What Is Sol's RNG?
Sol's RNG is a Roblox game developed by Sol's Studio where the core gameplay loop revolves around rolling for auras. Each aura has a different rarity, and the rarer the aura, the harder it is to obtain. The game has been running since early 2024 and has grown massively through a series of updates called Eras and Eons. The latest major update, Eon 1-20, continues to expand the game with new auras, items, and mechanics.

The fishing update, which arrived in Eon 1-7, added a completely new progression path. Instead of relying purely on RNG rolls, you can now head to the ocean, catch fish, and sell them for Fish Points. Those points translate into potions and gear that boost your luck, making fishing a practical way to speed up your aura collection.

How Fishing Works
To start fishing, walk to any coastal edge of the map where water is visible. When you get close enough, a UI pops up showing the fishing spot and a Fish button. Click it and the fishing process begins.

Fishing has two phases:

1. Waiting: You wait for a fish to bite. Random messages appear in the dialogue box during this phase. It usually takes a few seconds.
2. Reeling: Once a fish bites, the reeling minigame starts. A blue bar with an arrow appears, along with a green zone and a white progress bar. Keep the tip of the blue bar inside the green zone to fill the white bar. There is a red line near the end of the white bar. If your progress is above that red line when the minigame ends, you catch the fish.

You do not need a fishing rod or bait. The mechanic is available to every player for free. The difficulty of the reeling minigame varies by location. Some spots are tagged Normal or Hard, and fishing in those areas gives you access to rarer, heavier fish.

All Fish Rarities and Mutations
Fish in Sol's RNG come in four main rarities, each with a point multiplier that determines their sell value:
[b]Rarity[/b] | [b]Point Multiplier[/b] Common | 1x Uncommon | 1.5x Rare | 2x Legendary | 2.5x On top of rarity, fish can have mutations tied to the biome you are fishing in. These mutations multiply the sell price significantly:
[b]Biome[/b] | [b]Mutation[/b] | [b]Multiplier[/b] Windy | Ruffled | 1.5x Snowy | Crusted | 1.5x Rainy | Slick | 1.5x Sandstorm | Rough | 2x Hell | Charred | 2.5x Starfall | Shimmering | 3x Corruption | Tainted | 3.5x Null | Hollow | 4x Dreamspace | Lucid | 4.5x Glitched | Fragmented | 5x The sell price formula is straightforward: Weight x Rarity x Mutation = Sell Price. For example, a 15kg Spinepuff (Rare, 2x) with the Ruffled mutation (1.5x) would sell for 45 Fish Points.

Biome-Exclusive Fish
Some fish only appear in specific biomes. If you are not in the right biome, you will not catch them. Here are the biome-exclusive fish:

• Windy: Flying Fish, Wahoo, Sailfish, Striped Marlin
• Snowy: Coelacanth, Bluefin Tuna, Antarctic Icefish
• Rainy: Monk Fish, Pelican Eel, Goblin Shark, Umbrella Octopus
• Sandstorm: Skull Piranha, Skull Seahorse, Skull Mackerel, Skull Moray Eel
• Hell: Obsidian Tiger Oscar, Magma Discus, Ripsaw Catfish
• Starfall: Ghost Shark, Tripod Fish, Ocean Sunfish Fry, Barreleye, Starfish

These fish can still gain the mutation of their native biome, so a Starfall-exclusive fish with the Shimmering mutation is a valuable catch.

The Fish Shop and What to Buy
Once you have caught some fish, head to Captain Flarg's shop on the southern side of the map. Take a right from Jake's Shop and walk straight to find it. Sell your fish for Fish Points, then spend them on potions and items.

Here is what the Fish Shop currently offers:
[b]Item[/b] | [b]Price (Gems)[/b] Lucky Potion | 15 Speed Potion | 15 Gear Basing | 70 Wind Essence | 70 Icicle | 70 Rainy Bottle | 70 Haste Potion III | 100 Fortune Potion III | 100 Gladiator Potion | 300 Eternal Flame | 900 Curruptaine | 1,200 Hour Glass | 1,500 NULL? | 1,500 Potion of Bound | 2,000 Warp Potion | 4,500 Heavenly Potion | 5,500 The Lucky Potion and Speed Potion are the cheapest entry points. If you are saving for something big, the Heavenly Potion at 5,500 gems is one of the most expensive items in the shop.

Tips for Earning Fish Points Fast
Fishing in Hard difficulty spots gives you access to rarer fish with higher base values. Always check the difficulty tag before you start fishing.

Aim for biome-exclusive fish. A Starfall fish with a Shimmering mutation sells for significantly more than a common fish with no mutation.

Save your Fish Points for high-impact potions. The Gladiator Potion and Eternal Flame are popular choices because they provide lasting benefits that speed up your overall progression.

The game updates every two weeks, so new fish and biomes get added regularly. Keep an eye on the update log to stay ahead of new content.

FAQ
How do I unlock fishing in Sol's RNG?
Fishing is available to all players by default. Just walk to any ocean edge and click the Fish button when the UI appears. No quests or items are required.

What is the rarest fish in Sol's RNG?
The Gwrosse is widely considered the rarest fish in the game. It is an Uncommon rarity fish, but its low spawn rate makes it hard to catch.

Can I fish in any biome?
Yes, but the biome determines which fish you can catch and which mutations are available. Biome-exclusive fish will only appear when you are fishing in their specific biome.

How often does Sol's RNG get updated?
The developers release updates every two weeks. Each update is called an Eon and typically adds new auras, fish, items, or mechanics.

What do I do with Fish Points?
Spend them at Captain Flarg's Fish Shop on potions, gear, and exclusive items. The shop is on the southern side of the map, past Jake's Shop.

Is fishing better than rolling for auras?
They serve different purposes. Fishing gives you a steady income of Fish Points that you can convert into luck-boosting potions. Rolling is still the primary way to get auras directly. Most players use both.
