Blabla realistic blabla scared blabla noob. Fucking white knights, he's been a porter for how long? And he's been to enough dungeons to see this dungeon as a total low tier noobie dungeon, but just because somehow, it should be impossible, but somehow he's never had to face a monster before? He even has some god of wisdom blessing thing and a backup super fighter, yet he's freaking out about a monster that's far less dangerous than the average human (I assume because I mean look at it) and it's using some clubs that's way easier to see and predict than most weapons, it's a chump fight no matter how you look at it.
This is the japanise idiot MC trope showing it's ugly head again, I'm sure most of you have seen it at some point, you know the author is just making the MC more pathetic and you can only guess it's because the author is a low confidence guy shutting himself in all day thinking the world hates him. I think it's this kind of author that makes all those ugly guy + super mega ultimate girl "romance" things, awful.
