Fisch has 10 Sky Crystals tied to the Keeper's Questline, but they are spread across different islands and use several collection methods. Some are simple pickups, while others require fishing, an NPC request, a C$500,000 payment, a meteor gem, or enough Ancient Idol progress.
Use the table to jump straight to a missing crystal, then follow its route for the exact landmark and collection action. The reported Ancient Idol levels are included as planning markers, and the Mountain Crystal requirement is flagged because current reports disagree.
All 10 Fisch Sky Crystal Locations at a Glance
| Sky Crystal | Where to look | How to collect it | Ancient Idol level |
|---|---|---|---|
| Lighthouse | Moosewood lighthouse, below the top glass window | Climb up and interact with the crystal | 0 |
| Aquatic | Terrapin Island, Otter Companion spot | Fish for the secondary catch | 3 |
| Campfire | Roslit Bay campfire and Ashe | Bring an Albino Mutated Skycrest fish with a Noir rod | 5 |
| Icy | Snowcap Pond and the lower secret cave | Retrieve the Lost Rod and return it to Wilson | 8 |
| Skull | Forsaken Shores and Jack Marrow | Pay C$500,000 | 12 |
| Living | Lost Jungle, Forgotten Temple, Mossjaw Rest | Reach the Pedestal room and interact with the green-vine crystal | 15 |
| Mountain | Broken ship beside Castaway Cliffs | Climb up and check beside the large stool | 17* |
| Prismatic | Ancient Isle and the Meteoriticist | Give the NPC one Opal, Moonstone, or Lapis Lazuli | 30 |
| Divine | Glacial Grotto cave near Heaven's Rod | Enter the secret cave and interact with the corner crystal | 40 |
| Infernal | Scoria Mineshaft, across the central lava | Cross the mine and check beside the pillar | 50 |
Use the levels in the last column as planning markers for each route. Mountain has the only reported disagreement: one current guide puts the requirement at Level 17, while another puts it at Level 20. If the pickup is locked at 17, follow the Ancient Idol prompt in your game and plan around the higher reported threshold.
How to Get Each Sky Crystal in Fisch
How to Get the Lighthouse Sky Crystal in Fisch
Go to the back side of Moosewood and enter the lighthouse. Climb to the top, then look below the glass window panel for the Sky Crystal and interact with it. The spot is around (686, 252, 318), but the lighthouse top and window are the more useful landmarks.
How to Get the Aquatic Sky Crystal in Fisch
Travel to the Otter Companion location on Terrapin Island and fish at about (-103, 130, 1891). Keep fishing until the secondary catch is the Aquatic Sky Crystal. This catch is reported at 1/10 rarity, so treat that as a chance rather than a guarantee after ten casts.
How to Get the Campfire Sky Crystal in Fisch
Speak with Ashe at the Roslit Bay campfire, around (-1708, 148, 734). She asks for an Albino Mutated fish from Skycrest Island. Take any rod with the Noir Enchantment to Skycrest, fish until you obtain the requested fish, and return it to Ashe. The crystal comes from that turn-in, not from a separate pickup around the campfire.
How to Get the Icy Sky Crystal in Fisch
Find Wilson at Snowcap Pond, around (2929, 281, 2572). Go down the ledge into the lower area and secret cave, where the Lost Rod is around (2887, 138, 2716). Pick up the Lost Rod, then return it to Wilson to receive the Icy Sky Crystal.
How to Get the Skull Sky Crystal in Fisch
At Forsaken Shores, find Jack Marrow around (-2824, 214, 1516) and pay him C$500,000. The crystal is awarded through that payment, so you do not need to search the island for a separate pickup.
How to Get the Living Sky Crystal in Fisch
Reach Lost Jungle and use the rope near (-2589, 158, -2194) to enter the Forgotten Temple. If Mossjaw Rest is still closed, complete the access route first: you need the Temple Eye, the five room/rune solutions, and the five glyphs placed at their pedestals. Then continue to the Mossjaw Rest Pedestal room, around (-5120, -1760, -10165), and interact with the crystal floating on a green vine.
How to Get the Mountain Sky Crystal in Fisch
Go to the broken ship beside Castaway Cliffs, around (347, 130, -2323). Climb onto the ship and look beside the large stool for the Mountain Sky Crystal.
One current guide puts the Mountain pickup at Ancient Idol Level 17, while another reports Level 20. If it is not available at 17, use the in-game Ancient Idol requirement as your checkpoint and try again at the higher reported level instead of treating the coordinates as wrong.
How to Get the Prismatic Sky Crystal in Fisch
Speak with the Meteoriticist on Ancient Isle, around (5919, 262, 583). Bring one Opal, Moonstone, or Lapis Lazuli from a Meteor, then give it to the NPC. Any one of those named gems satisfies the resource step.
How to Get the Divine Sky Crystal in Fisch
Climb Northern Expedition to Glacial Grotto at the top near Camp 4, then enter the secret cave. Look in the corner near Heaven's Rod and interact with the Divine Sky Crystal.
How to Get the Infernal Sky Crystal in Fisch
Enter Scoria Mineshaft around (-4976, 145, -1577) and go underneath the mineshaft. Cross the lava at the center, then look beside the pillar around (-4709, -697, -2054). Interact with the crystal at that spot to collect Infernal.
Access Notes for the Harder Crystal Routes
How to Reach Skycrest from Moosewood
From Moosewood, use the pink-clam teleporter to Fischfest 2. Take a boat to the back waterfall at about (-25700, 2591, -4712), then swim upward to reach Skycrest.
Preparing for Glacial Grotto
Prepare oxygen and thermal protection before making the climb to Camp 4.
After You Collect All 10 Fisch Sky Crystals
After the final pickup, return to the active Keeper objective and follow the in-game prompt. Sources disagree about the exact crystal count tied to early chamber or door progression, so use the live objective instead of relying on a fixed number or assuming a particular reward. The useful checkpoint covered here is the full set of 10 crystals; let the live objective tell you what comes next.
