Not a lot to say here; like the title says, I'm not getting any of my melee back on kills with Necrotic Grip's DoT, or kills on corrupted enemies. Only currently tested on red-bar enemies in the open world, curious to hear if others have had different experiences with different enemies. Also, this has been posted in another thread, but enemies that die to Thorn's DoT do not trigger the spread, while enemies that die to the bullets do.
