How to fish in the Steal an Egg Alien biome
Update 12 adds fishing throughout the Alien biome, letting you collect new resources and exclusive rewards.
You can fish in the biome’s lakes or travel to the Alien Lagoon, a separate fishing area accessible through the Alien Ferryman.
How to get the Alien Rod
To start fishing, follow these steps:
- Enter the Alien biome.
- Find the Alien Ferryman NPC near the water.
- Talk to the Alien Ferryman to receive the Alien Rod.
NOTE: Alternatively, you can use the Ghost Fishing Rod obtained during the Halloween Dimension update.
Talk to the Alien Ferryman to obtain your Alien Rod.
Alien fishing rewards
Fishing in the Alien biome offers several rewards:
- Void Pearls: A new currency used to purchase Dark Matter mutation consumables.
- Alien eggs: Obtain eggs from the new biome.
- Abducted mutation: A chance to obtain the mutation introduced in update 11.
- Relics: Collect these items to unlock the new Fusion behind the Relic Gate.
Fishing also contributes toward the new Fishing Milestones, which reward players for their total catches.
How to reach the Alien Lagoon
The Alien Lagoon is a separate fishing area introduced in update 12. It is also where the new Nebuloth Kraken event takes place.
To reach the Alien Lagoon:
- Enter the Alien biome.
- Find the Alien Ferryman NPC.
- Talk to him and select the option to travel to the Alien Lagoon.
- Enter the Lagoon and start fishing.
NOTE: Unlike regular biomes, the Alien Lagoon doesn’t teleport you back to your base at night. This makes it an excellent location for uninterrupted fishing and progressing through Fishing Milestones.
The helpful Alien Ferryman offers travel to the lagoon free of charge
Cosmic Eclipse event in Steal an Egg
The Cosmic Eclipse is a new global fishing event that takes place inside the Alien Lagoon every 30 minutes at the 25- and 55-minute marks.
During the event, players across all Steal an Egg servers compete to catch the new Divine Nebuloth Kraken.
However, there’s a catch: only 750 Nebuloth Krakens are available globally during each event. Once all 750 have been caught, players must wait until the next event for another opportunity.
Nebuloth Kraken
How to catch the Divine Nebuloth Kraken
Follow these steps to improve your chances:
- Travel to the Alien Lagoon: Arrive before the Cosmic Eclipse begins.
- Equip your fishing rod: Use your best available fishing rod to maximize your chances.
- Wait for the event: The Cosmic Eclipse starts at XX:25 and XX:55 every hour.
- Start fishing: Cast your rod and fill the casting meter as much as possible to maximize your luck.
- Catch the Kraken: Try to catch the Divine Nebuloth Kraken before the global supply runs out.
NOTE: Arrive at the Alien Lagoon before the event starts and use your highest-luck cast. With only 750 Krakens available across all servers, you may have very few opportunities to catch one during each event.
You have around 2 tries to successfully catch Nebuloth Kraken before it’s gone
New Fishing Milestones and rewards
Steal an Egg update 12 introduces a new Fishing Milestone system that rewards players for taking their time to fish in the new Alien biome.
Fishing Milestones include:
