Roll a Fisherman Auto Sell: Enable It Safely, Tier by Tier

Quick answer

Auto Sell is a paid shop upgrade that automatically sells caught fish from the rarity tiers you enable — commons when you buy it, with rares, epics, and legendaries switched on later in the run. Mythic-and-above fish stayed out of it in observed play, and the documented safe routine is to check your next rebirth, index, and mutation needs before enabling any higher tier.

• Rarity is the only selection control: a glitched, mutated common was still sold as a common, so mutation status does not exempt a fish.
• Sales happen automatically inside the catching loop to keep a full inventory from stopping production; observed play shows no confirmation prompt or delay.
• Keep mythic-and-above fish out of Auto Sell — in observed play they stayed in inventory and duplicates were sold manually for gold.
• The Cash payout of an auto-sold fish is not documented, and neither are the exact purchase price or the trigger for each higher tier.

How Auto Sell is obtained and switched on

Auto Sell is purchased — it is not available from the start of a save. Recorded play shows it bought from the shop or upgrade area mid-run, once catches began filling storage, with commons covered from the moment of purchase. A written progression guide treats it as paid automation to schedule by budget: buy it "as soon as the cost is manageable" because it "reduces manual collection and selling."

Coverage starts at commons, and higher tiers are switched on later (see the table below). The exact purchase price, the item's precise spot in the shop, and any level or rebirth prerequisite are not documented. You can also switch Auto Sell off again — that toggle matters most around rebirths, covered in the cautions below.

Which fish Auto Sell can sell

Comparison

Comparison

Rarity tier	Auto Sell coverage in observed play	When it was switched on in the recorded run
Common	Enabled with the initial Auto Sell purchase	"we can auto sell commons, at least for now"
Rare	Enabled later in the run	"we can now auto sell rares"
Epic	Enabled after rares	"It is now time we auto sell epics. Get them out of here."
Legendary	Enabled while mythics were kept	"we can now auto sell legendaries. I have all mythics"
Mythic and above	Not auto-sold in observed play; duplicates were sold manually for gold	In-game hint: "Obtain gold by indexing fish or selling mythic plus ones"

The game's rarity ladder runs common, rare, epic, legendary, mythic, divine, and higher categories, and the written guide's rule matches the table: "use auto-sell for common or low-value rarities while keeping higher-tier fish for income, indexing, rebirth requirements, or mutation attempts."

What unlocks each higher Auto Sell tier — cost, rebirth count, or another requirement — is not documented; the recorded run only shows the tiers becoming available one by one. No species-level filter appears in documented play: rarity is the only selection control.

What Auto Sell can take that you still need

Auto Sell has no documented protection for individual fish, so it can sell catches your progression still needs. The guide's inventory warning is explicit: "Auto-selling can remove fish needed for progression. Before enabling higher-rarity auto-sell, check whether your next rebirth, index goal, or mutation plan requires those catches."

Recorded play shows the exact loss: with legendary coverage on, a rebirth-required squid was auto sold — "Oh, wait. My squid's gone. No, I SOLD THE SQUID." The player immediately turned Auto Sell off and had to catch another squid before rebirthing.

Two categories should stay out of Auto Sell:

• Mythic-and-above fish. The in-game hint points to gold here — "Obtain gold by indexing fish or selling mythic plus ones" — though the recorded player disputed the indexing half, and the written guide credits gold only to wheel results and selling high-tier fish. Treat selling mythic-plus catches as the dependable part of that hint.
• Fish your next rebirth requires. The guide's rule: "Some rebirths also require particular fish. Keep those catches."

Toggling Auto Sell off around those moments is the documented control.

The guide's pre-rebirth checklist says to "Turn off auto-sell for fish you want to preserve," and its habit list repeats: "Save fish required by rebirth objectives before enabling broad auto-sell settings." Its efficient loop is to "place your best fishers, collect automatically, sell low-value duplicates, save required fish, and let the dock generate money while you wait."

Recorded play matches the post-rebirth step — after rebirthing, the player re-enabled his top tier: "We have a whale and a megalodon. We can officially auto sell legendaries again." Whether Auto Sell settings persist through a rebirth is unknown; re-enabling afterwards is the observed practice, so check your toggles after every rebirth rather than assuming they carried over.
