During your playthrough of Judgment, you’ll find a number of crafting materials on the streets of Kamurocho, dropped by enemies, or given to you by various NPCs. Some of these can even be purchased from shops, but others a little more difficult to find. Arguably, the most difficult to find crafting ingredient in the game is Mysterious Stones.
You’ll need this item to be able to craft the One-Two Knockout Extract, which in turn is needed to fully complete Iyama’s Friendship Events. So where exactly can you find this rare item? We’ve got a full guide right here detailing all of the locations.
Little Asia
A Mysterious Stone can be found in Little Asia, but you’ll need to use the drone to access it as it is above street level, in the location shown below. There is a chance this will respawn, but it is rare.
Ebisu Pawn Shop
Mysterious Stone is a rare spawn that sometimes appears inside of the Ebisu Pawn Shop just south of Yagamai’s office (as shown on the map below). You can keep resetting the map by taking taxis, then return to the shop to see if one has spawned. You can collect more than one from this location.
In the Alley Near Yagami’s Office
Another rare spawn for the Mysterious Stone is in the alley between the street that Yagami’s Office is on and the street that the Ebisu Pawn Shop is on, as shown below. Once again, keep resetting the map by taking a taxi, and then you can gather more than one Mysterious Stone from here depending on how lucky you are with respawns.
Hotel District
In the Hotel District, there is a small empty lot you can access by squeezing down one of two alleyways, as shown below. There is a chance of a Mysterious Stone spawning here, but much like the other locations, it’s rare. You can get more than one from here if you’re lucky, so keep resetting the map as needed.
Cafe Alps
You first need to have completely befriended Toshizaku Sagara, the manager of Cafe Alps, by completing his various coffee challenges.
After doing this, pop into the break room at the back of the cafe and speak to the staff there. After speaking to them few times (you’ll need to leave the area and return to prompt a new conversation), they will give you a mysterious stone and promise to give you any others they find, so check back in often.
