The Claw of Nagash (Mortis Engine)

The Claw of Nagash (Mortis Engine) is a Vampire Counts Regiments of Renown war machine unit. Unspeakable evil energy is exuded, both empowering the Undead legions and crippling those who stand against them.

Description
Many Necromancers and liche-lords have risen to kingship over the Undead, becoming so saturated with evil power that their physical forms radiate magic. Some Vampires actively seek out the citadels of those lords who have gone before, hoping to take possession of their remains and to use them against the living. No mere casket or hearse could be fit to bear the remains of one of these masters of the night. Instead, they are enshrined within a Mortis Engine, a cage of fused bone, surrounded by trappings of grandeur and borne to war by a host of spirits bound to the infernal device. Some reliquaries also carry blasphemous tomes to battle, or scrolls of parchment rumoured to have been penned by Nagash himself. Oft-times the Winds of Magic become night uncontrollable when such a fell tome is near. Heavy with evil magics, painstakingly illuminated with such care that their creator's souls have passed into the leaves of human skin that form its pages, these books can be a boon to the twisted practitioners of Necromancy, but also the bane of reckless and unwary spellcasters.

Strategy
