I've been looking through what I have, and found a good combo and a freighting one
First, there are two I have that let me manipulate darkness, which both become extremely useful once you consider Sticking To The Shadows lets you add the property of stickiness to them. That's not counting Lord Of Shadow: Shadow Double which, being a shadow itself, would have the same property.
Then there's the scary one. Angelic Presence would make anyone who doesn't know drop their guard. You could hit them with anything at that point, but it's really scary when combined with Talent Of Killing.
