D&D 5E Planar Language that gets more intricate

[SkidAce]

I thought there was a language (and I thought it was yugoloths) that the lower level "fiends" could speak it, and as higher level fiends learned/spoke it, it got more powerful and intricate, full of secrets the lower CR creatures could not comprehend.

Like I said, I thought it was official 5e, but I cant seem to find the reference for it. It could be 3rd party, I have several d&d settings, but so far no luck finding what I "remember".

Google found a FR page that claimed Infernal got more and more complicated, but that just did not seem like the same flavor I remember reading.

Going to bed for the day, if anyone has any clues it would sure help.

Is it possible you're thinking of D&D 3.Xe's dark speech? I think that was in the Book of Vile Darkness.

Sounds like Infernal to me.

I actually got rid of Abyssal and Infernal for Fiendish, a universal language like Celestial.

I will check Dark Speech...thanks for the reference.

I found my notes for the idea, but can't seem to find the source...maybe I modified infernal.

I can write prose like that, but I don't think I did?

I like the idea, but I don't know where it came from.

We do Infernal for devils, including the imps, Abyssal for demons, including the obyriths, and Gloomspeak for fiends, including the 'loths.
