Flaws are like the flip side of feats. Whereas a feat enables a character to be better than normal at performing a task (or even to do something that normal characters can’t), a flaw restricts a character’s capabilities or imposes a penalty of some sort.
A player may select one flaw when creating a character. After 1st level, a character cannot select a flaw unless the DM specifically allows it. Each flaw a player selects entitles his character to a bonus feat. In other words, when you create a character, if you select a flaw, you can also take one bonus feat beyond those your character would be normally entitled to.

Unlike traits, flaws are entirely negative in their impact on a character’s capabilities.
