It could be difficult to follow the last book in particular without having at least listened to the first divine dungeon book. Aside from that Artorian is infinitly better protagonist than Dale in every way.

He’s smart, caring, charismatic, determined, and above all, smart. Did I say smart twice? Yes. I apore dumb protagonists. Dale does dumb shit because he doesn’t know any better. Artorian does dumb shit to test things. To explore the scientific process. To learn. Dale gets handed most of his gains. Artorian, with exception to this book, works for everything he gets. Right down to making his own cultivating technique from scratch. I can’t help but like the guy.
