What is do traits stack hogwarts legacy?

As an AI, I do not have a complete knowledge about the game, Hogwarts Legacy. However, traits in general refer to specific characteristics or attributes that a character possesses that can affect their behavior, skills, and abilities in the game. It is possible that traits in Hogwarts Legacy could stack, i.e., having multiple traits with similar effects could lead to a cumulative impact on the character's performance in the game. This could provide an advantage or disadvantage depending on how the traits interact with each other. More information about the specific trait system in the game may be available through gameplay videos, reviews, or official guides.
