Hellcannon

Hellcannon is a Warriors of Chaos siege engine unit introduced in Total War: Warhammer. The Hellcannon has a deadly sentience, firing bolts of eldritch fury over great distances.

Description
Part-Daemon, part-war machine, a Hellcannon is a massive construct of metal that growls and shakes with daemonic sentience. In battle, these arcane engines heave crackling blasts of raw energy that soar through the air into their targets, liquefying anything they touch and sending the survivors insane with fear. Hellcannons are guided by a team of corrupt and sadistic Chaos Dwarfs. These malign warsmiths escort and restrain the Hellcannons into battle, for the Daemons bound within hunger for a banquet of flesh. Such is the Hellcannon's bloodlust that it must be chained to the ground to stop it rampaging towards enemy lines. Even these precautions often prove inadequate, as there is little that can stay a Hellcannon's lust for destruction. The Chaos Dwarfs load their charge by brutally shovelling the bodies of their enemies into the Hellcannon's dire-furnace. Flesh runs like wax as the Daemon-machine's hearth feasts on body and bone. Soon, only the souls of its victims are left, harnessed in the Hellcannon's gullet as crackling bolts of energy that are fired towards the enemy in powerful spasms of malice.

Strategy
A truly unique piece of ordnance compared to what other races can field. They only have one cannon per unit, but the projectile is homing and does very high AP and magical damage. Even smaller flying units will struggle to evade its fire. So while you will never get the volume of fire that other artillery can deliver, each shot is very likely to hit and do significant damage with terrain collisions being the most common reason for misses. The crew is also for some reason unbreakable and it takes some time and effort to kill them off.
