Advanced d20 Magic

Spellcasters in Dungeons & Dragons and other d20 System role-playing games use a "fire & forget" system of magic first described in the Dying Earth stories and novels of sf author Jack Vance. In the Vancian system, the spellcaster must memorize a spell to use it. Once the spell has been cast, it fades from the spellcaster's memory, forcing the spellcaster to rememorize the spell.{{cite magazine | last =Gygax | first =Gary | author-link =Gary Gygax | title =The Dungeons and Dragons Magic System | magazine=The Strategic Review | volume =2 | issue =2 | pages =3| publisher =TSR Hobbies | location =Lake Geneva, Wisconsin | date =April 1976 }}

Advanced d20 Magic uses a variant system of spellcasting for D&D and other d20 role-playing games. The variant system, called "Dynamic Spellcasting", allows spellcasters to cast any spell they know as often as they wish as a standard action without any special ingredients or other actions. However, spellcasting can drain a spellcaster's physical resources to the point of unconsciousness.

Guardians of Order, producers of the Big Eyes Small Mouth (BESM) role-playing game based on Japanese manga, also created a d20 role-playing game based on Slayers (2003), a Japanese novel series written by Hajime Kanzaka and illustrated by Rui Araizumi.{{cite web |url=http://www.explodedgoat.com/animereview.php?num=9 |title=Anime Review |access-date=May 1, 2007 |publisher=Exploded goat |archive-url=https://web.archive.org/web/20070927042521/http://www.explodedgoat.com/animereview.php?num=9 |archive-date=September 27, 2007 |url-status=dead }} Rather than the Vancian "fire & forget" system of spellcasting used in other d20 role-playing games, this system used a variant called "Dynamic Spellcasting".

In 2006, Guardians re-published Slayer{{'}}s "Dynamic Magic" system as a variant for D&D and other d20 game systems in Advanced d20 Magic, a 144-page softcover book designed by David Lyons and Michelle Lyons, with interior art by Kythera, Anne Rouvin, and Melissa Uran, with cover art by Niko Geyer.{{cite web | url =https://rpggeek.com/rpgitem/54589/advanced-d20-magic | title =Advanced d20 Magic (2006) | website =rpggeek.com | access-date =2021-11-15}}
