The Summertime Odyssey event that came alongside update 2.8 has begun, alongside the lengthy quest needed to start the limited-time event. Once the quest is complete, you can begin an event quest titled Resonating Visions. This quest will allow you to earn a new costume for Fischl, amongst other valuable rewards. This guide will explain how and where to find all 20 Phantasmal Conches in Genshin Impact.
All Day 1 Phantasmal Conch locations
The Phantasmal Conches are a unique item placed around the Golden Archipelago region that is open during the Summertime Odyssey Event. Each day after the Genshin Impact reset, new Conch locations are added to the game. A total of 16 Conches is needed to unlock Fischl’s new outfit for free. This event will feature 20 Phantasmal Conches to find and collect.
Broken Isle Day 1 Conch Locations
To begin your quest, head North from the starting camp site until you reach the Broken Isle.
1: Look for this conch while traveling on the road between the two mountains.
2: From the first Conch, the second one is visible slightly to the north resting on a boulder.
3: After retrieving the second Conch, travel along the shoreline to the strip of land connecting the two islands. It will be on a rock stuck in the sand.
4: Continue crossing and follow the shoreline of the second island to the southeast edge. The Conch will be near a wooden gate and training dummy.
5: Travel southeast across the ocean until you reach the island at area five on the map above. The Conch will be in the center of the island campsite.
This will wrap up the Broken Isle locations. Hop on your boat and travel east until you reach Twinning Isle.

6: The sixth Conch will be near the beach on the western side of the island. It can be found on some rocks near the massive cliff.
7: After grabbing the previous Conch, climb the cliff ahead until you reach the very stop. A narrow strip of land will connect the two ridges; the seventh Conch is located on this land bridge.
8: Head to the top of the second ridge and look across the ocean at the two islands to the south. Leap off, glide to area eight, and find the Conch near the shoreline.
After grabbing the eight Conch, travel south to Pudding Isle or use the teleport if you have the fast travel point unlocked.

10: Leap down to area 10, and the Conch will be resting on a rock stuck in the sand.
11: The final Conch is easy to find. Travel along the shoreline to the island’s western side, and it will be on the beach.

12: This Conch is located near the small pond below the prominent ridge above.
13: After grabbing the Conch near the pond, climb the rock wall above. It is a daunting climb, but after you reach the first level, you will find the next Conch.
14: After the previous Conch is acquired, climb to the very top of this ridge. The final day one Conch will be waiting.
All Day 2 Phantasmal Conch locations
The 14th Conch is hidden inside the Misty Hills. Foggy Vales quest domain. You must complete the second Summertime Odyssey quest to unlock this new area. The Conch is located in the third area of this location. If you miss it during the story quest, you can revisit this zone via the Bonsai Tree you interact with to begin the search.
15: This hidden Conch is near the beginning of the third and final dojo. Drop down after the entrance of the first chamber to find it resting on a table.
All Day 3 Phantasmal Conch locations
16: The next Phantasmal Conches are located in Xinyan’s Domain. You must start and complete the Summertime Odyssey Blazin’ Trails quest event to access this domain. Once you have completed the domain, head back to the quest starting location located north of the Broken Isle. Access the drum and choose the Blazin’ Trails mission to enter the quest area a second time.
Once inside this realm, search for a door to enter that will take you to a puzzle area filled with chests and enemies to fight. Navigate through this domain until you reach a clearing with several horns and a puzzle chest. Once you open the chest, use the horns again to create a wind tunnel that will lift you to a nearby cliff.
Once you activate the lift and ride to the cliff, the 16th Phantasmal Conch will sit on the rock, as pictured below.
17: To reach this Conch, you must interact with the drums that allow you to enter Xinyan’s domain. These drums will enable you to change the style of the Broken Isle mountains. Change the mountains until the mountain on the right is very small.
Head towards the small mountain, which will now have a cave facing your approach. For the next section, you will need a Pyro character. Amber is a safe bet as all players have access to her. Inside the cave, you must light all the torches inside with fire. The first four torches will allow you to use a fire totem and enter the next chamber full of water.
In the next chamber, light up three of the torches and enter the door at the opposite end of the cave to find the fourth. Come back through the door, and the second fire totem will drain the water inside the chamber. The 17th Phantasmal Conch will be resting on top of a lantern.
Once you have at least 16 of the 20 Conches, you can acquire Fischl’s new costume from the Resonating Visions event page.
All Day 4 Phantasmal Conch locations
The fourth day of the Summertime Odyssey event brings the fourth quest to partake in, the Immernachtreich Apokalypse. This quest will contain the 18th Conch and change the open world, making the 19th Conch obtainable.
18: This Conch can be found inside Fischl’s domain world. Begin the quest and follow each step until you’re inside Fischl’s castle. The actual Conch is easy to find, as it’s resting on a table along the main path you must take to clear the stage. Near the beginning of this quest, keep an eye out for a courtyard with several tables. The Conch will be resting on one of them in plain sight.
19: Once you fully complete the Immernachtreich Apokalypse questline, the Twinning Isle portion of the Golden Archipelago region will be altered. New puzzles and dungeons will now reside here, alongside the next Conch. Head to the spot shown in the map below.
Once you reach this area, you will find three statues facing a small well in a circle. Speak with each statue to unlock an option to throw a stone into the well. Choose to throw a stone and pick from any three rocks you have in your inventory. Once this is done, the water will rise, and the 19th Conch will float on the surface.
This only leaves one final Phantasmal Conch left to be discovered in the Summertime Odyssey event, which will require one final domain to get through first.
All Day 5 Phantasmal Conch locations
The 20th and final Phantasmal Conch is located inside of Mona’s domain. This dungeon can only be accessed after completing the Summertime Odyssey V event quest, The Ancient Azure Stars. Once this quest is complete, you can enter the domain once again and choose the Temple of Star Latitudes to find the final Conch.
Once inside the region, head for the chamber marked with the constellation pictured below.
Once inside this chamber, complete the three puzzles located inside to summon a secret chest. To the right of the chest, you can walk up to the wall and touch it to open a secret room. This room will contain the 20th Phantasmal Conch.
With all 20 in your possession, you can claim all of the Resonating Visions event page rewards, which include a handful of Primogems and Fischl’s new costume. These rewards will remain in the game until the end of the Summertime Odyssey event, which will run until the end of version 2.8 for Genshin Impact.
