Expose Weakness

Expose Weakness
Type of feat: Class, Epic Prerequisite: Character level 21, Evasion, Epic Prowess Use: Automatic

As a full attack action, the character makes a single normal attack against an opponent (regardless of the number of attacks per round they normally receive). If the attack hits, the target's weakness is exposed: every round for 5 rounds the target takes damage equal to the character's Dexterity bonus (minimum of 1). This damage ignores all damage reductions and immunities. During this time, the target's AC is also reduced by 3. This ability has a cooldown of 6 seconds.

Gameplay Notes
August 2017: Expose Weakness has been reworked so that an on-hit property is added to the weapon. This fixes the auto-hit bug used by vanilla Expose Weakness. Everything else about the custom feat works as the original.

The attack does not use a full round but one attack from a flurry.

Bugs
Wearing a medium or heavy armor takes off evasion feat skill. So when leveling, remove your armor in order to get the evasion feat back and learn Expose Weakness.
