This article is about the death knight condition. For the spell, see Endless Hunger.
"The endless hunger will soon take hold of you, death knight. When it does, you will feel pain immeasurable. There is only one remedy for the suffering: the hunger must be sated."[1]
Instructor Razuvious

The eternal hunger[2] or endless hunger[1] is an addiction that afflicts all death knights of the Ebon Blade and gives them the need to inflict pain. If death knights do not regularly inflict agony upon another creature, they begin to suffer wracking pains that could drive them into a mindless, blood-seeking hysteria far worse than the fate of those who suffer from arcane withdrawal.[3]
