Dark Riders

Dark Riders is a Dark Elves cavalry unit introduced in Total War: Warhammer II. Fast and nimble, dodging enemy fire to deliver incisive hit-and-run charges to enemy lines.

Description
In the grim days when armies of Daemons besieged Ulthuan, keen-eyed messengers from Nagarythe kept guard for any signs of a daemonic intrusion. These Dark Riders wore cloaks of black feathers, invoking the raven-headed god Nethu to keep them hidden from the eyes of the enemy. During the civil war, the Dark Riders earned a more sinister reputation. They traveled ahead of Nagarythe's hosts, sowing terror and confusion wherever they rode, burning villages and driving their people into the wilds. In battle, Dark Riders take delight in skirting the enemy flanks to attack war machines and cut lines of supply. They revel in the prospect of running down terror-stricken victims, dragging out every moment of wild panic as long as possible before delivering the final heart-seeking strike.

Strategy
A great and versatile unit for harassing enemy archers/artillery and chasing routing units. Among the elven factions, they are probably the worst light cavalry (comparing to Glade Riders (Spears) and Ellyrian Reavers). However, that still means they are top 3 light cavalry units in the game. This unit has a solid charge bonus at 40 meaning, they are capable of serving as shock cav in a pinch and will inflict a substantial amount of damage when they get the charge, just make sure they are pulled out of sustained combat.
