Vampire isnt invincible and immortal

Most of people think that Marcy is strong but they also forget the fact that she is a vampire, she can be burnt oleh sunlight, stake through jantung can also kill her, silver bullet can slow her down ( even kill her if it go through the heart) light her on api and let she burn to ashes atau u can cut off her head and hide it somewhere that the body cant find can be a good way too. So what do u guys think?
