80% of killing a good wraith is working around Decoy. For the love of all that is fricken holy please don’t throw a dome the moment you see a ‘wraith’ that pops around a corner. It is almost always, always a Decoy. Also, once you know they Decoy, find out if they are engaging or ‘hiding’. If they are hiding, it can only move so far. Usually it’s to climb up something or hide around a corner/in a bush. If they are not engaging, spread out a tiny bit more. You can also spray rapidly the area where Decoy is formed to find the real one. Just keep shooting it. It will either take free damage or cancel the decoy to warp away.
