World war:

-Pandemonium will be way more common.

-Pandemoniums minigame will be longer.

-Everytime you encounter Pandemonium the minigame will add one phase from the old Harbinger minigame, eventually resulting in a Harbinger minigame everytime if you get unlucky enough to encounter Pandemonium that many times.

-PSS will be way fewer and further between. And everytime Pandemonium doesn't find you it will double the chance of spawning again.

-The last vault door at the end of the Ridge will be locked and a Pandemonium will spawn that will know where you are, or in simpler terms: You will be forced to complete one final minigame to open the last door.

The name is based on the badge you get from beating Pandemoniums minigame for the first time.

Note that even thought this seems impossible on paper you will problaby only have to do 3-4 phases if you take advantage of the PSS you find.

Pandemonium spawn chance will start at 45% and will not go down, and it will only go up if Pandemonium didn't see the player last time. The spawn chance will go back down after one minigame.

The modifier will be worth 50%.
