Undead
The Scourge of Lordaeron. Acolytes summon buildings, which can only stand on blight, and mine gold from a Haunted Gold Mine; Ghouls gather lumber and fight. Undead units regenerate on blight.
Heroes
- Death Knight — Death Coil, Death Pact and Unholy Aura; the classic first hero.
- Lich — Frost Nova and Frost Armor; deadly burst together with the Death Knight.
- Dreadlord — Carrion Swarm, Sleep and Vampiric Aura.
- Crypt Lord (The Frozen Throne) — Impale, Spiked Carapace and Carrion Beetles.
Army and style
- Ghouls and Crypt Fiends early; Abominations, Necromancers, Banshees and Meat Wagons later; Gargoyles and Frost Wyrms in the air.
- Undead play around their heroes: the Death Knight and Lich combo kills enemy heroes in seconds when it lands.
