Train Charisma (using time)

You decide to spend some time honing your social abilities, and decide that regularly buying everyone drinks and trying to socialize is the best way to do it in Cyllian. Of course, you avoid getting too drunk yourself, in part to avoid inhibiting your ability to remember what you learn — don't want to only be able to be social while drunk, after all.

After several weeks of doing this, you start to pick up on some subtle abilities surrounding how you come off to others. You take careful note of the things you learn, making sure to practice them several times so that you can remember them when alcohol isn't in your system.
