Two chapters ago: I can't feel you where you can collect flarelight, you have to figure it out yourself.

This chapter: the dungeon is called "flarelight dungeon"

To be fair I guess the two adventurers who keep harassing MC are probably dumb enough to not figure it out

Congrats, MC, you just alerted every monster in the dungeon to your presence. This is why games used to have wandering monster checks, exactly for these kinds of shenanigans.
