Imperial Knights - Rare Knight Armours: Questoris Knight Magaera - The Questoris Knight Magaera is a type of Knight that is most often used as a shock assault unit, breaching the most heavily defended enemy positions, while shrugging off heavy weapons fire and self-repairing even devastating weapon strikes in a few minutes. To aid in this role it is armed with a complex Lightning Cannon, using focussed electromagnetic beams to vaporise infantry and blast apart armour.Questoris Knight Styrix - Housing Machine Spirits which some say became too accustomed to wholesale slaughter during the Age of Strife and the Great Crusade that followed it, many of the more conservative houses consider the Questoris Knight Styrix to be a dark and malevolent pattern of armour, the wanton slaughter it unleashes being beneath a true Knight. Other households hold no such reservations however, and often loose entire formations of Styrix Knights to mercilessly annihilate their foes. Armed with a devastating Volkite Chieorovile and backed up with a Graviton Gun and twin-linked Rad Cleanser, the Questoris Knight Styrix is easily able to eliminate large numbers of infantry at range. In close combat, its immensely powerful Hekaton Siege Claw can smash vehicles and tear buildings asunder with ease, making the Knight a powerful addition to any army.Acastus Knight Porphyrion - One of the most heavily armed and armoured of all Knight chassis in service with the Imperium's forces, few Knight households are able to muster Porphyrion armours, which are seen as symbols of favour by the lords of the Omnissiah's cult, and even the greatest households such as House Raven or House Vymar do not claim more than a handful each as part of their arsenals. The Porphyrion serves not only as one of the most powerful war machines of its kind, but also often as the supreme enforcer of the rule and dominion of a Knight household over its own Scions, many carrying the unique heraldic symbol of the shrouded urn; a dread charge given only to a Knight which has destroyed one of its own brothers in sacred and sanctioned trial by combat over some great issue of honour or malfeasance. There are those within the ranks of the Scions and Seneschals of the Knight households however, who do not agree with the otherwise universal regard in which these rare armours are held. For some of its bulk, and the selection of a purely ranged armament -- no matter its magnitude -- is a drawback as it undermines the armour's adaptability and prevents it from indulging in the glories of hand-to-hand combat, while others stress the size and power of the Porphyrion, which rivals that of a Scout Titan. This Knight represents the outer limits of what a single Human mind can interface with, creating phenomenal strain upon even the strongest willed Scion pilot.Acastus Knight Asterius - The Acastus Knight Asterius was a massive, super-heavy pattern of Imperial Knight deployed during the Great Crusade and Horus Heresy eras. This pattern of Knight was specialised for long-range firepower and destroying fortifications. Of the gigantic Acastus Pattern Knights, some of the largest such war machines still in existence, the Asterius is among the most rare. Like its more common cousin, the Acastus Knight Porphyrion, it boasts an armoured hide near impervious to weapons fire, striding across the battlefield like an angry giant beset by insects, and also wields a pair of twin ancient Conversion Beam Cannons. These weapons are irreplaceable relics of a lost technology, each capable of sundering the walls of mighty fortresses and laying low powerful foes in a single blast. The Asterius is even more immense than most other Knight classes, standing almost as tall as a Scout Titan. Its bulky frame was home to an impressive array of long-ranged firepower, which allowed it to lay waste to the Emperor's enemies from afar.
