...on the following pages I have tried to make the incompleteness and contradictions presented by TSR inc. in their various books for the Advanced Dungeons & Dragons 2nd ed. role-playing game. I have tried to make the combat rules more understandable and better, as well as developing a more comfortable magic system. It is loosely based on "Spellpoints III" (author: Tim Prestero) found in the Net Wizard's Handbook, 3rd ed. by Jim Gitzlaff.
The Swordhawk rules have always been an adaptation of Dungeons & Dragons. However, they are not merely a set of house rules or minor variations, but a generic re-development of concepts to align the rules with the author's goals of presenting a fast-playing but richly complex game. The 1st and 2nd edition are based on Advanced Dungeons & Dragons 2nd Ed. and the 3rd edition is based primarily on d20 OGL, 3rd Ed.
