Benefit: By spending 3 points from his ki pool, you are able to empower you unarmed strikes with a poisonous energy. To use this feat, you must make a single unarmed attack as a standard action and you must declare you are using the feat before your attack roll. If successful with your unarmed strike, your opponent must make a Fortitude save (DC 10 + ½ your level + Wis modifier). If saving throw roll fails, the opponent suffers from the effects of the poison, black lotus extract. The opponent can be cured by successful saving throws and spells such as neutralize poison.

As long as there is at least 3 points in his ki pool, you can make use of this feat.
