Fish It is a popular Roblox experience where you go fishing, explore the seas, and collect all sorts of fish. You need to travel between islands to unlock new fish, use bait and rods, and try to catch the rarest fish you can.
In the latest Crystal Depths update, you can get the Legendary Leviathan which has a rarity of 1 in 5 million. So, here’s a complete guide on how to get Leviathan in Fish It.
How To Get Leviathan In Fish It

Buy The Advanced Diving Gear
First, you need to collect 1 million gold to buy the Advanced Diving Gear from the Pirate Cove Island. This special gear lets you reach depths that basic equipment cannot reach.
You should travel to the right side of Fisherman Island, enter Pirate Cove, head to the back area, and purchase the item. After equipping the gear, you need to break the cave by placing the four TNTs the Carpenter NPC requests.
After the explosion clears the path, you can dive into the water and begin descending nearly 200 meters. You will reach the Secret Passage, where the Leviathan questline officially starts.
Talk To The Archeologist NPC
After you reach the Secret Passage, you will meet a new NPC called the Archeologist. He will assign you a fresh quest that you need to complete before entering the Leviathan’s Den. You have to finish this task to begin the Leviathan Hunt. Below are the quests and required items:
| Item Name | How to Get | Purpose |
|---|---|---|
| Leviathan Scale | Daily quest reward | Activates the Leviathan Hunt event |
| Ocean Core | Found at the quest location | Powers the cave entrance |
| Leviathan Essence | Quest completion reward | Unlocks the Leviathan’s Den cave door |
The Leviathan Scale is the most important item for this hunt. You can only obtain one each day from the Crystal Depths daily quest, so you have to wait 24 hours between attempts.
Complete The Forgotten Scale Quest
After you get the Leviathan Scale, you need to collect three relics for the Forgotten Scale Quest from the Archeologist NPC. These relics below spawn across different islands, so you should prepare for exploration:
| Relic Name | Location |
|---|---|
| Burntflame Relic | Crater Island |
| Sunken Eye Relic | Tropical Grove |
| Blacktide Relic | Lost Isle |
These relics are easy to locate as you will see arrows on your screen after you reach each island, pointing directly to every stone. You need to collect all three stones quickly since others can beat you to it.
You can work with others as well during a single Leviathan hunt. So, you can split tasks by sending one to Lost Isle while another heads to Tropical Island. This strategy will speed up relic collection.
Open Leviathan’s Den in Fish It

After you have all three relics, you need to return to the Archeologist NPC in the Secret Passage. You need to talk to him and turn in the three relics along with your Leviathan Scale. After the hand-in is complete, the cave door opens automatically for you.
Here is an important detail you should remember before starting the quest. Only one player has to complete the turn-in to open the cave for the entire server. You can coordinate with friends to save time. After the door opens, everyone nearby can enter and start fishing for Leviathan together.
Catch The Leviathan
Inside the den, you need to cast your fishing rod into the special fishing spot. Leviathan has a rare 1 in 5 million catch rate, so you can end up spending hours fishing without success.
You should bring your strongest fishing setup before entering the cave. Use your best rod, equip the top bobber, activate luck-boosting fish fry items, and apply a solid enchantment.
