From publisher blurb:
Ready Your Blade!
With the Sword Master, a new 20-level class for Labyrinth Lord and other old-school fantasy role-playing games, you'll be ready to face whatever dangers lay in the dark places and deep dungeons of the world! A blade of steel and a tempered heart are all you need to take on the world.
Sword Master also includes optional rules for use with Labyrinth Lord that will give new combat options to dwarves, elves, fighters, halflings and thieves! A touch of swashbuckling action comes to almost every class that wields a blade with this new supplement!
