What Is Ruby Mutated Gemstone in Fish It?
The Ruby Mutated Gemstone has become one of the most sought-after items in Fish It Roblox since the latest update. This isn’t just any regular Ruby – it’s a special version that’s absolutely crucial for your progression. Let me break down exactly what makes this item so special:
Key Characteristics:
- Legendary Status: Ruby is classified as a Legendary item, making it quite rare to begin with
- Mutation Requirement: The Diamond Researcher (Larry) will ONLY accept the Mutated version
- Quest Critical: Essential for completing the Diamond Rod quest line
- Visual Difference: While it looks similar to a normal Ruby, the “Mutated” status appears in its description
Many players make the critical mistake of catching a regular Ruby and rushing to the quest NPC, only to be disappointed. I’ve seen this happen countless times, and it’s one of the most frustrating setbacks in the game. The key difference is that mutated version – without it, you’re stuck.
Complete Diamond Rod Quest Requirements
Before diving deep into Ruby hunting, let me give you the full picture of what the Diamond Rod quest entails. This will help you understand why the Ruby Mutated Gemstone is so crucial and plan your overall strategy:
All Requirements for Diamond Rod:
- Own all four Elemental Rods – You’ll need to complete previous quest lines first
- Catch Secret Fish at Coral Reefs – Two different Secret Fish spawn here
- Catch Secret Fish at Tropical Grove – One Secret Fish available in this location
- Bring Ruby Mutated Gemstone – The main focus of this guide
- Bring Lochness Monster – Found at Kohana Island (volcano island)
- Catch 1,000 fish with Perfect Throw – This takes time and practice
As you can see, the Ruby Mutated Gemstone is just one piece of a larger puzzle, but it’s often the bottleneck that stops players from progressing. That’s why I’ve created this comprehensive guide specifically for this challenging part of the quest.

Mutation Mechanics: How to Get Ruby Mutated Gemstone
This is where most players get stuck. You can catch a regular Ruby all day long, but without the “Mutated” status, it’s useless for the Diamond Rod quest. Let me break down exactly how mutations work and how to maximize your chances:
Understanding Mutation Basics
Mutations in Fish It work through a combination of luck, timing, and special items. When you catch a Ruby, there’s a chance it will spawn as mutated. However, you can significantly increase these chances through several methods:
Method 1: Mutation Potion (Most Reliable)
This is by far the most consistent method I’ve found for getting mutated fish:
How to Use Mutation Potion Effectively:
- Activate the potion BEFORE you start fishing
- Do NOT change maps or locations while the potion is active
- Fish continuously until the potion duration expires
- Stack with other mutation-boosting items for maximum effect
Where to Get Mutation Potions:
- Check the daily shop rotation
- Participate in special events
- Use Fish It codes (check our Fish It Codes guide for current working codes)
Method 2: Mutation Hunter Enchantments
Your rod enchantments play a huge role in mutation rates:
- Mutation Hunter I: +10% mutation chance
- Mutation Hunter II: +30% mutation chance (recommended)
How to Get These Enchantments:
- Save up Legendary Enchant Stones
- Focus on upgrading your rod with mutation-specific enchants first
- Consider this a long-term investment for your fishing career
Method 3: Special Baits and Bobbers
Certain items dramatically increase your mutation chances:
- Aether Bait: +20% mutation chance
- Royal Bait: Increases mutation-chance stat
- Mutation-specific bobbers: Check the shop for rotating stock
Method 4: Admin Events (Game-Changer)
This is where you can get massive mutation boosts:
- Super Mutated Events: 5× mutation rate boost
- Meteor Rain Events: May grant mutation multipliers
- Special Holiday Events: Often include mutation bonuses
How to Stay Updated:
- Join the official Fish It Discord server
- Follow the game’s Twitter/X account
- Check in-game blackboards for event announcements
- Set up notifications for admin events

Advanced Tips and Pro Strategies
After helping dozens of players complete this quest, I’ve discovered some advanced strategies that most guides miss:
Inventory Management Hacks
- Keep 10-15 slots free at all times during mutation hunting
- Sell common fish immediately to avoid inventory full situations
- Prioritize keeping mutated fish over regular legendary catches
- Use backpack upgrades early to maximize fishing time
Location Rotation Strategy
Instead of staying in one spot, try this rotation pattern:
- Tropical Grove (30 minutes)
- Lost Isle Treasure Room (30 minutes)
- Ocean hotspot (30 minutes)
- Repeat cycle
This prevents burnout and maximizes your exposure to different spawn pools.
Community Coordination Tips
- Join fishing groups during mutation events
- Share information about active events
- Coordinate with friends to cover multiple locations
- Trade tips about recent spawn patterns
Common Mistakes to Avoid
I’ve seen so many players make these same mistakes. Learn from their experience:
Critical Errors:
- Not checking for “Mutated” status before turning in to NPC
- Changing locations during Mutation Potion duration
- Ignoring admin events and missing 5× mutation boosts
- Using wrong enchantments that don’t boost mutation rate
- Poor inventory management causing missed fishing opportunities
Time-Wasting Habits:
- Fishing in wrong locations (rivers, land spots won’t spawn Ruby)
- Not preparing adequately before long fishing sessions
- Giving up too early – Ruby can take time to spawn
- Not using mutation-boosting items to maximize chances
Equipment Recommendations
Based on my extensive testing, here’s what I recommend for optimal Ruby hunting:
Best Rod Setup:
- Primary: High luck rod with Mutation Hunter II enchant
- Secondary: Speed-focused rod for quick casting during events
- Backup: Basic rod for emergency situations
Essential Items:
- Mutation Potions: Always have 3-5 in inventory
- Aether/Royal Bait: Stack with potions for maximum effect
- Luck Potions: Use during non-mutation focused fishing
- Backpack Upgrades: Minimum 30 slots recommended
Troubleshooting Guide
Still Not Getting Ruby Mutated Gemstone?
If you’ve been following this guide and still struggling, try these troubleshooting steps:
- Verify Your Location: Are you definitely in Ocean areas or the specific locations mentioned?
- Check Your Buffs: Are all potions and enchantments active?
- Event Timing: Are you missing optimal fishing windows?
- Server Issues: Try switching servers if spawn rates seem unusually low
- Update Check: Ensure you’re on the latest game version
When to Take a Break?
Sometimes the RNG just isn’t in your favor. Consider taking a break if:
- You’ve been fishing for 3+ hours without any Ruby spawns
- You’re feeling frustrated and making mistakes
- No admin events have occurred recently
- You’re running low on resources
Frequently Asked Questions
How long does it typically take to get Ruby Mutated Gemstone?
Based on community data and my own experience, most players get it within 2-6 hours of focused fishing with proper preparation. However, this can vary significantly based on luck and event timing.
Can I get Ruby Mutated Gemstone without Mutation Potion?
Yes, but it’s much harder. Your base mutation chance is quite low without boosts. I’ve seen players get lucky, but it’s not reliable for quest progression.
What’s the best time of day to fish for Ruby?
Admin events don’t follow a specific schedule, but evenings and weekends tend to have more events. The key is being available when events happen rather than fishing at specific times.
Should I sell regular Ruby gems?
No! Keep them in case you need them for future content. Only sell if you’re desperate for inventory space and have already completed the Diamond Rod quest.
Can I trade for Ruby Mutated Gemstone?
Currently, there’s no trading system in Fish It. You’ll need to catch it yourself.
Final Thoughts
Getting the Ruby Mutated Gemstone is definitely challenging, but with the right strategy, preparation, and a bit of patience, you’ll get there! The key is understanding that this isn’t just about luck – it’s about systematic preparation and maximizing your chances during optimal conditions.
Remember to save this guide and check back regularly, as I update it with new strategies and information as the game evolves. The Diamond Rod is worth the effort, and you’ll be glad you put in the work once you’re reeling in those legendary catches with your new endgame rod.
Happy fishing, and may the mutation odds be ever in your favor! 🎣
