Unrelated to Clue #7 but re reading #3 and the rule is elements of a story, and the posts were about backwards savages, something seeming innocent, and whirly dirly. Either I’m reaching on it or that definitely seems like Path of the Wicked.
Back to Clue #7, Legacy said on HNN that the rule for 7 was sleight, which is being cunning or deceiving. My guess is still Happy Death Day but maybe it’s another property?
