Investigation: Wink Psync
Wink Psync is a simplified version of Psyncing used during Investigations to peek into the mind of the person in front of you. By using Wink Psync, you can uncover lies or learn about a person's worries or hidden secrets when regular conversation yields little results. In this game, it is still an experimental technology used by Kaname Date and Aiba.
Somnium: Key Rules
In Somnium, you enter the dreams of people involved in a case to uncover hidden truths. Each dream world is governed by a set of Key Rules, or Keys. By deciphering these rules, you can grasp the logic of that world, making it easier to choose actions that lead to the truth. At first, the Keys appear blank, but as you progress, the sentences explaining them gradually fill in. In the early stages, experimentation and trial-and-error are essential for discovering the rules. Later, it becomes crucial to act in accordance with the completed Key Rules.
