Be a Fish Bait All Auras Calculator
By Jim Liu · Last updated 2026-07-11
Check off the auras you already own, and the All Auras Calculator below runs a real simulation of the reroll pool to estimate how many more you need to finish the whole set - not just one aura at a time.
- 11 auras total, across six rarity tiers
- Missing Leviathan (0.2%) alone still averages ~500 rerolls
- Duplicates of auras you already own don't count toward it
- Every run below uses the same real weighted table
Which auras do you already have?

The reroll calculator on this site answers one question at a time: pick a single aura, and it solves exactly how many rerolls you need for a given confidence level. That works because single-aura odds have a clean formula - 1 minus the chance of missing every reroll in a row.
Finishing your whole collection doesn't work that way. The moment you're missing two or more auras, there's no equivalent clean equation - the classic version of this problem is called the coupon collector's problem, and even the textbook math for it assumes every item is equally likely, which auras clearly aren't. So instead of a formula, the All Auras Calculator above actually plays out thousands of simulated reroll sequences against the same real weighted table the rest of this site uses, and reports back what actually happened across all of them - the same simulate-rather-than-guess approach the Aura Roller already uses for single pulls.
Why Leviathan decides almost everything
Leviathan sits at a 0.2% roll rate, and the next-closest auras - Kraken and Solar Fin, both Legendary - are still roughly four to six times more common. That gap is big enough that in almost any realistic collection scenario, whichever gaps you have besides Leviathan will fill in well before it does. Missing only Leviathan reduces the whole problem back to the reroll calculator's single-aura case exactly, since there's nothing left to wait on - which is why the All Auras Calculator settles on ~500 rerolls for that scenario every time, no simulation variance needed to know that number.
Add a second or third missing aura from a common or uncommon tier and the total barely moves, because those tiers land in a handful of tries on average. The practical takeaway: once Leviathan is your only gap, the "collection" question and the "one aura" question are the same question. Before that, the All Auras Calculator is doing real work the closed-form math can't.
Reading your results
The All Auras Calculator reports three numbers because any one of them on its own is misleading for a rare-item problem like this. The median is the middle outcome across every simulated run - half of runs finished faster, half took longer. The average gets pulled upward by the unlucky tail (a handful of runs that go very long drag the mean up more than they'd suggest just by looking at a typical run). The 90th percentile is there for planning around bad luck specifically - it's roughly what a genuinely unlucky run looks like, not a typical one.
None of these numbers are a countdown. Every reroll is independent, so there's no signal partway through a grind that tells you "close now" - the same honest caveat the reroll calculator gives for chasing Leviathan on its own.

The math above is the theory - here's what chasing the rarest tier actually looks like in a live lobby, rerolls and all.
FAQ
How many rerolls does it take to get all auras in Be a Fish Bait?
There's no single number - it depends entirely on which auras you're still missing, which is exactly why the calculator above runs a simulation instead of quoting a fixed figure. If Leviathan is your only gap, the math simplifies to the same single-aura case the reroll calculator uses: about 500 rerolls on average. Missing more than one aura pushes that number up, usually not by much, since the easier auras tend to show up early and it's the rarest remaining one that decides how long the whole run takes.
What's the hardest aura to finish the collection with?
Leviathan, by a wide margin. At a 0.2% roll rate it is roughly four times rarer than the next-hardest auras (Kraken and Solar Fin, both Legendary), so almost any collection scenario that still needs Leviathan is bottlenecked on it specifically - the calculator flags this directly when you run it with Leviathan unchecked.
Do duplicate aura rolls help me finish my collection faster?
No. Rerolling replaces the aura you're currently wearing with a fresh weighted pick from the full table - it doesn't check what you've owned before or skip auras you already have. Landing Ripple for the fifth time does nothing for your progress toward Leviathan; every reroll is an independent shot at all 11 auras, which is also why the simulation above draws from the complete table on every single try rather than a shrinking pool.
Is there an in-game reward for owning every aura?
We haven't seen one. There's no achievement popup, badge, or bonus that fires when your collection completes - finishing the set is a self-directed goal, not something the game currently tracks or pays out for. If that changes in a future update, this page gets revisited along with the rest of the aura system.
How is this different from the reroll calculator?
The reroll calculator answers a single-aura question with exact math: pick one aura, and it solves 1 minus the chance of missing every time. The All Auras Calculator answers a different question - how long until every aura on your missing list has landed at least once - and that question doesn't have a clean formula once more than one aura is missing, so it's estimated by actually simulating thousands of reroll sequences instead.
