Fish an Anime RNG Potions: Types, Effects, Durations, and Best Use

Potions in Fish an Anime RNG are temporary consumable boosts. The Boosts Shop sells five — Cash, Gems, Mutation, Fast Catch, and Luck — while Golden, Double Power, and the event-triggering potions come from codes, Cosmic Boxes, gameplay rewards, and two NPC vendors. Only the summoned event potions have published durations (3–10 minutes); for everything else, the timing rule is the same: activate right before a focused fishing session, never before logging off.

Data table

Event (Potion Triggered)	Duration	Boost And Effects
Cyberspace	3 minutes	Gives a 10x Luck boost
Dreamspace	3 minutes	Gives a 4x Luck boost; every catch has either the Party, Void, or Lunar mutation
Heaven's Collide	5 minutes	Gives a 2x Luck boost; all character types are 2x more likely to get mutated; Gems and Stars fall from the sky, and the Stars can turn held characters into Angelic or Gold
Hell's Gates	10 minutes	Gives a 4x Luck boost; high chance of Demonic, Dracula, Nightmare, and Blood mutations; Gems and Stars fall from the sky, and Stars can give held characters Blood mutations
Lucrative Realization	5 minutes	Gives a 5x Catch Speed boost; you can get another 5x Catch Speed after becoming Realized
Party	5 minutes	Gives a 2x Catch Speed boost; your held characters can get the Party mutation
SUB ZERO	5 minutes	Gives a 2x Luck boost; high chance of Frozen, Electric, and Diamond mutations; held characters can get Frozen
Sakura Season	5 minutes	Gives a 2x Luck boost, 2x Cash boost, and 1.25x Food boost

None of these eight events occur naturally — they're triggered by players who use specific potions bought from special NPCs or the Boosts Shop in the central hub. During Hell's Gates, Heaven's Collide, SUB ZERO, and Party, equip a character from your hotbar so it has a chance of being mutated. And if you've run across mentions of a "skyfall potion": no potion by that name exists — the Gems and Stars falling from the sky belong to the Heaven's Collide and Hell's Gates events.

Where event potions come from: the upgrade tree, Selene, and Angelia

Checklist

• Potion upgrade tree

  Invest Gems and Cash in the Potion upgrade tree to unlock special potions in the Boosts Shop, including ones that trigger events.

• Selene (traveling merchant)

  A 2% chance to appear on a server every 20 seconds; she stays 3 to 4 minutes and sells Heaven's Collide Potion, Meteorite Potion, Honey Potion, and Sinister Potion. The Heaven's Collide Potion is reported at 25,000 gems (some videos spell her name 'Celine').

• Angelia

  Appears at random times with the rarest potions in the game — a lower spawn rate than Selene and limited stock. She sells Forgotten Potion, Cybernetic Glitch Potion, Dreamer Potion, and Party Potion.

Buying from the Boosts Shop: restock, stock-outs, and price scaling

The Boosts Shop sells the standard potions from a rotating stock that restocks roughly every 20 minutes, and the shelves can sit empty between restocks. Prices scale steeply as you move up: guides describe potion prices starting around 7.5k, then reaching 2 billion, then 20 trillion, with gem-boosting potions priced even higher. Because potions are limited-use consumables, don't purchase on every restock — buy once your income has outgrown those prices, or only occasionally with a specific session in mind. The boost is temporary, so overspending just burns cash.

Free and player-sourced potions: codes, packs, Cosmic Boxes, gifts, and trading

Redeeming codes in the Store is the main free route. September 2026 code lists credit current milestone codes with Potion Pack I and Potion Pack II bundles plus Gems, while August 2026 wiki listings credited older milestone codes with Golden Potions and Double Power Potions that later lists mark expired. Codes and Cosmic Boxes frequently award Luck Potions, Golden Potions, and Double Power Potions, and Cosmic Boxes can open into potions alongside cash, gems, and units. Limited-time packs have bundled numerous potions in bulk, and Robux-shop gifts can also contain potions. Finally, potions are tradable between players at the Trade Hub — fishing rods, cash, and Cosmic Boxes are not. What Potion Pack I and Potion Pack II actually contain isn't documented, and code availability changes quickly with lists disagreeing on status and rewards, so check the codes guide and verify current rewards in-game before counting on any specific code.

How potion durations work and how to extend them

The five Boosts Shop potions all run on timers, but their exact base durations aren't published — the 3–10 minute windows in the event table above are the only documented potion durations. What is documented is how the timers behave and how to stretch them:

Tips

Timers start when you activate

Potions run on a timer that starts when activated — activate them right before a fishing session rather than after, or the window is wasted.

Potion Time upgrade (cash)

Multiplies your Total Potion Time at +1% per level, up to a maximum level of 20, with an initial cash price of 2.5T$.

Gem Store option

Gameplay footage reports a 'Potions last longer' purchase in the Gem Store.

2x Potion Time gamepass

Doubles potion duration. Listings currently show conflicting prices — 40 and 49 Robux — so check the in-game store before buying.

Stacking and combining potions

Treat different potion effects as compatible: the standard guidance is to use compatible boosts together during long active sessions for compounded progression, and gameplay footage shows players popping all of their potions at once before a farming stretch. What's not documented is the same-type rule — whether activating a second potion of the same kind stacks its multiplier, refreshes the timer, or is blocked while one is active. Combining different potion types is supported practice; same-type stacking behavior is unconfirmed, so don't double up on one type expecting a specific result until you've seen how it behaves in-game.

Luck Potion timing, step by step

Redeem steps

• Build income and fishing power first

  Luck potions raise odds rather than guaranteeing rares, so they pay off when you can generate many fishing attempts. Early players shouldn't sink everything into luck yet.

• Prepare before activating

  Organize your base, collect your cash and resources, check your fishing power, and make sure your inventory has space for new characters.

• Activate the potion immediately before you start fishing

  Not before logging off, and not during a session you expect to cut short.

• Fish continuously for the entire duration

  Time spent in menus or away from the pond wastes the window.

• Stock up from codes and save them

  Some codes provide luck potions and gems — save those potions for these dedicated active sessions.

Best potion by farming goal

More mutations on catches: a Mutation Potion — burn it during natural event windows that already raise mutation odds (such as Blizzard) rather than a Cash Potion; Mutation Potions also raise your general mutation chance.

Mutations on held characters: the event potions — Hell's Gates, Heaven's Collide, SUB ZERO, and Party. Equip a character from your hotbar during the event so it can be mutated, and save your best characters to hold out during mutation events.

Angelic or Gold on your best characters at scale: Heaven's Collide Potion — start the event near the water and keep fishing so falling Stars hit as many held characters as possible.

A golden mutated unit: Golden Potion — use it during rare hunts or right after buying a major rod upgrade.

A progression push or power leveling: Double Power Potion — save it for periods when increasing power directly helps push progression, and pair it with leveling your strongest placed characters using food.

Gem income: Gems Potion, which multiplies Gem payouts such as Lemon Stand income.

Any potion at all: save them for focused, uninterrupted fishing sessions. Activate immediately before a focused session so less of the effect is wasted, and redeem code potions when you plan to play a while — not when logging off. Exact multipliers for the shop potions aren't published; only the summoned-event boosts carry numbers, and Luck Potion timing follows the step-by-step rules above.
