using a combo of high-level unlockable powers I could, as a Nosferatu, take my own Frenzy (essentially a monstrous panic attack) and just make someone else do it instead. Including humans. And then I could tell them what to do while frenzying because at a high enough level my control of animals extends to people who are frenzying

The wildest high-power combo I could get though is 1) Attack another vampire in plain sight, steal their blood, and kill them in a few seconds with no one noticing and 2) Disguise my aura so hard that no one could ever tell I did it by being immune to mind and aura reading
