The Questoris Knight Magaera is amongst the rarest patterns of Imperial Knight armours ever produced. Magaera type Knights are most often used as shock assault units, breaching the most heavily defended enemy positions while shrugging off heavy weapons fire and self-repairing even the most devastating weapon strikes in a few minutes. To aid in this role, it is armed with a complex Lightning Cannon, which uses focussed electro-magnetic beams to vaporise infantry and blast apart armour.
Amongst the rarest examples of Knight armour produced during the Great Crusade and Horus Heresy eras by the Forge-fanes of the Mechanicum, the Magaera is a marvel of lost technology. Within its armoured frame are relic devices understood by only the most learned tech-savants in the Adeptus Mechanicus, from dedicated repair autosimulacra to the nigh-impregnable Ionic Flare Shield. However, the strain placed on the armour's atomantic reactors leads to dangerous levels of radiation seeping past the reactor's containment shields and, in the event of heavy damage, potentially catastrophic internal explosions. Magaera type Knights are most often used as shock assault units, utilising their deadly Lightning Cannon and Phased Plasma-Fusil to breach the most heavily fortified enemy positions. To aid in this role, Questoris Knight Magaeras are also often armed with a Reaper Chainsword, or sometimes a Hekaton Siege Claw. With its self-repairing simulacra, the Magaera can shrug off the heaviest of weapons fire, making it nigh unstoppable in battle.
