Improved Sunder

This feat has a chance to reduce the target's Armor Class for a longer period of time than Sunder. It has a cooldown of 15 seconds. Some creatures may be immune to the Sunder effect.

When this feat is activated, a melee special attack is made. If it hits, the victim makes a DC 15 Fortitude saving throw. A failure imposes a -5 AC on the victim for 24 seconds.

Prerequisites: Sunder, Power Attack
