Understanding Hank’s Diary: The Ultimate Quest Item
Hank’s Diary represents one of Fish It’s most challenging yet rewarding quests. This Mythical rarity item isn’t just another catch—it’s your gateway to the Crystal Depths’ most valuable resources. The diary serves as the exclusive key to unlocking Hank’s Pickaxe, an essential tool for farming Cave Crystals that boost your Crystalized Mutation chances.
Contents
What makes this quest particularly challenging is the extreme rarity combined with specific requirements that many players overlook. Unlike standard fish, the diary won’t appear in your catches unless you’ve properly triggered Hank’s quest dialogue and are fishing in the exact right location. This attention to detail separates successful players from those who waste hours fishing in wrong spots.
The diary’s Mythical status places it among the game’s rarest items, with only Secret-rarity fish like the Cursed Kraken (1 in 3,500,000) and Leviathan being more difficult to obtain. However, unlike those near-impossible catches, Hank’s Diary is achievable with the right strategy, patience, and understanding of the game mechanics.
Preparing for the Crystal Depths Expedition
Advanced Diving Gear: Your Essential Investment
Before attempting to find Hank’s Diary, you must secure the Advanced Diving Gear—the red-colored equipment that distinguishes serious players from casual anglers. This isn’t your basic yellow Diving Gear; it’s a premium endgame item that unlocks the Crystal Depths’ secrets.
Location Details:
- Found above a small wooden crate on Pirate Cove island
- Close to the circular pathway in the middle of the dock area
- Walk past the regular fishing spot to the back area
- Look for the entirely red gear (not yellow like basic diving equipment)
Cost Analysis: At 1,000,000 Coins, this represents one of the game’s most significant investments. Many mid-game players face the dilemma of choosing between better fishing rods (Astral or Hazmat) or the diving gear. Pro tip: Invest in a better rod first—it’ll significantly increase your chances of catching the diary and other rare Crystal Depths fish.
Technical Specifications:
- Allows diving to 200 meters below surface
- Required for Crystal Depths access via the special diving boat
- One-time purchase with permanent use
- Can be gifted between players (though rarely done due to cost)
Optimal Rod Selection for Diary Hunting
Your choice of fishing rod dramatically impacts your diary hunting success. While any rod can technically catch the diary, luck-boosting equipment significantly reduces your grinding time.
Recommended Rods (in order of preference):
- Element Rod – Highest luck stats for rare catches
- Diamond Rod – Excellent balance of luck and power
- Astral Rod – Good mid-to-late game option
- Hazmat Rod – Decent alternative if others unavailable
Rod Strategy: The diary is fundamentally a “drop” rather than a standard fish, meaning your rod’s Luck stat directly influences your catch rate. Combine this with Perfect/Great catches to maximize your hourly efficiency. Active fishing (not AFK) ensures you don’t miss the crucial moment when the diary finally appears.
Step-by-Step Guide: Finding Hank’s Diary
Step 1: Accessing the Crystal Depths
Once equipped with your Advanced Diving Gear, head to the Pirate Cove dock area. Look for the special boat in the middle of the lake—you’ll notice a “Descend” option when approaching the long pole next to it.
Access Process:
- Equip your Advanced Diving Gear from the hotbar
- Navigate to the circular pathway in Pirate Cove’s center
- Find the boat with the descending pole
- Press E (PC) or interact button (mobile) to descend
- Experience two 100-meter descents totaling 200 meters depth
Environmental Features: The Crystal Depths features glowing crystals, darker waters, and unique underwater architecture. You’ll immediately notice the difference from standard fishing areas—the atmosphere alone signals you’ve entered endgame territory.
Step 2: Locating and Triggering Hank’s Quest
This is where most players fail. Hank isn’t just an NPC—he’s a quest trigger that must be activated before the diary enters the loot pool.
Finding Hank:
- Located on the right side of the Crystal Depths area
- Standing on a ledge or near a rope
- Opposite direction from Dorian (another questgiver)
- Near a massive Crystal formation
CRITICAL Quest Trigger:
⚠️ DO NOT START FISHING IMMEDIATELY!
You MUST talk to Hank first and listen to his dialogue about losing his diary. This interaction is essential—without it, the diary won’t appear in your catches regardless of how long you fish.
Dialogue Details: Hank will mention losing his diary and ask for your help in finding it. Only after this conversation does the game add the diary to your potential catches in the Crystal Depths area.
Step 3: The Grind – Fishing Strategy and Optimization
With the quest triggered, position yourself strategically for maximum efficiency.
Optimal Fishing Position:
- Stand as close to Hank as possible
- Cast your line into the Crystal Depths water nearby
- Stay within the Crystal Depths biome (leaving resets your progress)
- Face the general direction of deeper waters
Fishing Technique:
- Use your best luck-boosting rod
- Aim for “Perfect” or “Great” catches consistently
- Maintain active fishing (don’t go AFK)
- Watch for the diary notification carefully
- Don’t switch servers or locations during the grind
Time Management: Based on player reports and the 1 in 50,000 catch rate, expect 1-5 hours of continuous fishing. This varies significantly based on:
- Your rod’s Luck stat
- Catch quality (Perfect > Great > Good > OK)
- RNG factors inherent to the game
- Server performance and lag
Step 4: The Crucial Turn-In – Most Common Mistake
This step eliminates 90% of failed attempts. Many players catch the diary but can’t complete the quest because of one critical error.
THE ABSOLUTE REQUIREMENT:
You MUST equip the diary in your hand when talking to Hank.
If the diary is merely in your inventory but not actively held, Hank won’t recognize it and won’t give you the Pickaxe.
Correct Turn-In Process:
- Catch the diary (it appears in your inventory)
- Open your inventory and equip the diary like a tool
- Walk back to Hank while holding the diary
- Talk to him with the diary still equipped
- Receive your Pickaxe reward
Troubleshooting: If Hank doesn’t give you the Pickaxe:
- Double-check that you’re actually holding the diary
- Ensure you completed the initial quest dialogue
- Verify you’re in the Crystal Depths area
- Try re-equipping the diary and talking again

Technical Questions
