Raging Bolt

Raging Bolt (レイジング・ボルト, Rējingu Boruto): Raging Bolt is a Lightning Magic spell which can be utilized with any form of lightning-based magics; and one of the most powerful of its kind—made famous by a certain Wizard Saint-potential magician whom had turned over a new leaf after a humbling defeat by his guildmates.

Description
Raging Bolt is considered an S-Class Lightning Magic spell thanks to needing an incantation in order to utilize properly; and the fact that it deals indiscriminate damage is another factor in this classification. When performing the spell, the user raises their clenched fist in the air chanting the incantation; "Resounding through the air, the roar of thunder, plunge from the heavens and reap destruction! RAGING BOLT!!!" (鳴り響くは召雷の轟き天より落ちて灰燼と化せレイジング・ボルト！！！, Narihibiku ha Shōrai no Todoroki Ten yori Ochite Kaijin to Kase！Rējingu Boruto！！！). Once this is done, the magic words spoken in order to invoke Raging Bolt cause a powerful resonance; manifesting in the form of the user's magic seal manifesting above the opponent from a considerable height, which begins to spin quickly, the magic words taking the form of an enormous bolt of lightning which drops from the seal at amazing speeds, striking the opponent if its horizontal momentum has not carried them out of the way -and if there are no obstructions in the way.

Upon hitting the opponent, a large shockwave is created with the potential to knock the foe away, at least as much as the lightning itself. This spell has seemingly infinite vertical range and thus can be often used to score victory when an opponent is in the air; leading to easy wins. The strikes multiple times and has a fair amount of upward knockback; however, the thunder portion of the attack is considered a projectile and can be reflected back at the user by a Wave magician or absorbed for healing by an elemental absorption magician. The explosion generated upon impact cannot, however. Raging Bolt can pass through obstructions that are close enough to the magical seal. An interesting property of this is that if this attack connects with the user in mid-air, it can create a wall of electricity to prevent a recovering opponent, best if they try to go for an edge. In any case, at higher levels, the power of Raging Bolt is capable of completely vaporizing a weaker enemy with this enormous strike of lightning that ends in a vicious explosion.
