Sexiest man alive. The charmer. Isaac is what you get when you get a max charisma stat. They're just amazing all around. On top of that, they've got sky-high intelligence to back it up. Sure, Isaacs may tend to have a small ego problem, but it's justified because of how purely amazing they are. Very cool people. If you know an Isaac, well first you prolly fell for his charisma check, but also just give that man a well deserved kiss on the lips.
"You see that Isaac guy? Just being in his presence makes me wanna give all my mortal possessions to him."
