## Rattlesnake Strike (Combat) *Having observed the ways of a desert viper, you have learned to use Ki in a fashion similar to poison.* **Prerequisite:** Wis 15, [[Improved Initiative]], [[Unarmed Combatant]], [[Stunning Fist]] **Benefit:** You must declare that you are using this feat before you make your attack roll (thus, a failed attack roll ruins the attempt). By expending one of your [[Stunning Fist]] uses for the day, you imbue your next unarmed attack with disruptive Ki that mimics the effects of viper venom. If that attack hits, it deals normal damage and forces the target to make a Fortitude saving throw (DC 10 + 1/2 your character level + your Wisdom modifier). A creature that fails the saving throw takes 1d3 points of Constitution damage. They must make the same save every round for the next 6 rounds, or take an additional 1d3 points of Constitution damage. A successful save ends the effect. This feat can be used only once per round.
