Yes, the ravage health effect deals poison damage and can thereby proc the poisoned status effect. The charged trait applies to all damage sources, including poisons.
Does the destro staff improvement to status proc also apply. I know it doesnt explicitly state only magic statuses but dont think it would be much of a stretch for it to exclude the martial statuses.
