On Angel Island, Artificial Intelligence has been improved not only for combat, but also in dialogue from NPC's. NPC's are also able to be queried in various ways, such as your words or actions.
Notably, Tailor and Weaver NPC's are able to teach players things like how to make cloth or where to find cotton or wool. Animal Trainers can tell players where to find various animals or monsters in the world, and will even give the location of ones nearby.
These or only some examples of the types of interactions you will notice in the game thanks to the Intelligent Dialogue system.
