Tomb/1.03.24

Dark Elf
Although Tombs produce three different units, you probably wont be building more than a couple of them. This is because the three units they produce aren't exactly game defining - they do have their uses, but more situational or novelty than practical. Despite this, you'll end up with at least one Tomb as the skill trio "Black Ward" is fantastic. Not only does the improved resistance it offers make your units (and Hero!) physically tougher against elemental attacks, but it also makes them more resilient against psyche effects and illnesses, too.
