The Onirifalx Rod, sometimes called the RDX Rod, is a powerful endgame rod in Fisch designed to help you master high-tier fish faster than ever. But to get the most out of it, you’ll need to pair it with the right enchant — and the top choice is without question Song of the Deep.
Why Song of the Deep Is the Best Enchant for Mastery Grinding
Song of the Deep is one of the highest-tier enchants available in Fisch and is specifically designed to accelerate progress speed, which directly affects how fast you can catch fish.
Base Effect:
- +40% Progress Speed
With Onirifalx Rod Synergy:
The rod itself gives +70% progress speed on most fish types (excluding Apex/Event)
When combined with Song of the Deep, this totals:
+110% Progress Speed on most fish
This effectively halves the time it takes to catch each fish, making it perfect for:
- Mastery grinding
- Fishing for money
- Collecting materials at high volume
How to Get Song of the Deep
Step 1: Acquire a Movie
Song of the Deep comes from Movie-type items
These are crafted or acquired through special drops or trade-ins
Step 2: Appraise It
Visit the Appraisal NPC to reveal its enchant
If it doesn’t show Song of the Deep, you’ll need to use another movie or reroll
As of the latest update, the chance of getting Song of the Deep has been buffed, making it easier to obtain on your first or second try.
How to Equip Song of the Deep to Onirifalx Rod
Once you’ve appraised a movie and confirmed it has Song of the Deep:
- Head to the Enchant Station
- Select your Onirifalx Rod
- Apply the enchant from your movie
- Confirm and lock it in
Note: You can use a lower-value movie (like Sandy) if you want to save rare ones for other rods.
Testing Results (Based on Player Experience)
A player ran a test using Song of the Deep with Onirifalx Rod at Castaway Glyphs, one of the best money-making zones in the game.
Results:
- Over 20 minutes of fishing:
- High-volume catches
- 110% progress speed drastically reduced catch time
- Excellent synergy with piercing passives (example: +1% progress per fish type)
- High profit margins
You’ll also notice a massive increase in fish per minute, which directly helps with Mastery unlocks for rare fish.
Bonus Enchant Synergy Tip
If you can combine Song of the Deep with Piercing or Lure Speed secondary enchants, you’ll further optimize your catch cycle. Focus on enchants that:
- Increase progress
- Reduce resistance
- Boost hook or lure rate
