You are a d4 :

You are bright, perceptive, and driven. You would be considered a blessing to mankind, if you didn't insist on using your powers for evil. You are devious, deceitful, doubtful, and downright dangerous. Assassins can learn a lot from you. If your fellow party members knew how rotten you were, they'd go over and join the bad guys. Justified or not, you are meticulous in your ways: A poison for every person, and a dagger for every back. Much of your day is spent scheming or plotting. The rest of your time is spent trying to convince others that you're simply misunderstood.
