Original Dungeons & Dragons (OD&D) Supplement I: Greyhawk.

🔥 Original Dungeons & Dragons Supplement I: Greyhawk (TSR 1975) This is Supplement I: Greyhawk, the very first official supplement released for the Original Dungeons & Dragons (OD&D) "White Box" ruleset. Co-authored by D&D creator Gary Gygax, this volume is arguably the most important of the supplements, adding many rules that became standard for all subsequent editions.

✨ Key Contributions & Collectible Details Game-Changing Content: This book formalized many key parts of the game based on Gygax's home campaign, including:

New Classes: Introduced the Thief and Paladin classes.

Combat: Introduced the modern variable weapon damage rules.

Magic: Added many iconic spells and raised the level limits for magic users.

Authenticity: Genuine TSR booklet from 1975–1979, featuring the $5.00 price and the classic Greg Bell cover art.

Condition: Good to Very Good Vintage Condition. The cover is clean with a natural, attractive patina. It shows minor shelf wear, particularly along the top edge, but remains highly collectible and suitable for any serious vintage D&D collection.

A foundational text in the history of role-playing, essential for fans of D&D's earliest, most influential era.
