Defenser

Defenser (魔関 (ディフェンサー), Difensā lit. Magic Barrier) is a basic magic spell, and one of the first spells any magician learns—it, along with Magic Ray, are the two defining powers of a magician.

Description
When performing Defenser, the user releases their magical energy outwards, utilizing Shape Transformation in order to mold their energy into the form of a hexagonal structure that surrounds them—before their magical energy reacts with the ambient eternano saturated within the environment, solidifying the structure, causing it to take the form of a hexagonal barrier that surrounds the user's body which acts as a shield in order to defend against the attacks of the enemy. The shield itself is similar to a geodesic dome, made of tessellating hexagons. The shield protects against magic, bullets, explosions, and other projectiles—however, enemies are still capable of passing through it if they nullify their magic. Also, if Defenser successfully guards an attack, it unleashes a spray of light around the dome that does damage equal to the enemy's attack power to anything hit by the light. In fact all attacks can be reflected, with correct timing. The user can manipulate the barrier into a number of relatively simple forms: rectangular planes, cylinders, globes, domes, cones, etc; it is an extremely powerful form of defense. The complexity of the shape is limited by the user's ability to imagine, as in, mentally visualize a particular form and keep it in sharp mental focus: not even the user is able to see the forms that they create. The size of a given magical force projection is also limited by the user's ability to imagine. The smallest force projection they can visualize and maintain the visualization is the size of a marble. The largest solid force projection they can visualize and maintain is about one hundred feet in diameter. The user can project larger force-objects if they are hollow. For instance, they could visualize and project a dome one foot thick about a mile in diameter (five thousand, two hundred and eighty feet) and a dome one inch in thickness the user can project for about three point two miles. Small objects at high speeds become missiles; large objects at slow speeds become rams. The user can make these objects grow or shrink as desired.

In any case, the barriers can be very complex and elaborate barriers, or very simple shaped barriers such as circles or squares. These barriers can also hide the presence of the things it coats or even make the target invisible. However, Defenser is slightly difficult to use has it can only manipulate so many magical particles at a time and it required precise timing—despite this, once the user gets the hang of casting Defenser, it will be incredibly simple to harness it in any way that they wish. However, despite being far more advanced than any other barrier, it still suffers from magical draining. The barrier can only be used for a total of one hundred and five seconds and requires one hundred and twenty seconds to cool down. If the user has no other defensive measures this leaves a window of fifteen seconds where they have no defense against attacks. A special trait of Defenser is that with any Elemental Magic, the user is capable of infusing their element into the barrier, granting it special properties that make Defenser an extremely versatile spell.

Uses

 * Defenser Counter: Defenser is also capable of being utilized as a form of counterattack, allowing the user to deliver damage to the attacker when the user is hit; essentially, it is just as it is labeled; a counterattack. When performing Defenser Counter, the user kicks Defenser away from them upon the moment of the spell being activated, before returning to them as magnetized. This serves not only as a reflector, but also as an unpredictable approach to opponents. If timed correctly, it will trip opponents, leaving them vulnerable to follow-up attacks. Upon contact with the opposing technique, Defenser reverses the opponent's attack, whether it be close-range or projectile, upon them, returning it to sender, causing the user to retaliate in any way that they wish as well. If the attack is a projectile, it will simply be deflected behind them and upwards at about a thirty degree angle. It's worth noting explosive projectiles can still explode and will still do damage if they are struck when the Defenser is dissipated. If the attack is a powerful spell such as a Secret Art, then the attacker will be knocked back at a ninety degree angle. The user is capable of leaping out of the counterattack, allowing them to take the opponent by surprise. Essentially, a Defenser, when used to counter, multiplies a spell or technique's damage by one point five percent when there is a successful counter. If a projectile is reversed several times, then this method of harnessing Defenser will be rendered null and void, as the user loses the energy to retain the stance, and the projectile just passes through the stance and damages the user normally. Defenser is capable of being used for regular offense, as with it, the user is capable of knocking their opponent downwards. Defenser, when used as a counterattack, weaker when used against airborne opponents, and doesn't become invincible. It can travel through enemies unhindered, though. However, since the user kicks it, they cannot hold it in place, meaning that timing is crucial in reflecting projectiles. Note that when Defenser comes back to the user, it can also reflect any projectiles back at any angle at the last second.

Trivia

 * Defenser was based upon the Bubble Shield of the Halo series.
