Blight Drone
Blight Drones are daemon engines of Chaos sworn to the service of Nurgle, the Chaos God of plagues. Seemingly a bizarre and unsettling cross between larva, flies, machines and daemons, these sentient weapons of war are attracted in swarms to battlefields heavy with the dead (just like flies).
Armed with autocannons and maw-like openings that spew acidic poisons capable of melting through flesh and metal, in their high numbers they can be overwhelming. They have been used in many recent chaotic actions and the Death Guard and the Purge seem to favor these machines, using them to confuse and cower the enemy.
They were in the Pauldrons: The Vidya as the main flying enemy in the Chaos forces. Most players quickly grow to hate the things, mainly because they take an enormous amount of hits to kill (as befits a Nurgle daemon engine), and because of that one time, where you are tasked to deal with two of the fuckers backed by a Chaos Psyker, while surfing the top of a Titan. Sounds cool? Well, it would be if it weren't because of those three enemies being infuriatingly hard to hit, tough to kill when you do, and the Titan lacking any kind of cover what so ever (use the port side tower above its shoulder as a wall). Oh, and the Titan moves all the fucking time, so say farewell to any kind of accuracy.
