JJBA: 7th Stand User Guide/Walkthrough (Spoilers Ahoy!)

[The Out Of World]

⌈Overworld 2: China⌋

After the plane crashes, the game transitions to the next overworld. There are four kinds of enemies you can encounter here: Murderdolls, Burns, Martial Artists and Green Hornets. The Murderdolls are the regular small ones you encountered back in Japan, attacking in groups of two or three. Green Hornets are bugs that typically are encountered in pairs and are weak to Wind attacks. Green Hornets will poison you frequently, so keep plenty of G.E. Coffee on hand to cure your Poison status. Martial Artists are Short range enemies that fight solo, but have relatively high speed and are fairly evasive. Short range attacks are key to taking them out quickly. Burns are solo enemies that start at Mid range and may move closer.

Emporio's Room

Spoiler: China Exterior

This time the door is hidden in the dark ladder-like structure next to the 7 Eleven in the alley where you find Freu.

Hidden Drugstore

Spoiler: Exterior

Spoiler: Interior

A hidden store that can be entered by interacting with the second wall tile below and to the right of the truck in the alleyway at the rightmost section of the map - the entrance is concealed under a big white horizontal banner. The store only sells stat-boosting items, which come at a very high cost, so you'll only be using this spot on New Game+ runs. The shop has a limited stock of items; you can only buy so many of them in a single playthrough.

Freu & Utah

Spoiler: Freu

Spoiler: Utah

Two enemy Stand Users can be found as mini-bosses in the alleys at the bottom-left corner of the map. A man in a suit is initially blocking the path to Utah, so you have to first defeat Freu before you can talk to him. Freu is the man in the white hood who ambles around slowly. Interacting with Freu will cause him to try shaking you down for your money. Saying "Yes" will cause you to lose your savings (I'm not sure whether or not you can get it back) and saying "No" will trigger a mini-boss fight with Freu and his Stand, Rinocerose. Rino is the more distant and durable of the two, so concentrating your attacks on Freu is a good idea.

Talk to the man in the suit after defeating Freu and he'll let you through to fight Utah. On the first turn, Utah will bring out his Stand, Saints. Saints will summon a Burn to aid Utah in combat. The trio will remain at Mid range, so Short range Stands are at a disadvantage here. Saints will also throw some strong Wind moves your way, so stock up on a couple healing items beforehand. Utah is a rather difficult boss to beat, so do some level grinding until you're at least Level 10 before you confront him.

Jade Garden Restaurant

Spoiler

This is the final location and the exit to the next overworld. Save before you enter the restaurant since you'll be going through two boss battles without any breaks once you step through the door.

I think I am gonna restart my plauthrough. I missed so much stuff.

 

[The Out Of World]

⌈Boss Fight 4: Jean Pierre Polnareff - Silver Chariot⌋

When you enter the Jade Garden Restaurant, you'll see a cutscene of the team's first encounter with Polnareff. But if you look at a table on the right side of the restaurant, you'll see...

Spoiler: Part V

It's Giorno and the gang!

When the group moves to Tiger Balm Garden to fight, you'll have the choice of whether to let Avdol solo Polnareff, to pick another fighter from the team to confront him, or to have everyone gang up on Polnareff. You'll get FP with whoever you choose to fight Polnareff, but ganging up on him will cause you to lose FP with your entire party. Polnareff starts the battle at Mid range and can accelerate himself to give your party a Can't Find status.

Joseph, however, has Hermit Shot's wide range and will have learned Ripple Breathing when you choose him, allowing him to heal 60 HP per turn. If you stocked up on SP-restoring items before the boss battle, you can heal yourself and not have to worry about HP constraints.

After you defeat Polnareff the first time, your party has a rematch against him. Pick Avdol and use the Brainstorm skill to end the fight instantly. Since this version of Polnareff has seven Silver Chariots backing him up, it's nearly impossible to beat him without Avdol's Brainstorm on your first playthrough. You might be able to use Brainstorm to end the first round against Polnareff from earlier if you picked Avdol, but I am not certain.

 

[The Out Of World]

⌈Overworld 3: Harbor⌋

This is the first map where you will have the opportunity to add other characters to your party while wandering around. The various characters will be found at points throughout the level where you can interact with them and choose to switch them with your current second party member, with the exception of Polnareff. Jotaro is in the restaurant by the Inn, Kakyoin is browsing wares at the mats in the bottom-left corner of the map, Joseph is inside the warehouse at the center of the map and Avdol is standing out on the pier to the North.

Emporio's Room

Spoiler: Harbor Exterior

The door is hidden on the corner of the Inn's outer wall.

Hol Horse & Assassins

Spoiler

If Jotaro's level is 10 or higher and you have him in your party, you may have a random encounter when outdoors with three Assassins. These are long-range enemies that deal serious damage with weapons, so only engage them if you have a Stand with Long Range attacks. There's also Hol Horse, but he doesn't do anything of significance.

Emilio & Chicken Shack (Miniboss)
An enemy Stand User is hiding behind one of the pillars at the top-left section of the pier, the one filled with roaming enemies. Once you interact with him, he'll begin fleeing from you at a high speed. You'll have to repeatedly corner and talk to him, which is especially difficult. Emilio is faster but has the least HP of the two, so target him for a quicker victory. He is a Medium Range enemy with a weakness to Fire and Light attacks, so Joseph is a good choice for backup. Chicken Shack is incredibly fast can inflict Poison and Confuse.

Beating Emilio and/or his Stand will earn you a point of good Karma, SP and a Badge of Honor.

Lost Wallet at the Pier
There's a woman on the pier who dropped her wallet in the ocean. Talk to with either Kakyoin or Joseph in your party and you'll gain FP with whichever one is tagging along.

Utah Rematch
Inside the warehouse where you find Joseph, you can encounter Utah again and challenge him to a rematch if you have 40 or more days left on the timer and defeated him in the last map. Utah is weak to Electric, Ice and Light attacks and is essentially a stat-boosted copy of himself from China.

Sushi
Take Avdol to the sushi bar in the top-left corner of the central warehouse for 1 FP.

Free Stuff
If you're a female character and have Kakyoin in your party, talk to the shopkeeper he was standing in front of for a free item and FP.
