Using Natal Chart

[Ass Hole]

I've read people here say that someone's natal chart can be used to do some magic against or for the person. I want to know how...

I'd assume that if you got a hold of someones natal chart you could find out when their planets aren't in their favor and/or most vulnerable and take advantage of it. However, I'm not extremely knowledgeable when it comes to astrology, that just makes sense. Hoping someone else could clarify!
