From publisher blurb:
Clever Title Using Hack & Class presents eight new character classes for use with The Black Hack, a most excellent roleplaying game that is "super-streamlined" and easy-fun to play. You'll find within:
The Astrologer, a spellcaster who orients his allies toward good fortune.
The Berserker, a warrior whose blood-mad rage bestows fearsome might.
The Goblin Bomb-Lobber, a rabble-rousing anarchist who blows up the Establishment.
The Hengeyokai, a shape-shifting animal who lives among humankind.
The Jester, a spellcasting comic who laughs in the face of danger.
The Monk, a master of mystical martial arts who fights with fists of fury.
The Paladin, a stalwart knight who is dedicated to a holy quest.
The Singerie, an intelligent monkey who excels at aping the actions of others.
Clever Title Using Hack & Class also presents a simple system for adapting the Usage die rules to replace spells per day for spellcasters.
