"I speak to the shadows ... and they speak back ..."
Not everyone can become a shadow warrior. More than just combatants, shadow warriors are students of styles of fighting they learn from the shadows themselves. Strange and dangerous; a killer with one foot in shadow, who prefers to fight with weapons that are as much about causing pain as they are felling enemies.
The shadow warrior is a new 20-level base class designed for use with the Pathfinder Roleplaying Game Core Rulebook (using some material from other hardback rules, especially the Pathfinder Roleplaying Game Advanced Player's Guide). It is a combat-oriented class, with an emphasis on fighting effectively with exotic weapons and drawing on the powers of shadow and darkness.
