The Judgement: A finely crafted katana. Unique to modern weapons, its special traits lay in its forging and increased capabilities, rather than the versatility of modern weapons made today. The style of weapon predates The War, and is a family heirloom for the Gilver family. The blade is made of an ancient steel folded and purified countless times in a Dust forge, and in-between each layer is solidified Dust, allowing the blade to react incredibly well with Aura and allowing even a small appliance of Aura to drastically increase its cutting power, and with enough Aura can slice apart Aura and Semblance based defenses in an instant. The blade's durability is legendary, and in the hands of a skilled user is said to be able to cut through anything. The blade is polished with a special dust mixture that gives the blade the colour of the user's aura when aura is applied to it. This is purely aesthetic. The sheath is also sturdy enough to be used as a second weapon for both defense and offense. Due to the blade's unique properties, he can only break through Semblance defenses by physically striking them with the blade, extensions and Semblance powers do not count.

Advanced Aura Manipulation, Gathering Storm: The source of his pride and arrogance. For his whole first year he did not have access to his Semblance, and instead relied on mastering what he could control, and that was his Aura. He mastered his Aura to an extent where he could out-pace any other hunter with Aura alone, but doing it through raw Aura capacity like that was not something he had the capacity to do, so he made and mastered a new system, a flow. The Aura would flow through his body, steadily accelerating and distributing his Aura through his body at an almost lossless efficiency. His Aura this way would require incredible concentration, but as a fight goes on, he becomes more and more powerful. It's no surprise in a duel he prefers to evade and counter-attack at the start. Lucius with well built-up Aura can move at blindingly and almost teleporting speeds for short bursts, though doing this multiple times in a row would easily expend his Aura and require him to re-accumulate his concentration. He can use his aura this way to increase his general speed too, allowing him to slash multiple times at blinding speeds. Most people believed this was his semblance.

Blade Vortex: Lucius is capable of creating slashing storms, either all around or at a distance. He can make them slash straight or curved, and generally has a fair amount of control over their length and distance. He can throw them out in his slashes to extend range, or simply increase the cutting power of his sword drastically, he can call a random storm of them at long distance allowing him to counter-attack even from far away, and use them as a means of countering close range attacks. His control over it is limited due to awakening to it only recently, but he has managed to connect it efficiently enough with his Gathering Storm Aura control, allowing him to naturally increase the size, speed and damage of his appliances of this Semblance the more flow he has.

His strength lies in his close range capabilities, he has the capability to end a fight in a single well-timed strike due to the insane sharpness of his blade, and a battle against him becomes more and more dangerous the longer it goes due to his efficiency at using Aura, where many would be on their last legs, he can still be at full if not higher strength than when he started. Even attempting to block his blade can be dangerous if you aren't observant. The brighter the blade glows, the more dangerous, and the more aura he has packed into the slash. These augmented strikes are fairly projected however, as they require a moment to concentrate extra aura into, but when they land, it can be absolutely devastating. The best way to defend against his blade if you really have to, is to attempt to parry it by striking the flat side of the blade, because it is the edge that is deadly.

Because of the large amount of concentration required for his special way of using Aura, mental attacks can be rather effective at minimizing the threat he poses. The effectiveness of this mental-attack tactic is also not affected by how much Aura he already has flowing, meaning you can send him from 100% to 10-0% concentration with an effective mental attack. It won't decrease the amount of Aura he has, but it will greatly slow the amount of aura he has flowing over his body.

His general combat weaknesses are that his ranged attacks have more delay than say, a bullet, so his ability to strike at a range requires his target to already be occupied. Ideally he wants to be close to his opponent, but he cannot use his dash consecutively without sacrificing some of his concentration, meaning ranged capabilities plus mobility would be his natural enemy.
