Nah, the "smell of death" mechanics is a myth - necrophage can spawn at any time whether there are corpses around or not. Actually it can even be already waiting at the the map and necrophage cue would even play untill you come close to it.

I did my tests with the baitand 100% times necrophage wouldn't respond to it if there is a "competition. An active competition that is (I actually learned few tricks to deactivate aggro from other bosses in various areas for the bait to work). And after reentering the "baited area" the game would remove said competiton so necrophage could roam freely. Explain this.
