Spending the wrong currency
Guns and tubes use Cash; normal/Lucky race rolls use 100/450 Star Shards in the community record. A weak tube is not fixed by rerolling a useful race, and a Cash farming estimate cannot promise to replenish spent shards.
A second race slot is listed at 1,000 shards and a third at 5,000. If you intend to preserve a race, reserve that cost before calculating your remaining roll budget.
Following a circular unlock route
Lost Captain’s late chain requires 15 Blobfish and opens Angler Cave. Blobfish has an Ocean location as well as the cave; sending a player only to the locked cave creates a dead end.
King Monkey’s treasure room gives Wild gear access, while the Ruined Gun is associated with Angler Cave and Lightkeeper. Similar-looking late-game item names do not make these the same quest reward.
Treating chance or conditional effects as guarantees
Crab’s 25% attack absorption is not constant 25% damage reduction. Vampire Squid’s oxygen return is catch-triggered with a 20-second cooldown, rather than healing on every shot. Shark and Sea Angel have different oxygen triggers, so their peak bonuses are not always active.
The race wiki describes pity, but its complete thresholds and distribution are not established here. The fixed-odds calculator is a labelled mathematical comparison, not the number of rolls your account is guaranteed to need.
Misreading limits and cancellations
A tube’s listed depth limit does not guarantee enough oxygen for a return trip. Carrying capacity is another separate constraint; a high damage gun does not add storage.
Holding and releasing moves the green catch bar; X cancels and loses the recorded streak. If a catch keeps failing, compare control, damage and cooldown rather than assuming a mutation or rare race is required.
