Aside from hand to hand combat,
the magic of Militia's world is weak here.
The power of magic varies depending on the amount of magical power,
but an upper limit exists as a matter of course.
If the magic power exceeds a certain level, the "Flame Grega"
will never be as powerful as the "Great Flame Gusgam", and the "Great Flame Gusgam"
will never be as powerful as the "Hellfire Eradication Cannon Geo Glaze".
The highest level of flame attribute magic, the "Hellfire Annihilation Cannon Geo Glaze," had sufficient firepower in the world of Militia.
At any rate, if it was more powerful than that, it would not only burn the country, but the world (Earth)
But that is not the case here.
Even if it has 100 times the magical power of the Two Laws Tyrant, the "Hellfire Annihilation Cannon Geo Glaze" is not as powerful as the "High Bullet Flame Demon Fierce Heavy Cannon Doguda Azubedara.
Deep magic is qualitatively superior yo shallow magic to the extent that no matter the amount of magic power you add, it can never match up to it.
There is a transcendence between layers
