• Here's a Buffy the Vampire Slayer test that's meant to be extra challenging, and to inspire reflection. Some questions are cut and dried, but many are a matter of perspective and are really more interesting for the question than the answer. There are four variables named after the aspects of uber-Buffy from season 4: Spiritus (spirit); Animus (heart); Sophus (mind); and Manus (the hand). Beat 60% in at least one category to advance beyond "Potential" status.
