From publisher blurb:
Blackdirge Publishing gets up close and personal with a new prestige class based around the spiked gauntlet. The crimson pugilist is a ferocious close combat specialist, combining a barbarian's fury and a fighter's skill at arms to create a bloody and intimidating warrior. With his spiked gauntlets, he can rend his opponents' flesh or simply hammer them into the dirt with an array of bone-crunching strikes. Vicious in the extreme, the crimson pugilist is an excellent choice for DMs and players looking to construct a brutal, no-holds-barred, barbarian/fighter hybrid.
Master at Arms - Crimson Pugilist contains 7 pages of new d20 material, which includes the following:
A look at the battle glove throughout history
Author's design notes
The crimson pugilist prestige class
Two new weapons: the bagh nakh and the myrmex
