Destruction Magic

Destruction Magic (壊滅魔法, "Kaimetsu Mahō") is the signature Magic of Setsuna Almark; it is extremely powerful and devastating, compared to even Lost Magic in terms of power. In fact, when first showcased to the public, it was mistaken for a form of Black Arts, used by Black Mage Zeref, though Setsuna quickly debunked this theory; though she confirmed that she developed it by reverse-engineering Death Magic, adding in Crash and Fire Magic to the mix to create this overwhelmingly powerful form.

Usage
Upon a seemingly harmless snap of her fingers, Setsuna amasses a vicious maelstrom of radiant, scarlet and raven magical energy upon her hands or anywhere else she desires; this energy almost appears as if it is a blazing hellfire that will extinguish the souls of her foes. With simple or even complex hand movements, Setsuna launches this powerful energy at her foes in unrestrained waves which usually cover a large distance, directing it towards her target. The energy is touted to chase Setsuna's foe to the ends of the earth, no matter where the foe is standing, even if they possessed high speed, as it would catch her foe eventually. The energy can move at impossible angles, that always manages to reach its target; it will always change its path around any obstacles or pierce through any wall in order to reach its target. However, as a downside, the energy is easy to deflect and dissipate if one knows how to. As it moves though the atmosphere, it gathers and condenses stray magic particles and absorbs it into the energy to increase in speed.

Spells

 * Condensed Destruction: Setsuna can condense and shift the size of the Destruction Magic waves in the form of a small sphere, thus packing more power into a more manageable form to control much easier—or so it seems. Due to the destruction magic being far more compressed within the form of a sphere, it packs far more power and possesses a lot more speed to the point that more often than not, the foe cannot comprehend the velocity of this sphere, enabling Setsuna to vanquish her target without a trace, but the truth is that this condensed form is extremely difficult to control; as little by little, the compression is being undone as the sphere moves around, leading it to randomly accelerate and decelerate, resulting in Setsuna having no control over it's speed and flight path; though it manages to keep it's overwhelming power intact at all times. However, she can focus her power into numerous highly mobile small spheres to circumvent the defenses of her target, resulting in minimal damage to the surroundings.
 * Human-Sized Destruction Magic: On a whim, Setsuna can amass the energy of her Destruction Magic around her body, forming a "casing" of sorts that instills the visage that she is encased in an armour of pure destruction. In truth, she is converting her own bodily properties into Destruction Magic, augmenting her offensive, defensive, and mobility parameters drastically. Now, with a single touch, she can unconsciously or consciously obliterate anything she touches regardless of will; and for the record, most magical projectiles will disintegrate upon impact with her new body. At a moment's notice, Setsuna can use her Destruction Magic emanating from her hands and focus it upon her own body in this form, materializing beings of pure destructive energy shaped in her exact likeness, which can serve as diversions, extra attacking force, or she can even launch these clones at her foes as volatile explosives.
 * Destruction Seekers: One of her most advanced techniques; with this spell, Setsuna channels her Destruction Magic outwards, manifesting it as several small cannon-shaped pods of pure destructive energy, a stained scarlet and jet-black series of hovering turrets that surround her. Using a variant of Telepathy, Setsuna is constantly sending signals from her brain to these pods, creating a communication network that enables her to move them around the area almost effortlessly. These pods unleash condensed blasts of Destruction Magic which appear similar to lasers at her foes; she prefers to use them to attack her foes from long-range and often in conjunction with other spells. They can also be used in group formations for multiple barrages. The one downside to this spell is that maintaining the Destruction Seekers requires a large amount of both mental and magical power, so obviously keeping them out for extended periods of time places a large amount of strain upon her, leading her to only bust out this spell in dire times.
