We want to repeat the chapter 5 all the times we need to because we skip all the kinematics and gain time.

1. Beat chapter 5
   
2. If you need to interact with some object after the final battle, interact
   
3. Wait for the saving icon on the top right corner and immediately press esc button
   
4. Keep waiting on the menu until the saving icon disappears
   
5. When the saving icon is gone, just go to the main menu and press continue game. You will replay the chapter 5.

I won 8-9K per game. Try to use all the skills in each fight (it is not necessary to use the 4 different magic of each sword) and try not to take any damage.

It is very important to immediately press the esc button to make sure that the kinematics does not continue and the game shows us the end.

Therefore, once esc is pressed, it is important to wait in that menu until the save icon disappears, since that will confirm that the game has been saved, otherwise we will repeat the chapter but without that experience gained.

No damage in battles is important to gain more experience.

Hope the guide is helpfull. If someone needs more help, just write a comment.
