Delve is especially bad because it was due to World of Warcraft introducing "Delves". When I see something like this that uses delve as an example, you can bet the research is going to be poor.
I play WoW daily and this is what I always think of when someone brings up the word "delve". It's unclear if Brann would summon more or less nerubians if he were piloted by ChatGPT though.
