There are a lot of bugs when you try to use Necrotic Grip (or Solipsism with Spirit of the Necrotic) with Melee Abilities. If you kill an enemy with a Melee Ability in one shot, it treats it as if the Necrotic Grip killed it, so it doesn’t activate most effects that it would otherwise trigger, despite the Necrotic Grip not even dealing a single point of DoT damage, let alone being the killing blow. I tried to test it out with as many Abilities, Aspects, and Fragments as I could, and found the following bugs (note: it only affects Melee Abilities, not standard Melees, so Perks like Grave Robber still work fine): 1. Heavy Handed doesn’t generate Orbs of Power, [i]except[/i] when using Lightning Surge, or when you kill enemies specifically with the chaining parts of Ball Lightning and Chain Lightning, or with the blast caused by Penumbral Blast. 2. Chain Lightning won’t generate an Ionic Trace when paired with Spark of Ions. 3. Electrostatic Mind won’t generate Ionic Traces after kills with Ball Lightning or Chain Lightning [i]except[/i] when used on a group of enemies. 4. Feed the Void won’t give you Devour after kills with Penumbral Blast, Arcane Needle, Pocket Singularity, Incinerator Snap, or Chain Lightning. 5. Echo of Expulsion won’t cause targets to explode after kills with Pocket Singularity. 6. Iceflare Bolts won’t create Freezing seekers after kills with Penumbral Blast. 7. Whisper of Fractures won’t give you Frost Armor after kills with Penumbral Blast, unless a different enemy is also killed by the AoE blast, and not a direct hit. 8. Arcane Needle doesn’t create a Tangle after killing an enemy. 9. Thread of Propagation doesn’t give your Strand Weapons Unraveling Rounds after kills with Arcane Needle. 10. While Transcendent, Facet of Justice won’t cause enemies killed by Penumbral Blast, Arcane Needle, Pocket Singularity, Incinerator Snap, or Chain Lightning to explode. 11. Using Penumbral Blast with Facet of Command doesn’t reload your Weapon or create a Stasis Shard. There were a few instances in which the Necrotic Grip had no bugs: 1. Heavy Handed works with Lightning Surge, or when you kill enemies specifically with the chaining parts of Ball Lightning and Chain Lightning, or with the blast caused by Penumbral Blast. 2. Impact Induction will properly grant Grenade energy after Melee kills. 3. Ember of Searing still creates a Firesprite on enemies killed with Celestial Fire or Incinerator Snap. 4. Whisper of Impetus will still give you Nimble Arsenal after kills with Penumbral Blast. 5. Whisper of Fractures will still give you Frost Armor, but only if a different enemy is also killed by the AoE blast, and not a direct hit. Also, while testing this, I noticed that, even without Necrotic Grip, killing an enemy with Penumbral Blast will activate Iceflare Bolts, Whisper of Fractures, and Whisper of Impetus, but not Glacial Harvest, Whisper of Hedrons, or Whisper of Bonds. And, in addition, Facet of Devotion didn’t give bonus Light Transcendence Energy on Enemies that were killed with Penumbral Blast or Arcane Needle, despite them being Frozen and Unraveled, respectively.
