Leap of Love/Events

The King in Yellow

Trigger the second week after going above step one of one of the DLC's princess.
Now, you have to complete the event before the third week to avoid game over. I recommand doing it
Go to the town in the morning. Investigate only if you have 12 Prowess or below , else pick the second option. Either way, you get +2 Charms.
Go to the castle in the morning. Ask for more only if you have 12 Charm or below , else pick the second option. Either way, you get +2 Knowledge.
Go to the forest in the afternoon. You need 12 Knowledge or below to destroy the book. If you pick the second option, you'll die at the next feast.

The Flux Turner

Need to be started day one. You need to train once and only once in each location (Training grounds, Market, Library and Forest)
At the 4th day, go to Wander around in the afternoon and pick "I choose to stay by". The automat will give you the Flux Turner which, each night, allow you to rewind time by a day.
If you use it too much, the hounds will come after you.
