Fastest Method to Unlock ASTRAEUS Passive March 2026
Based on extensive testing and community feedback, the Banana fish farming during Aurora method is currently the fastest way to complete Challenge 3 and unlock the ASTRAEUS passive in just 1-2 hours.
Why Banana Fish Are Optimal?
| Factor | Banana Fish | Alternative Methods |
|---|---|---|
| Spawn Rate | Very high during Aurora | Low for dragons/leviathans |
| Catch Cycle | Fast (3-4 minutes) | Slow (10-15 minutes) |
| Risk Level | Low | High (boss fish can escape) |
| Mutation Efficiency | 15% Astraeus chance | Same chance but fewer attempts |
| Overall Time | 1-2 hours | 4-6+ hours |

FAQ
How long does it really take to unlock ASTRAEUS passive?
With the optimal Banana farming method during Aurora, using Gobstopper + Hasty + Luck Potions, most players complete it in 1–2 hours. Without the optimal setup, it can take 4–6+ hours.
Do I need to keep the Astraeus Serenade rod equipped?
Yes. All mastery progress only counts when you are actively using the Astraeus Serenade rod. Catches made with other rods do not contribute.
What’s the best time to attempt this unlock?
During Aurora events, preferably while Luck Potions are active. Weekends often provide better server performance and more frequent Aurora cycles.
Can I complete challenges in any order?
Yes, the three mastery challenges can be completed in any order, but Challenge 3 (Astra Divinity) requires the most grinding and preparation.
Is the ASTRAEUS passive worth the effort?
Absolutely. The Firefly Entity passive provides major advantages for late-game content, making it one of the most valuable upgrades in 2026.
What happens if I lose connection during a perfect catch?
Unfortunately, that progress does not count. Make sure you have a stable internet connection and consider using less populated servers for reliability.
Common Issues & Solutions

Problem: Not getting Astraeus mutations Solution: Ensure you’re using Gobstopper bait, focus on perfect catches, check that you have the Astraeus Serenade equipped
Problem: Progress seems slow Solution: Double-check your setup (Hasty enchant, Luck Potion), consider server hopping for better Aurora conditions
