Hello! I hope this guide helps you get everything you need. I have all 6 classes here and have written out all the choices I did to beat Vlad with them. You should be able to net quite a few achievements from this as well! I tried to integrate as much as I could. Sorry in advance for any spelling mistakes and let me know if there are any ways I could make this more clear or easier to read!

Huge thank you to Farsight, as their Encounters/Karma guide was very useful when I was keeping track of Evil/Good morality and stats!
