Source: Masters of the Wild
You know how to hit your favored enemies where it hurts.
Prerequisite: Base attack bonus +5, at least one favored enemy
Benefit: Select one of your favored enemies that is normally subject to critical hits. Whenever you attack this type of creature, the threat range of whatever weapon you are using is doubled. For example, a long sword usually threatens a critical hit on a die roll of 19 or 20 (two numbers). In the hands of a character with Favored Critical using it against a favored enemy, its threat range becomes 17 through 20 (four numbers). If it is also a keen longsword, its threat range becomes 15 through 20 (six numbers: 2 for being a longsword, 2 for being doubled as a keen weapon, and 2 for being doubled again by Favored Critical).
Special: You can take this feat multiple times. Each time you do, it applies to a new favored enemy. The effects of this feat do not stack with those of Improved Critical.
