In theory, you could use any one of the triggers instead of levers. However, one of the triggers that makes the most sense is Magic Braziers. They have 4 states, which allow you to make combinations that are much more difficult to guess. In order to successfully make a Magic Brazier reset, you just need to pick which state you want it to be in and ensure you remove the signal when it enters the next state. For instance, if you wanted the correct state to be Fire, you would add the signal when it’s Fire and remove the signal when it’s Storm. Another benefit to using braziers instead of levers is that the states are much more obvious. This means you could add hints around your house to create a puzzle.
