In order to ambush, you have to either lure an enemy to a proper location or go to where you know they will appear and wait in that one spot they will inevitably walk through.
Here's teh problem. Thresh is a spectre and doesn't need passage ways. That, and Lucian will always go to Thresh because he can't just throw a bait to get the Warden to walk in. Thresh doesn't abide by human reasoning. Unless you're offering your own soul to bring him in, that shit's not going to work.
Thresh might not have to play by the rules of reality, but he sure loves tormenting and gloating, so Lucian could just stake out the houses of Thresh’s victims and await the inevitable monologue. We can go at this all day, though, but my point is that blindly chasing Thresh shows a lack of... creativity... in Lucian’s pursuit of something about which he clearly cares.
