So this build with the Chaperone and the Spectral Blades Subclass has been getting pretty popular recently and if you havent seen it or used it I urge you to try it out it is fun as hell. Basically what you are utilizing is the precision slug from the chaperone and Flawless Execution from the Way of the Wraith subclass, and youre combining the slide 1 hit precision kill from the chaperone with flawless execution to chain invis and wallhacks throughout a game.
