The greatest advantage of the Spell Formula known as Explosion was its power. Its high-energy mana could easily blast through the Magic Barrier of an opponent of the same rank.
At the same time, its greatest drawbacks were range and stability. It could only be activated with the user at its center, and its duration was almost impossible to extend. Once the structure of an Explosion Spell Formula was constructed with Fawo Runes, it would collapse on its own even without activation.
This made Explosion a rather unpopular type of Spell Formula, because its cost-effectiveness as an offensive method was simply too low—having to get extremely close to the enemy and layer several Magic Barriers over oneself at the moment of release just to escape unharmed made calling it "ridiculous" an understatement.
The most common use of this Spell Formula was for magical girls who knew they could not defeat an Aberrant Beast and chose to perish alongside it. With the resolve to inflict a thousand points of damage at the cost of eight hundred to themselves, they would expend all their mana in hopes of dealing the Aberrant Beast a fatal blow. For that very reason, most magical girls found it difficult to speak favorably of this Spell Formula.
However, quite a few magical girls who believed that "firepower is justice" tirelessly improved upon the original Explosion Spell Formula, constantly attempting to make up for its inherent flaws. Their efforts created more advanced Spell Formulas, expanding Explosion into a genuine category of Spell Formulas and establishing the entire Explosion School.
