Built to break open Mass Golems, specifically Fortress Golems. The Spaderazor had offensive powers never to be rivaled during Vza's Envelopment. The design was very unconventional and could endure days of combat before needing to resupply. This let it travel far from City Golems and hunt deep into unclaimed territory. The body held four Golem Pilots, with one in the main canopy and three as backups and operational support.
A lot of kickbacks to traditional War Golems existed within the Spaderazor design. There were a lot of Static Georunes for common functions which eased up on the multitasking done by the Omni Georunes. This gave it efficiency benefits of older designs and flexibility similar to newer designs. There were also a number of dedicated Static Spell Ports to compliment the Omni Spell Ports.
In addition to the standard Scroll Writers the body room contained a built in printing press. The backups could create Spell Cartridges on the fly with this instead of being limited to the handful of Scroll Writers. This gave it incredible adaptability and could be used to push through tight spots. The Spell Ports themselves could also be used to cast Spell Cartridges or have spellcasters inside cast directly to the Spell Ports to be fired externally. This greatly increased the number of targets that could be engaged simultaneously.
The Spaderazor was feared on the battlefield not just because of its incredible design. The operating crew was chosen by Vza directly and known to be very powerful Geometers by themselves. The Spaderazor and its crew were never bested in combat during Vza's Envelopment. Ultimately its end came long after the Fall of Vza when the knowledge to properly upkeep it was lost. Even after it lost its edge, and after it fell into disrepair, people would tell stories of it as if were still around and hunting unsuspecting Golem Pilots.
