The official BE A FISH BAIT page confirms a new bait Aura system. Pro Game Guides describes rerolls as a way to unlock Auras, but this site does not publish exact odds, effects, pity rules, or a tier list without verified data.
What Aura confirms
The current official experience description adds a new bait Aura system to BE A FISH BAIT. That is enough to say Aura is a live system worth checking when you join. It is not enough to state a complete list of Aura names, effects, rarity weights, or a best Aura for every player.
The same update copy mentions daily rewards and a 1.5x VIP Training Area. Those are nearby systems, but they should not be collapsed into one unsupported Aura formula. The codes page is relevant because current codes may grant rerolls or spins according to secondary coverage, while the gameplay page explains the broader loop that Aura sits inside.
Rerolls and secondary evidence
Pro Game Guides describes rerolls as being used to unlock Auras and recommends opening the Aura menu after collecting them. That is useful secondary coverage for the player task: a player who receives a reroll needs to know which menu or system to look for. It does not verify the hidden probability model, pity behavior, or whether an Aura modifies catch speed, sell value, mutation chance, or training in the current build.
When a player asks for a BE A FISH BAIT Aura tier list, the honest answer is that a ranking needs criteria. A useful tier list would need tested Aura effects, a declared objective such as catch speed or economy, and a checked date tied to the current Delulu Update. Without that, “best” is just a recycled claim.
What to do with a reroll
Use a current code if it grants a reroll, open the in-game Aura area, and record what the game actually displays. Keep the result separate from a public database until the name, effect, and rarity can be checked more than once. If you are tracking your first run, mark the Aura task in the local checklist without treating a particular roll as required.
Held topics
This page does not publish an odds calculator, a tier list, or a guaranteed route to a specific Aura. Those pages are listed as draft opportunities in the build artifacts. They can be promoted after the game or an authoritative source exposes stable weights and effects. Until then, the source policy is the reliable answer for why the page stays conservative.
