Whenever you want or need to know any information about the fiction that would normally be told to you by your GM, phrase it as a Yes/No question (Such as “Is there anything hidden behind the tapestry?”) and roll to get an answer. Always phrase questions in such a way that a “Yes” answer is a positive outcome, and a “No” answer is a negative outcome (E.g instead of asking “Did the monster spot me?” ask “Am I hidden from the monster?”). Start with doom at 0.
