Type: Wild
Source: Complete Champion
You can imbue your natural attacks with a touch of venom.
Prerequisite: Any two wild feats, wild shape class feature, ability to assume plant form using wild shape.
Benefit: As a standard action, you can expend one daily use of your wild shape ability to envenom your natural attacks for up to 1 round per caster level you possess. An ordinary unarmed strike does not qualify for this benefit; you must have a true natural attack, though it can be the result of a transmutation spell or other shapechange effect.
Poison: Injury, Fortitude negates (DC 10 + 1/2 your HD + your Con modifier), 1d2 Str/1d2 Str.
