Secured Armor (Armor Mastery, Combat)

Source Armor Master's Handbook pg. 17
You are adept at using your armor to cover your most vulnerable areas.

Prerequisites: Base attack bonus +11 or fighter level 8th, armor training class feature, proficiency with medium or heavy armor.

Benefit: When you are hit by a confirmed critical hit or a sneak attack, there is a 25% chance that the critical hit or sneak attack is negated and damage is instead rolled normally.

Special: This chance stacks with the light fortification and moderate fortification armor special abilities.

Combat Trick (from the Combat Stamina feat)

Source Armor Master's Handbook pg. 21
If you fail to negate a critical hit against you, you can spend 5 stamina points to cause the attack to deal half damage. (See page 17.)
