When using Blink Dagger with Disruptor, a couple of lines (coming out of the battery-thing he has on his back) appear on the direction Disruptor blinked. Not really a huge deal since they don't last too much, but it could help somebody chasing down Disruptor, and predicting, thanks to this lines, in what direction he blinked.

Also noticed it using Force Staff.
