The Spell Technique known as "Explosion" has its greatest advantage in power, with the high-energy conversion of Magic Power capable of easily blasting through an opponent's Magical Barrier of the same level.
At the same time, its biggest drawbacks are its range and stability. It can only be initiated from the caster as the center, and it's nearly impossible to extend the activation time. Once the Favo Rune structure for an Explosion spell is constructed, it will collapse on its own even without being activated.
As a result, the "Explosion" Spell Technique became somewhat unpopular, as its cost-effectiveness as an offensive method is exceedingly low—requiring one to be at a very close distance to the enemy and to cast several layers of Magical Barrier on oneself to come out unscathed. Even calling it "humorous" seems restrained.
