How are death knights’ bodies different from those of other undead like the Forsaken?
As both the death knights and the Forsaken are technically undead, much about their bodies and vital functions – or lack thereof – is similar. Virtually all death knights do not feel temperature or physical pain and have no real need to breathe, rest, or sleep, which are traits they share with the Forsaken [Death Knight, Chapter Five, Legends: Volume One: Fallen, Volume Two: Fallen, Volume Three: Fiend, Quest: They’re Doing it Wrong, Item: Diving Log, NPC: Prince Erazmin Dialogue, Traveler, pg. 96 (softcover edition), Object: Guide to the Side Effects of Reanimation]. That said, it is still technically possible for death knights to sleep if they want to [Object: The Death Knights of Acherus].
Additionally, the death knights and the Forsaken are both capable of bleeding, provided they have some sort of substance running through their veins. The fact that Arthas could still bleed and feel, even as a death knight, enraged him so much that he removed his own heart and threw it down a pit immediately after becoming the Lich King [Quest: The Hunter and the Prince]. Another death knight, Koltira Deathweaver, also complained of internal bleeding at one point [NPC: Koltira Deathweaver Dialogue].
While many of the Forsaken are described as being bloodless, some, including the undead player character, have a type of fluid inside them that oozes out when they are cut [Traveler, pg. 96 (paperback edition), Elegy, Quest: Hiding in Plain Sight, Page: Undead]. Archbishop Alonsus Faol, for example, has no blood as an undead, but it is pointed out that he is “tied together” with ichor [Before the Storm, Chapter Twenty-Six]. Not dissimilarly, a group of gnolls were reanimated after their bodies were infused with a unique type of embalming ichor [Quest: Graverobbers, Quest: Rot Hide Ichor]. Others still, such as the Scourge’s gigantic flesh giants, cannot be created without both blood and embalming fluid to preserve their parts and keep them functioning [Quest: Spill Their Blood].
The biggest question most players have concerning death knights, however, is whether or not they decay like their Forsaken counterparts. The seemingly immaculate appearance of their bodies compared to the Forsaken, many of whom are in a perpetual state of decomposition and often lose limbs, led many to assume that death knights’ bodies are preserved and maintained by a greater degree of necromantic magic [Traveler, pg. 96 (paperback edition), NPC: Forsaken Battleguard Dialogue, Quest: The Wakening, Short Story: Dark Mirror]. This is, in fact, true as Sylvanas once explained that the Val’kyr serving under Arthas raised death knights in rituals so potent that it made their bodies much stronger and hardier than those of traditional undead [Short Story: Dark Mirror].
Some of the original orcish death knights were depicted as rotting corpses, but it is important to note that the orcs’ souls had been placed in already decomposing bodies by the time they were reanimated [Tides of Darkness, Chapter Six, Chapter Seventeen]. In other words, there is no doubt that strong necromancy preserves the death knights’ bodies and prevents them from decaying at the same rate as lesser undead, but the appearance and state of their bodies likely depends on how long after their deaths they were reanimated.
