Players can obtain the 10 Sky Crystals from Islands like Moosewood, Roslit Bay, Forsaken Shores, Lost Jungle, Scoria Reach, Snowcap Island, Castaway Cliffs, and Terrapin Island by performing some sort of quest associated with them.
As part of the Keeper's Questline, you are supposed to find 10 different Sky Crystals across various locations on Fisch Island. While a few are easy to locate, others require an intensive search. So, if you have found a few Sky Crystals and are looking for the rest, here is a detailed guide.
Where are the 10 Sky Crystals located in Fisch?
Below, you can find all 10 Sky Crystal locations in Fisch & the fastest way to reach each of them. I've also included the Ancient Idol Level requirement to collect each Crystal.
Lighthouse Sky Crystal - Moosewood (Ancient Idol Level 0)
The first one is located on Moosewood Island. After reaching the island, go towards the back side to find the lighthouse. Enter and climb the stairs to reach the top, where you can find the Sky Crystal at GPS (686, 252, 318) underneath a glass window panel.
Aquatic Sky Crystal -Terrapin Island (Ancient Idol Level 3)
To get the Aquatic Sky Crystal, you must travel to Terrapin Island. Here, fish at the location where you would get the Otter Companion at GPS (-103, 130, 1891). This is a secondary catch with 1/10 rarity. So, keep fishing at the location until you get one.
Campfire Sky Crystal - Roslit Bay (Ancient Idol Level 5)
For the next one, travel to Roslit Bay and speak to the Ashe NPC standing in front of a campfire at GPS (-1708, 148, 734). Speak with him, and he will ask you to get an Albino Mutated fish from Skycrest Island. So, use any Rod with the Noir Enchantment and fish until you get one. Return any such fish to get the Campfire Sky Crystal.
Icy Sky Crystal - Snowcap (Ancient Idol Level 8)
This one is at Snowcap Island. After reaching the island, slowly make your way to the top until you locate the Wilson NPC standing adjacent to the Snowcap Pond at GPS (2929, 281, 2572). Speak with the NPC, and he will ask you to find his Lost Rod. Jump down the ledge next to him to go to the bottom of Snowcap Island, which leads you to a secret cave at GPS (2887, 138, 2716) where you can find the Rod on the ground. Collect it and return to get the Sky Crystals.
Skull Sky Crystal - Forsaken Shores (Ancient Idol Level 12)
For the next one, you have to go to the Forsaken Shores and slowly make your way up the island until you find the Jack Marrow NPC at GPS (-2824, 214, 1516). Speak with him and pay C$500K to get the Skull Sky Crystal.
Living Sky Crystal - Lost Jungle (Ancient Idol Level 15)
This is another easy Sky Crystal to obtain in Fisch. First, head to Lost Jungle Island and reach the Forgotten Temple using the rope at GPS (-2589, 158, -2194). Inside the temple, go to the Mossjaw Rest Pedestal room at GPS (-5120, -1760, -10165) where you can find the Living Sky Crystal floating on top of a green vine. Interact with it to get the item.
Mountain Sky Crystal - Castaway Cliffs (Ancient Idol Level 17)
The Mountain Sky Crystal is present on the broken ship next to the Castaway Cliffs. Go to the broken ship at GPS (347, 130, -2323). Climb the ship to find the Mountain Sky Crystal next to the large stool. Ensure you have your Idol Level at least 17 to collect it.
Prismatic Sky Crystal - Ancient Isle (Ancient Idol Level 30)
This is another easy Sky Crystal to collect. Go to the Ancient Isle POI and meet the Meteoriticist at GPS (5919, 262, 583). Interact with him, and he will ask for Opal, Moonstone, or Lapis Lazuli in exchange for the Sky Crystal—all of these drop from Meteors that fall from the sky. So, if you already have one of these, give it to the NPC or explore the entire island for more Meteors that can give one of these.
Divine Sky Crystal - Northern Expedition (Ancient Idol Level 40)
The Divine Sky Crystal is located on the Northern Expedition. After landing, slowly make your way to the top until you reach the Glacial Grotto, the topmost part of the Island at Camp 4. Here, enter the secret cave to find Heaven's Rod at GPS (19,980, 916, 5384) and the Divine Sky Crystal in a corner.
Infernal Sky Crystal - Scoria Reach (Ancient Idol Level 50)
The last and final Infernal Sky Crystal is inside the Scoria Mineshaft. Go to the Scoria Reach and enter the Mineshaft at GPS (-4976, 145, -1577). Underneath the Scoria Mineshaft, cross the lava at the center to reach the other side and find the Infernal Sky Crystal at GPS (-4709, -697, -2054) next to a pillar.
What is the use of Sky Crystals in Fisch?
As mentioned earlier, Sky Crystals are part of the Keeper Questline. You must collect at least 5 of them to restore Abaia's Chamber, unlock the initial gate & wait for the awakening.
