Recommendation

*gives you a tag* -Just kidding i'm not THAT mean

Have you tried Magi?

It's not very RPG-like, but it has dungeons and stuff like that. I feel like everyone acknowledges Magi but forgets about it, but it's really good.

:)

Yuuuuuh. Already done :( Ugh. Or at least some aristocrat or fief lord stories are good enough for me.

Try these

And you've read Solo Leveling? Since i found them by searching up tags and those were the most popular ones, Solo Leveling includes dungeons and RPG (i think)

Thanks for this list!

You can try

Tomb Raider King
Dungeon Reset
A Returners Magic Should Be Special
Otherworldly Kings Survival Records
The Beginning After the End
A Ranker Who Lives a Second Life

I've read all of these. Thank you so much for the offer!

the beginning after the end is so good, thank you for the list, i’ll try them
