Is a Golden Hammer's failure to open a block determined by the difficulty of the challenge or the spoiler's it contains? That is, would the Hammer fail to open "Clear the ???? event" if event 20 hasn't been unlocked, but open it after the criteria changes to "Clear the Flower Blooms in the Echoes event"?
