Detect Soul

For the duration, you can sense the souls of creatures you can see within 30 feet of yourself. If you sense a creature's soul, you can take the Magic action to learn one thing about their motivations, personality, emotional state, or personal history.

This information comes to you in the form of vague feelings and ideas, so you can't learn specific facts about a creature. For example you might learn that a creature strongly desires something, but you can't tell what that "something" is.
