Guide/Hint for stuff in PX (that you most likely know already) >> SPOILERS BELOW!
This will include - School (▪ ▪ ▪ ▫ ▫ ▫) (L-8-4-2-5) - Invitation - Final Dreamscape/Confrontation with D-004 - D-007 (w/ 99 coins + Invitation. Not an actual guide for what is called - severe skill issue :l)
School (▪ ▪ ▪ ▫ ▫ ▫) (L-8-4-2-5) On the Fourth Library upstairs, this hint will be shown; ▪ ▪ ▪ ▫ ▫ ▫: L-8-4-2-5 Reset: L-17 ---------------------------------------- What (▪ ▪ ▪ ▫ ▫ ▫) represents;
As in the notepad, L means, Left/Locker. (Blue outline.)
Reset will be where there are 17 locker tiles lined up and that is;
(To save the hassle of - Which is the 17th one?) (It is the one on the right end.) (The puzzle leads to a little surprise for TFB players. Good luck!)
Invitation On the elevator before the flashback with Oliver, there'll be a terminal. Insert a name there that starts with 'B'. (Those who have either read the notepad or managed to get 100 coins will have a clue as to what this would be.)
Final Dreamscape/Confrontation with D-004 Pick up the knife on the second table from the upper right.
There will be a total of a whopping amount of 6 ropes that needs getting rid of. As the first three are obvious, will be skipping them. After getting rid of the first three, pass by the noble outside on the balcony and this will trigger.
After that, there will be a bloodstain near the left entrance, enter from there. Exiting again to the balcony, there will be a lot of hanging bodies but there is a rope among them. Interact with the one below in the image. The second and third are on the same spot as the previous ones that were in the hall. Good luck getting to them!
Get back to the normal dreamscape by going through the same way you came in. And same as the past Amalia, end the party and follow the prince to the balcony. For those struggling with the D-004 fight, use a macro/rapid trigger device/turbo controllers (Yes, Nama encourages the use of such as in the Demonic Mode version, it is just not humanly possible.) Leaving D-004 at a certain HP for a certain amount of time, he will move to the far left and triggering the 'Death' screen is unavoidable. It is still possible to clear the fight with it but it will be very hard. To prevent D-004 from going to the left, make adjustments to never leave the remaining HP at around 60-70 for a short moment, as that will trigger the aforementioned event. (Numbers are estimate.)
D-007 (w/ 99 coins + Invitation. Not an actual guide for what is called - severe skill issue :l) HE WILL BE AS DIFFICULT AS IN THE DEMONIC MODE OF PURGATORY X. GOOD LUCK.
