"A hero can interact with the safe (7 eye or wrench) to crack it"
There are clues spread around the map that the heroes can collect to reduce the number of successes required to crack the safe.
My question: let's say the heroes are down to requiring one more success to crack the safe. If they collect another clue, does the safe immediately crack or is an interact required?
They still need to interact, but they don't need successes
