I know that most of you are 3.5 folks, but for the last six months I poured my blood, sweat, and tears into an old-school style magic school hexcrawl and rules supplement. If any of you like old-school D&D rulesets and are a fan of my work, I highly suggest you check it out!Larius Firetongue's School of Sorcery
is part new rules, part sample setting, geared and optimized towards games where the players are apprentices at a magical academy. Within this tome you'll find a cantrip subsystem for dabbler-level magic, new races such as drow and tieflings for a diverse student body, books as a new form of treasure which grant special abilities to readers, and much more! Also included is a hexcrawl environment with 3 full-fledged dungeons and a central school acting as a "home base." Sample NPCs and adventure hooks are accompanied by charts and tables for classroom mishaps, extracurricular clubs, and random encounters when wandering the halls of a magic school!
As of today it's available on Drive-Thru RPG
as a bookmarked, watermark-free PDF for $9.99. If this type of campaign interests you or you know of a gamer friend who'd be interested, feel free to check it out and spread the word!
