At-will, standard action, touch, DC 15+; you touch a poisoned creature or substance and separate the poison from its host. If used on a creature, the poison is neutralized and the creature is no longer under its effects (though damage already dealt is not healed). If used on food, drink, or an object, the poison is extracted and deposited as a visible residue.
