When I met with the others, I realized that the battle had been quicker and easier than I initially expected.
With some time talking to others it was easy to understand why.
One of the main reasons was that most of these Lower Catastrophe Grade monsters originated from the Monster Wave of a few days ago, that is to say, they were part of these very aggressive and stupid monsters.
Thanks to that they used their great power directly and couldn't fight in a way to use their powers as effectively as possible, they also didn't have any combat experience, and because of that, it was easy to fight them.
In addition, the explosion injured many of them, which made it easier for the others to fight.
There were also many cases of others attacking the monsters while they were still in the air after being thrown by the magic blast which didn't even leave these monsters a fighting chance.
