Death Knights compose the well armed and equipped shock troops of the Undead. They are just as intelligent as their living enemies, and are wholly dedicated to extinguishing that life on the battlefield.
Death Knights wear plate armor and are identified by their skull masks. Many of the traits they bore while alive have been traded for immense power in undeath.
All Death Knights are immune to Sphere 1 and Sphere 2 spells, with the exception of the spell Ward.
Death Knights deal double damage with their weapons (e.g. 2 damage with one-handed weapons, 4 damage with two-handed weapons).
