF THE LEGENDARY ADVENTURE GAME, ADVANCED DUNGEONS & DRAGONS [Art goes here.] October 5th, 2025 version. Non-rules-related file changes made on Oct 21th. [https://demonidol.com](https://demonidol.com) ◈ [david@dtgay.com](david@dtgay.com) These rules are founded in real gameplay: The original Geb Campaign, 3+ years, 8-12 table hours per week, plus sister campaigns by other DMs. From David Gay ( [https://dtgay.com/](https://dtgay.com/)), and from gamers like you. Thank you. The “Demon Idol” rules are totally free of cost. If you paid for this PDF, you’ve been hornswaggled.

Of the two approaches to hobby games today, one is best defined as the realism-simulation school and the other as the game school . AD&D is assuredly an adherent of the latter school . It does not stress any realism (in the author’s opinion an absurd effort at best considering the topic!) . It does little to attempt to simulate anything either. ADVANCED DUNGEONS & DRAGONS is first and foremost a game for the fun and enjoyment of those who seek to use imagination and creativity. " DMG 9 WHAT TO EXPECT It’s my privilege to live in the year 2025. Of all times to live, we’re alive during some fantastic gaming. It’s been a great century for gamers. And It’s my honor to welcome you back, or to welcome you for the first time, to the world of gamist adventure gaming. The main purpose of this version was to convert the Demon Idol website to a table-friendly book/PDF format. That being said, there are several changes, many of which are detailed in the “New in this version” section. Also being said, there are weak points. The tables, for example. But the quest for excellent gaming is an everlasting one. I plan to upload a new version to [DemonIdol.com](DemonIdol.com) any time a change is made. Veterans will notice that this edition marks a refocus on “by-the-book”(BTB) AD&D in several ways (though we have always been almost entirely BTB) . Some rulings were made earlier in our campaign that fiddled with certain rules, such as the multi-class combinations. No more. In every case we made a rule revision, we later realized that the change was more impactful than originally seen. Even the character’s sex is far more interconnected with the rules than might be seen at first glance. Demon Idol is now more BTB than ever. We offer optional, additive extensions in the spirit of 70s D&D, rather than tinker with existing rules. As it should be. This book does not profess to be The Only Way To Game. It simply offers one framework for engaging in the glorious tradition of adventure gaming. I hope you find this latest edition of ◈ Demon Idol ◈ to be the most enjoyable yet.
