In Pandora's Tower, each tower has a unique item that can only be found at certain times of the day. When talking with Mavda after finishing a tower, she will give you a hint about the tower you just returned from.
The problem is, she doesn't give you specific times to go hunting. She gives times of day, like morning, evening, or night.
So, the question is, what times of day reference what hours in the day? Or, alternatively, in the event that each tower has a different set of hours to find each unique item, what are those hours?
