For what i remember since i only saw the anime and it was a long time ago, he has many attacks that cause instant death.
For example that attack he grabs the heart of his enemies you can still keep going either with Immortality 4(ressurection), 5(Deathless Immortality),6(Parasitic), 7( Undead), 8(Reliant Immortality), 9(Transcendental Immortality) or Mid regeneration and higher (characters with immortality 6 and 7 can survive as long as they do not require an heart)
For his "true death" magic 5(Deathless Immortality), 6(Parasitic), 7( Undead), 8(Reliant Immortality), 9(Transcendental Immortality) or Low Godly regeneration and higher (type 6 immortality works in some cases as long as true death is not directed to the "core" example if an insect is controling a body and true death targets the body the insect should remain alive).
