Sekiro: Shadows Die Twice – Part 25: Great Colored Carp
The first thing you need to do here is to talk to the old lady and listen to what she has to say. Next, dive underwater and kill all the carps. By the time you kill all of them, you will have enough scales to get every item in the game. Also, grab all Precious Baits of the area and other loots.
Finally, once you’re done with pretty much all of them. Take the path through the cavern. You’ll get chased by a super big Carp. At that point just swim fast to get away from him and when he’s stopped, go back to take the loot and get to the surface at the waterfall. Rope up to the waterfall. Hit the idol and rest.
After that, enter the building right next to the idol and kill the Nobles inside. Then, rope to the center filled with buildings. Kill the enemies left and go to the big friendly Noble and talk to him. Then, ring the bell and the big Carp will show up. Feed him and talk one more time to the big friendly Noble. He will reward you with a bunch of Treasure Carps.
Now you’ve got to make a choice on who you want to be your friend between the two pot guys; the one you found here and the one in Hirata Estate. It doesn’t really matter which one you pick but based on the vibes they give we’re going for the one in Hirata Estate. So if you’ve made the same choice, travel to Hirate Estate – Estate Path and go to the pot guy. Talk to him and purchase items with scales. Then go back to the Last Communed Idol and travel to Fountainhead Palace – Feeding Grounds.
Ring the bell and wait for the big Carp to show up. Go for ‘Select Truly Precious Bait’ and then ‘Pot Noble Harunaga’s Bait’. After giving him that Bait, travel to Guardian Ape’s Watering Hole. You’ll see the big Carp is now dead. Back to Feeding Grounds. Talk to the big Noble and after that, back to Hirata – Estate Path.
You’ll now notice that the pot guy is transformed into a Carp. Purchase items with scales and head back to the Last Communed Idol and travel to Ashina Castle – Ashina Dungeon Entrance. Buy the Mask Fragment: Dragon from the merchant and then enhance your attack power at the idol.
Lastly, travel to Palace Grounds.
