From publisher blurb:
A collection of down and dirty house rules for The Original Fantasy Roleplaying Game, I've culled these mechanics over the past 24 years from various sources for use in my home games. Now you, too, can use these rules as you see fit, for the low price of only $1 (US).
In Bastard Sword, you'll find rule clarifications for The Original Fantasy Roleplaying Game, as well as new rules for character cultures, non-combat action resolution, determining acting order in combat, yielding in and retreat from combat, combat stances, armor and weapon breakage, variable weapon damage, goal-oriented leveling, and more.
Additiionally, I've included commmentary on what inspired these rules or where they were lifted from, crediting all of my sources along the way.
