Ruby: Master scythe wielder and sniper and her weapon is a combination of both, and she is skilled enough in combat to use her gun in CQC and even has an entire fighting style based around doing so, using the recoil of her rifle to propel her and change directions on a dime. She is an expert in combat analysis, being able to look at a person's weapon for no more than a few seconds, identify all of its properties and mechanics, figure out her opponent's fighting style from said weapon, and determine any weaknesses or flaws the weapon or her opponent might have. She has elemental Dust bullets, fire (Explodes and sets anything near it on fire), ice (encases anyone near the point of impact in ice durable enough that Ruby herself cannot break it), lightning (induces paralysis by creating an area of chain lightning around the point of impact), and gravity (significantly more powerful than her other bullets and her own physical AP, and has an AoE around the bullet itself which can inflict damage to the target even if they dodge it just by passing by them). She is able to manipulate her own soul for offense and defense, generating a passive full-body forcefield around herself as well as her weapon, enhancing her senses, granting her regeneration, and providing an extremely strong resistance to heat and cold. She can also weaponize her soul as a Semblance, with her Semblance being Petal Burst, which allows her to break herself down on a molecular level, as well as anything and anyone she is in contact with or comes in contact with, becoming an intangible cloud of scattered molecules. While in this state she becomes significantly faster, enough so to speedblitz people who can normally match her in speed and perceiving the world around her as moving in slow motion, as well as gaining the ability to fly and separate herself into multiple clouds to avoid attacks and disorient opponents, and she can enter and exit this state at will, with it being an instinctive response to do so. She can also use it as an attack, creating slipstreams and tornadoes while in this state, which have enough power to send people comparable to herself in power and strength flying. Of note though, she has a limited amount of Aura, and using her Semblance drains small amounts of it each time, though it slowly regenerates in combat and can be mitigated entirely though the various Aura restorative items she carries. There is some other stuff too like the Silver Eyes, but thats unlikely to come up or even be useful in this battle.
Weiss: Master swordsman and the 'caster' of the team. Her weapon is a rapier which contains numerous types of Dust, allowing her to access a wide variety of elemental abilities. Though she tends to favor ice, she also has access to fire (Allows her to project fireballs, waves of fire, superheat her sword to the temperature of a welding torch, or imbue her sword with fire to exlpode on contact with an oppnent's weapon), lightning (Allows her to project bolts of electricity), wind (Allows her to create localized burts of wind and small tornadoes), gravity (Primatily used in conjunction with her semblance, explained below), light (Allows her to fire beams of light and create hard light forcefields), earth (Allows her to create barriers of stone), and plant. With Ice Dust however she is significantly more versatile, allowing her to freely manpulate ice in the surrounding area, as well as flash freezing water and to a lesser extent generating snow and mist to obscure an opponent's vision. She can project shards of ice, generate swords out of ice, make spontaneous walls and spikes on any surface, encase opponents in ice, cover the ground in ice, and augment projectile attacks so that they explode into ice crystals on impact. She can also imbue her sword with ice, causing her to instantly incase whatever or whoever she strikes or parries with it in a block of ice, and if this attack is used on the ground it instead generates a localized field of ice that harms anyone nearby. She can also combine Dusts to an extent, most notably combining Ice and Light to project lasers and homing blasts of energy that freeze opponents on contact. Just like Ruby, Weiss has an Aura and a Semblance, Weiss' being Glyphs. With her Semblance, she is able to generate glyphs virtually anywhere she chooses at will, on vertical and upside down surfaces, in midair, and even on opponents. She can control the size of these glyphs, the smallest being the size of her finger and the largest being big enough to encompass an airship, she can also control the direction they face even after summoning them, and she is able to summon dozens of them at the same time. The main properties of these glyphs are the manipulation of the fundamental forces of attraction and repulsion, which are represented as white and black glyphs respectively. Attraction Glyphs pull whatever or whoever is within their field of influence, allowing weiss to stand on vertical and upside down surfaces, as well as create restraints by generating glyphs around an opponent's limbs, while Repulsion Glyphs push whatever comes in contact with them away, allowing for instantaneous changes in direction, increased velocity when jumping, and repelling opponents. Weiss can also imbue these Glyphs with Dust, most notably being able to internally freeze and shatter opponents by applying an Ice Dust Glyph to their body, being able to cause a time dilation/speed amplification effect for a person of her choosing by applying a Lightning Dust Glyph to them, and creating fields of anti-gravity or strengthened gravity by applying a Gravity Dust to the general location. She also has a type of Glyph unique to her bloodline; Summoning Glyphs. These glyphs allow Weiss to summon physical copies of monsters she has killed in the past, with her most notable being the Arma Gigas (a 15 foot tall animated suit of armor with a giant sword), the Queen Lancer (a wasp monster the size of a small plane), the Manticore (A giant winged lion), and the Giant Nevermore (A building-sized crow monster). These summons are able to semi-independently of Weiss, allowing her to fight in tandem with them and even being able to act while she is trapped in a stasis field, and she can control them from hundreds of meters away. She can control their size at will, being able to shrink them down to only a few inches in size, and she is able to make them teleport at will. She can also perform partial summons of them to use as attacks, most notably summoning the Arma Gigas' sword to use as both a shield and a weapon and the Nevermore's wings to grant her flight and an AoE projectile attack of feather spears. Of note though, she also has a limited amount of Aura, and using her Semblance drains small amounts of it each time, though it slowly regenerates in combat and can be mitigated entirely though the various Aura restorative items she carries.
Both of them also carry various equipment that allows them to heal and restore their Aura as well as heal themselves physically, including a device called the Revive Ring, which allows them to withstand a blow that would otherwise be lethal, instead restoring them to peak condition physically as well as fully restoring their Aura.
Of note, none of their abilities are magic, everything they do is a mix of soul manipulation and manipulation of natural elements.
