As a dedicated Fish It player who’s spent countless hours exploring every corner of this Roblox sensation, I’m excited to share my complete walkthrough on how to get the pickaxe for the Crystalized Mutation. The Crystal Depths update has completely transformed the endgame experience, and trust me, this pickaxe is absolutely essential for maximizing your fishing potential in the new underwater paradise.
The Crystal Depths update, released on January 18, 2026, represents Fish It’s most ambitious content expansion yet. This underwater wonderland introduces two exclusive sublocations: the Crystal Depths and the Leviathan Den. What makes this update particularly special is the introduction of the Crystalized Mutation – a game-changing modifier that can significantly boost the value of your catches.
I’ve been playing since the early days, and I can tell you that this update rivals the excitement of the Adopt Me Halloween events in terms of content depth. The Crystal Depths area is only accessible with the Advanced Diving Gear, making it true endgame content that separates the casual players from the dedicated anglers.
There’s something magical about descending 200 meters below the surface and discovering an entirely new ecosystem teeming with rare fish and glowing crystals. The atmosphere reminds me of exploring Monster Hunter’s most stunning environments, but with that unique Roblox charm that keeps me coming back.
What really gets me excited is the thrill of mining those glowing crystals. Each successful mining session feels like opening a rare SNES game cartridge – you never know what treasure you’ll uncover. The Crystalized Mutation has completely changed how I approach fishing, turning every cast into a potential jackpot moment.
Before you can even think about getting a pickaxe, you’ll need to reach the Crystal Depths. Here’s what I learned from my experience:
First, head to Pirate Cove island and make your way to the dock area. You’ll need to purchase the Advanced Diving Gear for a whopping 1 million gold coins. I know what you’re thinking – that’s a lot of cash! My advice? Focus on AFK fishing with your best rod and sell everything you catch. It took me about 3-4 days of dedicated grinding to afford it.
The Advanced Diving Gear is located near the pond area in Pirate Cove – look for the red-colored equipment on a wooden crate. Once you’ve bought it, equip the gear and interact with the special diving spot in the middle of the circular pathway. You’ll descend in two stages (100 meters each) until you reach the Crystal Depths.
Once you’re in the Crystal Depths, swim to the right side to find Hank NPC standing near a massive crystal. He’s the key to getting your pickaxe, but be prepared for a challenging quest.
Hank will tell you about his mysterious diary that he lost in the waters nearby. This isn’t just any ordinary fetch quest – the diary is incredibly rare with a 1 in 50,000 catch rate. I spent nearly 2 hours fishing for it, so patience is definitely required here.
This is where most players get stuck, and I have some pro tips that will save you hours of frustration:
Location matters: Fish in the pond area right next to Hank. Don’t waste time in other parts of Crystal Depths – the diary only spawns in this specific spot.
Use your best rod: I recommend using the Element Rod or Diamond Rod if you have them. The better your rod, the higher your chances of catching the diary.
Luck boosters are your friend: Use any Luck II Potions you have saved up. They significantly increase your chances of catching rare items.
Time your fishing: I found that fishing during server peak times (when more players are online) seems to increase spawn rates for rare items.
Here’s the most important tip that I learned the hard way: you must hold the diary in your hand when talking to Hank. If the diary is just sitting in your inventory, he won’t recognize it and won’t give you the pickaxe.
I made this mistake myself and wasted an hour wondering why Hank wouldn’t accept my diary. Here’s exactly what to do:
Once you do this correctly, Hank will reward you with the pickaxe, and you’re ready to start mining crystals!
Now for the fun part! With your new pickaxe equipped, explore the Crystal Depths and look for glowing crystals. Not all crystals are active at the same time – you can only mine the ones that are glowing with a blue light.
When you find a glowing crystal, get close and press E (on PC) or the interact button (on mobile) to mine it. You’ll receive Cave Crystals, which work like potions that boost your chances of getting the Crystalized Mutation when fishing.
The Crystalized Mutation is incredibly valuable – it can turn a common fish into something worth thousands of coins. I’ve seen fish values increase by 500% or more with this mutation!
Before attempting the Crystal Depths quest, I recommend building up your coin stash. Here’s my proven method:
Once you have the pickaxe, create a crystal farming route:
Based on my experience helping other players, here are the most common mistakes:
While you’re in Crystal Depths, don’t forget to complete Dorian’s quest for the Coral Lantern skin. He wants you to collect 30 coral reefs from around the underwater zone.
Coral reefs spawn in three main areas:
They respawn after about 10 minutes, so you can collect 7-10 corals per dive. The Coral Lantern is purely cosmetic, but it looks amazing and shows off your Crystal Depths mastery!
The Crystal Depths update is scheduled to end on January 25, 2026, so make sure to complete all quests before then. Based on the update pattern, Fish It typically releases new content every Sunday, so we can expect another major update soon.
The next update is rumored to introduce even more underwater areas and possibly new mutation types. I’m particularly excited about the potential for new customization options similar to what we’ve seen in other Roblox games.
A: It varies, but expect 3-6 hours total – 1-2 hours to earn 1 million coins, and 1-4 hours to fish for Hank’s diary.
A: No, the Crystal Depths is only accessible with the Advanced Diving Gear, which is required to start Hank’s quest.
A: Absolutely! I’ve seen fish values increase by 500-1000% with this mutation. It’s a game-changer for endgame players.
A: Yes, crystals work like potions with a timed effect. Use them within a few hours of mining for best results.
A: No, the pickaxe is a personal quest reward and cannot be traded.
Getting the pickaxe for Crystalized Mutation in Fish It is definitely worth the effort. The journey from saving up 1 million coins to finally mining your first glowing crystal is an incredibly rewarding experience that showcases everything great about this game.
I hope my guide helps you avoid the mistakes I made and speeds up your progress. The Crystal Depths represents some of the best content Fish It has to offer, and with this pickaxe in hand, you’re ready to take full advantage of everything this underwater paradise has to offer.
Happy fishing, and may your catches be ever mutated! Drop me a comment below if you have any questions or want to share your own Crystal Depths experiences.
