In some ways, the Primer of Practical Magic sounds like a typical D&D supplement. From the

In addition to spells, there are numerous new magical items. Over 40 new Ioun Stones convey a variety of powers and skill effects, and dozens of other curious magic items fill the pages of the Primer. These again range from the very subtle, such as a sheath to wear over your tongue so that one can endure the most disgusting repasts without crying out or vomiting (and thus potentially offending the wrong person), or books containing insulting verses so scathing they can bring a strong man to his knees; through such powerful and useful artifacts as the ever lengthening rope; Laccodel’s Rune, which protects the wearer against nearly any form of caustic magic; Mieux’s Pantelloons which puff up to frustrate arrows or darts, and can allow the wearer to float away to safety; or the much feared Schiavona of Kavic which conveys superb fighting ability to even the most inept fencer.
Those players not satisfied with the magical creations of others can dabble with the manufacture of their own Vat Creatures, and through the medium of magic and living flesh, create anything from a comely concubine with whom to while away the twilight hours, to a burly and hirsute guard – beast to chase away uninvited solicitors.
Finally, The Primer includes three remarkable prestige classes for those interested in fully immersing themselves in the Dying Earth milieu. The Sharper is a con artist and a thief, whose natural abilities make it just as easy for her to earn a living taking down marks in any big city as creeping around in the wilderness on a foolhardy adventure. The Diabolist is that rather scary individual who specializes in the control, banishment, and / or binding of Demons and creatures from the outer planes. Thanks to the invaluable contributions of Ian Thomson, The Primer includes several of the unique spells and abilities from the DERPG Demons of the Dying Earth book, from which are formed a deadly arsenal of abilities and skills for the formidable Diabolist. Finally, the mighty Arch-Magician class allows players to flex true magical muscles, and become the kind of character you thought of the first time you ever heard Black Sabbath’s ‘The Wizard’.
