Fisch Mutations Guide: Value Multipliers, Events & Enchants
Mutations multiply a fish's sale value: stackable attributes Shiny and Sparkling each apply 1.85x, the top rod-exclusive mutations reach 10x with Tryhard, and the Mutation Surge event raises all mutation odds by 15%. The Mutated enchantment adds a blanket 7% to every roll, and the Appraiser NPC can reroll mutations manually.
Quick Answer
Mutations are RNG variants that multiply fish value. Shiny and Sparkling apply 1.85x each as stackable attributes; the high band runs from Aurora at 6.5x up to Tryhard at 10x on its dedicated rod. The Mutation Surge event adds 15% to all mutation odds when the day-night cycle turns, the Mutated enchant adds a permanent 7%, and negative mutations from Unlucky at 0.5x down to Putrid at -0.5x reduce value.
The mutation system is Fisch's economy multiplier, and it is where a common fish becomes a jackpot. The database tracks well over a hundred mutation entries, but they collapse into four usable bands: stackable attributes, standard multipliers, rod-exclusive rolls, and negative traps. This guide maps every band with its numbers and the levers that raise your odds.
Technical Specifications
| Band | Examples | Multiplier | Source |
|---|---|---|---|
| Stackable attributes | Shiny, Sparkling | 1.85x each | Random roll, stacks with mutations |
| Top exclusives | Tryhard, Fabulous, Blessed | 8.5x-10x | Dedicated rods only |
| High standard | Aurora, Nuclear, Mythical, Spirit | 5.2x-6.5x | Random roll |
| Mid standard | Fungal 4x, Carrot 5x, Lunar 2.5x, Midas 2.5x | 2.5x-5x | Random or rod-boosted |
| Low standard | Silver 1.8x, Darkened 1.5x, Albino 1.2x | 1.2x-1.8x | Random roll |
| Negative | Unlucky 0.5x, Dirty 0.3x, Putrid -0.5x | Below 1x | Random roll |
The Multiplier Bands
Shiny and Sparkling are the two attributes every angler learns first: each applies a 1.85x multiplier, they stack on top of other mutations, and their odds rise during dedicated weather events. The high standard band is where session-changing money lives: Aurora applies 6.5x, Nuclear 6x, Mythical 5.5x, Abyssal 5.5x, Spirit 5.2x, and Carrot 5x. The mid band covers the early-game workhorses, most importantly Fungal at 4x from the free Fungal Rod and Carrot at 5x from the Carrot Rod.
Not every roll helps you. Unlucky and Charred halve value at 0.5x, Dirty drops it to 0.3x, Exploded nearly zeroes it at 0.1x, and Putrid applies a negative 0.5x that subtracts from the sale. Selling discipline matters: learn to read the mutation tag before confirming a sale rather than dumping inventory blind.
Rod-Exclusive Mutations
A set of mutations only rolls on their dedicated rods. Tryhard applies at a full 10x on its rod. Fabulous rolls at 9.3x with a 26% chance on its rod. Mossy at 8.7x rolls at 5% on the Elder Mossripper. Blessed at 8.5x rolls at 30% on the Seraphic Rod. Distraught at 8.5x rolls at 25% during the day and 35% at night on the Dreambreaker. Standard rods carry their own signatures: the Kings Rod improves Big and Giant mutation odds, the Midas Rod boosts Midas rolls, the Celestial and Trident rods are the only sources for Celestial and Atlantean mutations, and the Phoenix Rod raises Scorched odds.
Raising Your Odds
Three levers stack. First, enchantments: the Mutated enchant adds a blanket 7% to all mutation rolls, Abyssal adds 10% for Abyssal mutations, Noir adds 10% for Albino and Darkened, and Ghastly adds 20% for Translucent. Second, events: Mutation Surge raises all mutation chances by 15%, Night of the Luminous raises Sparkling rates by 10%, and Shiny Surge raises Shiny rates by 3%, with all of them rolling when the day-night cycle changes. Third, the Appraiser: this NPC manually rerolls mutations on a caught fish, converting spare catches into another roll at the high band.
Admin Events And The Appraiser
Beyond the standard bands, a separate tier of mutations only exists during live admin events. Entries such as Alien, Galaxy, Glacial, Radiant, Spectral, and Spicy all apply 8x multipliers but are locked to their event windows, with a handful obtainable through event-exclusive items at full chance. These cannot be farmed on demand, and any guide claiming otherwise is describing something that does not exist in the game. When an admin event does run, drop everything: an 8x roll on a decent base fish is a session-defining catch, and the event windows are short.
The Appraiser is the manual layer of the system. Taking a caught fish to the Appraiser rerolls its mutations, which converts surplus inventory into extra attempts at the high band. The discipline that pairs with it is selling hygiene: negative rolls from Unlucky down to Putrid subtract value, so check the mutation tag before confirming any sale, and route high-base fish through the Appraiser rather than dumping them blind with sell-all.
Troubleshooting & Critical Tips
- Luck compounds mutation odds: high-luck rods from the tier list are the cheapest way to see more mutation rolls per hour.
- Admin-event mutations such as Alien, Galaxy, and Glacial at 8x only appear during live admin events; treat any claim of farming them on demand as false.
- Multiplier values differ between older snapshots and current ones for a handful of entries; where sources conflict, this guide anchors to the consistent single-snapshot list and marks the rest as patch-sensitive.
- Keep one inventory slot of discipline: a Putrid roll on a high-base fish can cost you money if you auto-sell everything.
