The reason I like to split my acts into multiple phases is to allow story building in different time periods. If you decide to write a story when the springs are in their first phase, you will only receive the benefits of act 1, while if you prefer to do it when they are in the second, you will receive the benefits of act 2. It allows the springs to have different uses based on when you wish to write the story. You also get the benefits of either discovering the spring first in act 1 or having a group of people in act 3. Overall, I think it adds an interesting layer of creativity if you plan to write about stories set in the past.I gotta ask, why are you doing multipart acts? Couldn't you do everything in one act? Are you splitting so it passes easier?
Thank you for the excellent question 👍
