Draconis Fundamentum (PDF)
Bow before the mighty dragon gods...
The Draconis Fundamentum puts a magnifying glass on everyone's favorite scaly, flying, (and often fire-breathing) predators. This book's archetypes, feats, spells, and monsters are designed to give players and GMs their dragon fix, finally fulfilling our long-time goal of making it possible to play a party entirely composed of dragon-themed characters, regardless of class or race. Moreover, our new feat chain allows you to gradually transform your character into a dragon, providing a boon to dragonborn and half-dragons alike.
