How do I get 4 charm at the start of the game? How to I get the option of ‘persuade anyone to take your side in arguments’ in the beginning?
You don’t need 4 charm to get that option in the beginning of the game. It showed up for me everytime. But I never discover its perks.
The final point of Charm can be obtained when you ask Samantha to teach you the finer points of Charm. After she turned Wilson into vampire, tell her that since she took something of yours, she should give you something in return. Usually she will just pay some compensation.
