In May 2025 we presented the all-new Old-School Essentials Advanced Fantasy Bundle featuring the complete and definitive version of Old-School Essentials from Necrotic Gnome. Old-School Essentials Advanced Fantasy is a complete “best of” retelling – it’s Basic/Expert D&D, streamlined and expanded with reams of new character options, monsters, and magic inspired by Advanced Dungeons & Dragons First Edition (1978): assassins, poisons, drow, half-orcs, mimics, xorns, vorpal swords, ioun stones, and even the dreaded tarrasque. Presented in the clear and elegant Old-School Essentials style, and 100% compatible with the Basic/Expert rules, these voluminous digital tomes are perfect for anyone new to Old-School Essentials. And if you already love OSE, check the twelve complete adventures in this lineup, designed by old-school luminaries like Brad Kerr, Diogo Nogueira, Luka Rejec, and many more.
There were three complete rulebooks in this offer’s Starter Collection (retail value $37.50) as DRM-free .PDF ebooks, including the Old-School Essentials Advanced Fantasy Player’s Tome, Referee’s Tome, and Advanced Fantasy Reference Booklet.
Those who paid more than the threshold (average) price also got this offer’s entire Bonus Collection with six more titles worth an additional $65, including Old-School Essentials Adventure Anthology 1 and Adventure Anthology 2 along with four full-length adventures: Halls of the Blood King, Holy Mountain Shaker, Incandescent Grottoes, and Isle of the Plangent Mage.
