Rarity guide

How to Catch Rare Fish in Deep Fishing

Rare-fish advice is useful only when it starts with the water you can reach. This page uses official badge names and refuses to manufacture a species list.

No story spoilers

§The verified named milestones#

MilestoneOfficial wordingPractical reading
First LegendaryYou caught your first Legendary!First named rarity milestone in the checked badge list.
First MythicalYou caught your first Mythical!A later named rarity milestone.
First SecretYou caught your first Secret!The highest named rarity confirmed by the checked badge names.
First MutationYou caught your first Mutated Fish!A separate modifier milestone, not a fourth rarity label.

§A careful rarity route#

Read the label attached to the fish before deciding what to keep. The checked footage shows an EPIC rarity label, a separate GOLD modifier on another fish, and a Lionfish catch notification. These visible labels help identify what you are looking at; the frame does not establish drop odds, a complete rarity order, or a current sell-value table.

  • Keep the first named catch that completes a badge goal before turning on aggressive selling.
  • Use full casts and spend on Strength until the reachable water changes.
  • Read the live shop for luck options only after distance is stable.
  • Treat any community rarity order as a working guide, not a published drop table.
  • If the label is new, pause Auto Sell or its equivalent until the catch is identified.

§What this site does not claim#

The checked official badge endpoint provides names and descriptions, while the public game description provides the distance and rarity relationship. It does not provide a full fish catalog, per-water drop rates, mutation odds, or exact sell values. Those fields stay unknown here.

§Exotic rarity: a dated official addition#

The September 6 official announcement adds Exotic rarity, five new Exotic fish to World 1 and four to World 2. It also names a Secret / Exotic hatch minigame and pull cutscene. These are historical update counts, with current species, exact odds and a complete rarity ordering still unverified.

When checking a catch, read its rarity label separately from its mutation. The reroll announcement discusses changing a caught fish mutation; it does not document upgrading rarity through a scroll.

§FAQ#

What is the Deep Fishing rarity order?

The checked official badges confirm Legendary, Mythical, and Secret as named milestones. Community pages describe Common as the bulk baseline, but a complete official table was not available in this research pass.

Does a mutation make a fish Secret?

No official source says that. The badge list treats First Mutation and First Secret as separate achievements, so this guide treats mutation as a separate modifier.

Why am I not seeing a Secret?

Check reach and Strength before assuming a missing luck bonus. Exact Secret conditions and drop rates remain unverified.
