Ingrain's life drain can't kill people who have Die Hard on, as Die Hard will proc immediately after the killing blow like some sort of Last Chance.

Narrating the image for more clarity:
-I did 132 Darkness damage. Enemy was left with 14 HP.
-Ingrain drained 30 HP. Enemy got 'killed'. But Die Hard resurrected them on the same turn.

Assuming this is a bug because if it wasn't, Life Drain (Vampire/Lich) wouldn't kill people either, as it actually does bypass Last Chance and Die Hard properly. And I suggest Die Hard only proccing one turn after you get killed, to prevent such interactions.

For reference, this was a 1v1.

Why would this be a bug? They get reduced to 0 HP and then get back up because of Die Hard when their turn in the status phase comes.
