Well, yes i have somehow missed that ... chilling touch should work the same as pin down, if i remember it corectly. :-/
But Shadow should be able to shoot more than well enough.
Also, if you want to cheese a little bit ... you can allways use NPC stupidity in your advantage ... so far they are unable to understand terain, so if you reach end of that balcony and jump down, they never jump for you (at least they never did on me) but return the same route around.
Then you can easily jump back ... and watch them to run around again ...
Just in case.
