Necropolis Knights

Necropolis Knights is a Tomb Kings cavalry Construct unit introduced in Total War: Warhammer II with the Rise of the Tomb Kings DLC. Each serpentine steed is spurred to acts of great brutality in the name of the king.

Description
Necropolis Knights are elite warriors who ride atop giant snake-shaped statues. Their monstrous mounts shatter bones with every swipe of their tails and sink scimitar-sized fangs deep into soft flesh. When Necropolis Knights are awakened to serve in the Tomb King's eternal army, the Necroserpents coiled above their resting places magically slither to Unlife as well; rider and mount are animated by the same warrior spirit, and they move as one being, riding to war in perfect ranks of terrifying cavalry. Necroserpents travel beneath the ground at a relentless pace, emerging from the depths with sand cascading off their forms, warriors standing proudly upon their hooded backs with spears lowered, ready to spill the blood of their foes. Serpentine bodies weave through the battlefield, bladed, fangs and tails lashing out in all directions, leaving a trail of death and woe in their wake. There are few who can stand against the charge of a Necropolis Knight, for they are incredibly powerful and difficult to destroy. As mount and rider share the same soul, only by destroying both can an opponent truly defeat a Necropolis Knight. Few foes are equal to such a task.

Strategy
Necropolis are a strong and well rounded unit of monstrous cavalry. They have solid melee stats, high armour, high armour-piercing, shields, and poison to hamper the enemies combat stats. This makes them a solid generalist that can do well in a variety of situation or in supporting your lord/other constructs in a fight. Because of their well-rounded nature, they struggle to excel at one task without a bonus vs. large or bonus. vs infantry.

Notably, they are buffed by the Necrotect, so if you want to bolster their effectiveness bring one.
