Prerequisite: Critical Focus, BAB +9

Benefit: When you score a critical hit, your target takes a 4 penalty on all Intelligence-, Wisdom-, and Charisma-based skills, as well as concentration checks. Additionally, the save DCs of its spells and special abilities are reduced by 2. These penalties remain until the target is healed of all damage dealt by your critical hit.

Special: You can apply the effects of only one critical feat to a given critical hit unless you possess CriticalMastery.
