Light Fortification

Feats

This suit of armor or shield produces a magical force that protects vital areas of the wearer more effectively. When an enemy confirms a critical hit or lands a sneak attack against the wearer, there is a chance that the critical hit or sneak attack is negated and damage is instead rolled normally. The chance is 25% for light fortification, 50% for moderate fortification, and 75% for heavy fortification.
