my character is killing of people by dipping a piece of jewelry in saxitoxin and scratching them with it. I need to know three things
one: how could my character viably get her hands on some saxitoxin (she is a university student if that helps)
two: is it lethal if placed on the skin or does it need a cut to get transmitted (my character is wearing a piece of jewelery dipped in the stuff, i don't want her to die)
and three how much of a dosage would i need to kill a healthy person.
I did try googleing this but my googlefu has failed me
