The terrible lich king or the dreadful necromancer from the Ash Plains needs to know what is going on in their enemy’s realm that they dream of tearing apart. That's when the necrogue comes handy. That undead sneaky thing lurks unnoticed in dark corners and doesn't hesitate to cut throats when it’s not quite dark enough to hide. Instinct: sneak around

• Spying for its dark master
• Disappearing in dark corners

When there’s no more room in Hell… Instinct: Braaaaaains

• Attack with overwhelming numbers
• Corner them
• Gain strength from the dead, spawn more zombies
