Doom Knight

Doom Knights are undead warriors. They attempt to fulfill the prophesied deaths of any being so fated by chance, fate, or the order of a Prime Evil.

In-game
Doom Knights are the most basic form of the Oblivion Knight, and are found in of Diablo II, specifically in the Outer Steppes, Plains of Despair normally, and in Chaos Sanctuary as minions of Oblivion Knights. They carry longswords and can deal random elemental damage (spectral) with 60% chance. Although they do not carry a shield with them, they are able to block physical attacks with their sword. However, it does not happen very often. No super unique versions of them exist in the game.
