From publisher blurb:
I have a cunning plan! - Baldrick, from Blackadder
A master of cunning, the kingpin guides anyone willing to heed his plans to triumph after triumph. Kingpins often end up as leaders and many become masters of gangs, guilds, or armies. Others become prized advisors, officers, or the power behind the throne. The kingpin trades battle prowess for a myriad of tricks and deeds of cunning, allowing his gang to perform acts of daring no others could do.
The Kingpin is a new 20-level base class for the Pathfinder Roleplaying Game.
