A little advice for a new -> Story of the Fallen God
At some point in the story, you will be tasked with defeating the Guardian of Despair x1200. 

You can complete the quest in the area where you got it (Blackstar Fallen Zone), or (especially if you have less CP) you can move one area down (Star's End) where you can also complete said quest.

P.S.

The new story brings with it a few points for Knowledge. Finding places to get points is not difficult and the in-game hints are sufficient.

Finally, while searching for them, you will once again have the chance to fully admire the game's scenery, creativity and the amazing imagination of the authors... from Pearl Abyss, Ltd.
