I haven't played Elden Ring but I do still have trauma from the underground poison swamp in Dark Souls 1

Those fucking guys with the blow darts

I downloaded it and there's poison slime pouring out of my floppy drive, bravo miyazaki

Blighttown is peak videogame and I long for the day we get another from game that doesn't feature fast travel.

I personally love poison swamps. I used to just wander around in swamps and marshes as a kid.

I ain't afraid of no poison swamp

It should be a Tomb of the Giants pitch dark poison swamp, and regular torches and light sources wouldn't work there. You need a special light source that is a matter of luck to acquire on a given playthrough
