Palaces

About Palaces

In Persona 5, Palace exists when someone has big desire. First, you will have to infiltrate the Palace until you have already secure the path to the treasure. You can complete this within a day or two at fastest, including real-life event where you need to "open path" in the real world. Then, you can send the calling card anytime before the deadline, except for 6th Palace which you have to send ON the deadline. Sending calling card will take a day, except you can still (and only) craft infiltration tool during the night. The next day you will directly go into the Palace. Once you have taken the treasure, the Palace will collapse. So if you need to do anything in the Palace, do it before taking the treasure. You can still do it on the day you going to take the treasure. To avoid spoiler, I will not mention which Palace it belongs to.

1st Palace (Castle)
Minimum day required between mission starts and calling card: 1


2nd Palace (Museum)

Take note that at one point you will have to jump into the painting and travel along it, in case you did not notice. As for the Sayuri puzzle, you will have to pick the one that looks different from others, yet correct. Basically the Sayuri's painting should be red, with tree's branch, and her hair should be visible in front. 

Minimum day required between mission starts and calling card: 3


3rd Palace (Bank)

I would say this Palace's puzzle is probably the easiest. It's mostly on finding clues such as A=1 etc. Each terminal will have 4 characters password which you just have to input based on what you have gotten.

Minimum day required between mission starts and calling card:1
Tip 1: I suggest to note all the codes in a piece of paper so you don't have to keep refer your key items.

4th Palace (Pyramid)
Minimum day required between mission starts and calling card: 1

Tip 1: Try to keep the Pharoah's gem with you all the time until you enter the painting room.

5th Palace (Space)

There will be two puzzles in this palace. First is a time-attack based of puzzle. You will need to stop piston to continue the path, but only for 30 seconds. The second is space-travelling portal thing. Keep in mind the green door terminal are those which will close once you have passed through it. It's a bit like the logic diagram where you "pass through" 1010 will become 0101.. The other 2 terminals are based on switches. I would say this is the most challenging puzzle among all of the Palaces.

Minimum day required between mission starts and calling card: 1

6th Palace (Casino)

I would say this Palace is rather interesting one. It's basically on how you cheat the coins to go higher floor. You will have to play the games in order:

1. Dice game
2. Slot game - I would say this is probably the hardest among the 4 games, cause you will need to run around finding Terminals. Meanwhile it's quite hard to hide as the shadow walking path is quite random. 
3. Maze - I think this is annoying when you first entered. But once you are used to using Third Eye throughout the maze, it's not that hard. 
4. Arena - Honestly, I can't even describe how easy is this compared to others. You will be battling shadows one on one. But seems like their LP is shorter, you can almost OTK each of them except the last one. 

Minimum day required between mission starts and calling card:2 (back-to-back)

Tip 1: Don't become a casino addict. Don't use too much coins, you can't "cheat" the 2nd time. Means if you will to lose the coins, you will have to gamble until you can get back the losses.
Tip 2: Try to make FULL use of Akechi if you plan to get Passionate Listener trophy. Let him down an enemy, enemy down him, finish the enemy, debuff him with items.. as many ailment as possible.
Tip 3: After you have secure the treasure, you have to go to the hideout to talk about sending the calling card. You can leave after the meeting without entering the Palace/Mementos. Otherwise you will not be able to spend time with any of the Phantom gang. 

7th Palace (Cruise)
Minimum day required between mission starts and calling card:1

Tip 1: You can find Hanuman here. Try to scout him and itemize him. It will be the ultimate melee weapon for Ryuji.
Tip 2: Get ready once you have gotten the 5th approval letter from the yakuza. There's no warning and you can't save the game. Heal up your team members with items. You will be forced to engage in 3 battle back to back. 

Mementos Depth/Shrine

You will be forced to enter Mementos on 24th Dec whether you like it or not. You can't do any Mementos quests as well. You won't be able to leave the dungeon until the final boss. However, twins warden will be at the Velvet room entrance to heal you. So you don't have to be stingy with your SP. :)

Minimum day required between mission starts and calling card: Within a single day in "dungeon"

Tip 1: Try to have all the Phantom Thief members' confidants' rank as high as possible before going to Mementos. Haru may be too late, but at least have her with CR2 to use Baton Pass.
Tip 2: You can actually spam your Auto-Recover quite often in this dungeon since each Safe Room will let you get to Twins for healing.
Tip 3: Baal can be found in Mementos Depth. But scouting Baal isn't easy as he doesn't have any weakness. You can only hope to crit him. If you are able to scout him, he can be the ultimate gun for Haru. If you can't get him, there's another persona which is far easier to get, Odin (you will need Yusuke max CR). He may sounds godly, but FUSING Odin (Kali and Abaddon) is freaking simple. Once you have reached the end of the Shrine, the area before is good place to grind. Eventually recruiting the shadows there will be freaking EASY. You can fuse Odin like 10 times if you want to. Odin will be the ultimate gun for Ann. Obviously, you can only fuse one of them inside the dungeon. 

Tip 4: The area before the shrine/final boss is a great area to grind for level. It just takes about half day to get from level 7x to 9x, enough for you to even fuse Lucifer. However defeating them are not that easy task. Good thing only two combination of shadows there. It will either be Mot (weak wind) or Abaddon (weak Nuclear/Psi) with 2 Kali. What I suggest is get Morgana, Ryuji/Yusuke and Makoto/Haru (I prefer Haru because of her One Shot) in your team. Have a Auto-Mataru persona and keep set it as your first persona before ambush and another physical user Persona. Once you enter the battle, you can use severe/colossal on Kali, if it crits, then go for another Kali, otherwise leave it to the next member. When it's Haru/Makoto or Morgana turn, hit Abaddon or Mot with their weakness. Then Baton Pass to MC/Ryuji/Yusuke to hit/kill Kali.  Don't forget even if you are facing with Abbadon team, Morgana can still use Miracle punch on Kali to get +1 move for Baton pass to main physical attacker. When your level is getting too high, you will eventually insta-kill every shadow in ambush. So your only way to grind is to stand in front of the enemy until the "Attack" command shows up. If you are unlucky, you will be surrounded by enemy I suppose. :/
