You sometimes avoid the most damaging blows.
Prerequisite: Dex 13+, Dodge, Skill Focus (Tumble), base attack bonus +8 or higher, Tumble skill
Benefit: You can attempt to cancel any critical hit made against you. Note the modified attack roll that confirmed that a critical hit has been scored against you, and make a Tumble skill check. If your Tumble skill check result equals or exceeds the confirming roll (with modifications) then the critical hit is instead treated as a normal hit.
