Author I feel like I have to tell you the main problem with gamer fics with dungeons. Which is that for a lot of people (especially those who didn't read solo leveling) have no measure of how strong monsters in dungeons are. Even if you classify it and say or describe them as really strong it would still make people feel as if it's just platitudes unless the MC loses because then we would have a measure of how strong it is. If you make it so every time he fights in a dungeon he struggles a lot it would just feel like the MC is not really becoming stronger. There are a cupple solutions from not showing the events that happen in dungeons (which would be the easiest) too, making and or showing feats of the monsters. Also the way you describe actions of the monsters matters. It is not the same saying "it moved behind me before I noticed" compared to "it disappeared from my sight only leaving a blurr. Before I had processed what happened, it was already behind me." Of course for it to mean anything you have to show the level of strength of the MC at that point in time. P.S. Also don't constantly use the dungeons, because even though it would have weight in the plot overuse would make people sick of it. At some point it would only be a way to become stronger and explaing everything that happens in dungeons would be the same as describing training routines again and again. Unless you do something different and special in a dungeon and it matters for the growth of the MC or the plot.
