A carved snake coils around much of this weapon, its body tensed to strike.

When activated, a venomous weapon coats itself in injury poison (Fort DC 14, 1d4 Str/1d4 Str), which lasts for 1 minute or until your next successful attack with the weapon, whichever comes first.
A venomous weapon functions three times per day.
Projectile weapons bestow this property on their ammunition.
