Finding each of them takes a bit of effort, and you need to complete each of the four character Domains, but it’s worth the trouble in the end. Finding most of them is your ticket to getting the free Fischl skin, before it goes on sale like usual in the shop and costs roughly $20 or so to buy. This is a four-star skin similar to the existing Keqing and Barbara outfits, so unlike the new Diluc skin, it doesn’t come with a suite of special effects.
Genshin Impact Phantasmal Conches locations in Resonant Visions
So far, it seems like you can only find about 14 Phantasmal Conches, at least in the initial set of islands available on the first day of Summertime Odyssey. We’re assuming the remaining six Phantasmal Conches will show up over the weekend as new islands appear, possibly where the new character Domains will appear. What that means for now is that you’ll just have to wait to get the new free Fischl skin, but you can get some other rewards for the first 12 shells.

The remaining Phantasmal Conches are inside the new Phantom Realm character domains or are locked behind puzzles that only unlock once you clear the Domains.
Blazin’ Trails Phantasmal Conches - Day 3 Conch locations
Once you finish Xinyan’s Domain, go back inside. You appear in front of the ice flower, Frozen Soul. Exit the room, and turn left. Enter the door at the end of the passage, and you find yourself in a new challenge Domain area. It’s a series of bloom puzzles, but they’re pretty straightforward. At the end of the first room, you face two Stonehide Lawachurls. Follow the heron apparition after you win the battle, and enter the door it leads you to. Interact with the drum, take the path to another door, and go inside. This time, you face four slimes - two Geo and two Pyro - but you only have to defeat them if you want the chest they guard. At the end of this chamber, adjust the center bloom to point towards the large bloom, then ride the gale up to the top of the nearby rock, where you’ll find the conch. The second conch is a bit trickier, and you probably noticed it show up on the mini-map while traveling around Broken Isle. It’s inside a cave you can only access after finishing Blazin’ Trails. Interact with the drum to change the mountain shapes. You want the one on the right to be shorter than the one on the left. Head into the cave on the northern side of the now-short mountain, solve two torch puzzles, and the conch is on the newly drained ground floor.
Immernachtreich Apokalypse Phantasmal Conches - Day 4 Conch locations
Fischl’s Domain also has one conch, in phase two. After the first object puzzle, you enter a courtyard area with a table near some flowers. The conch is on the table. The second conch only appears after you finish the Domain. Head to the northeastern part of the island, where the pin is on the image above, and speak with the three raven statues. Throw three ore chunks in, and the conch floats to the top.
The Ancient Azure Stars - Day 5 Conch locations
The final Conch is inside Mona’s Domain, the Ancient Azure Stars, but you can only access it after completing her associated quest. Go back inside the Domain, and look for this constellation over a doorway once you arrive. Outside the skin, you can get a range of other rewards for meeting certain Conch milestones, including talent books for the Mondstadt gang. Find four Phantasmal Conches
