What is deep speech dnd?

Deep Speech in Dungeons and Dragons (D&D) is a mysterious and ancient language spoken by aberrations, particularly creatures from the Far Realm such as Mind Flayers and Beholders. It is said to be a language of madness and unknowable depths, incomprehensible to most other beings.

Those who understand Deep Speech are said to gain insight into the true nature of reality and the universe, but at the cost of their sanity. It is often used in rituals and incantations by cultists and followers of dark powers in the D&D universe.

In the game, characters who have proficiency in Deep Speech may use it to communicate with aberrations and other creatures that speak the language, gaining insight or information that others cannot understand. It is a rare and mysterious language that adds a layer of complexity and intrigue to the world of D&D.
