From publisher blurb:
Each character has a full stat block, including campaign traits, a detailed background and personality, and advice on advancement through 4th level. Find one that suits you and you’re ready to play. These characters have been built using a 20-point buy, as many Pathfinder players and GMs prefer it. However, each comes with instructions on how to adjust the stats to a 15-point buy, should your GM wish to use the standard for Paizo’s adventure paths. If your group enjoys an epic fantasy feel for their characters, then adjustments up to a 25-point buy are also available. Whatever your style of play, just a few minor tweaks will have you ready to go.
