Be a Fish Bait: All Aura Rarities & Roll Chances

In the Roblox game Be a Fish Bait, auras come in different rarities, and each rarity has a specific roll chance when you spin for an aura. This article explains every aura rarity, its exact roll chance, and how the rolling system works.

Formula

The rarity tier is determined by the roll chance percentage you input. The formula maps the chance to a tier:

• Tier 1 (Common): chance > 10%
• Tier 2 (Uncommon): chance > 1% and ≤ 10%
• Tier 3 (Rare): chance > 0.1% and ≤ 1%
• Tier 4 (Epic): chance > 0.01% and ≤ 0.1%
• Tier 5 (Legendary): chance ≤ 0.01%

Each variable is defined as:

• r – the roll chance percentage (0 to 100).

Worked Example

If you enter a roll chance of 1% (the default), the formula checks: 1% is greater than 0.1% and less than or equal to 1%, so the rarity tier is 3 (Rare). The calculator shows “3� as the result.

All Aura Rarities and Roll Chances

In Be a Fish Bait, there are five aura rarities, each with a distinct roll chance. The rarer the aura, the lower the chance of rolling it. Here is the complete list:

• Common – 50% roll chance
• Uncommon – 30% roll chance
• Rare – 15% roll chance
• Epic – 4.5% roll chance
• Legendary – 0.5% roll chance

These chances are the base probabilities; some in-game events or items may temporarily modify them, but the values above are the standard ones.

How the Rolling System Works

When you roll for an aura, the game uses a random number generator (RNG) to pick a number between 1 and 100. The number determines which aura you get based on the cumulative probabilities. For example:

• If the number is 1–50, you get a Common aura.
• If the number is 51–80, you get an Uncommon aura.
• If the number is 81–95, you get a Rare aura.
• If the number is 96–99.5, you get an Epic aura.
• If the number is 99.6–100, you get a Legendary aura.

Each roll is independent, meaning past rolls do not affect future ones. This is a common misconception – some players think that after many rolls, a legendary is “due,� but that is not how probability works.

How to Choose an Aura

Choosing an aura depends on what you value in the game. If you want to show off rare cosmetics, go for Legendary or Epic auras. If you prefer consistent effects or boosts, a Common or Uncommon aura might be more practical. Some auras have special visual effects or stat boosts, so check the in-game description before deciding. Remember, rarity does not always mean better gameplay – it often just means more exclusive.

Common Problems and Misconceptions

One common problem is players spending all their currency on rolls without understanding the odds. Another misconception is that using a “lucky� item guarantees a rare aura – it only increases the chance slightly, not to 100%. Also, some players think that rolling at a specific time or location improves chances, but there is no evidence for that; the RNG is uniform.

Comparison with Other Games

Many Roblox games use similar rarity systems. For example, Pet Simulator has tiers like Common, Uncommon, Rare, Epic, and Legendary, but the exact chances differ. In Be a Fish Bait, the Legendary chance of 0.5% is relatively high compared to some games where legendary items are 0.1% or lower. This makes the game more forgiving for players who want rare auras.

Costs and How to Get Rolls

Rolls are typically obtained using in-game currency, which you earn by catching fish or completing quests. You can also buy rolls with Robux, but the exact prices vary and are not officially published. To maximize your rolls, focus on completing daily quests and selling rare fish. There is no real-money cost to play, but optional purchases exist.

Safety and Fair Play

Always play within the game’s rules. Using third-party scripts or hacks to increase roll chances is against Roblox’s terms and can result in a ban. Also, be cautious of websites that claim to offer free rolls – they are often scams. Stick to official game features.

Frequently Asked Questions

What is the rarest aura in Be a Fish Bait?

The rarest aura is the Legendary aura, with a roll chance of 0.5%. It is the most sought-after due to its unique appearance and prestige.

Can I increase my chances of getting a rare aura?

Yes, some in-game items or temporary boosts can increase your roll chance, but they are limited. For example, a “Lucky Charm� might double your chance for a single roll, but it still does not guarantee a rare aura.

Do roll chances reset daily?

No, roll chances are fixed and do not reset. Each roll is independent, so the probability remains the same every time.

How many rolls do I need to get a Legendary aura?

On average, you need about 200 rolls to get one Legendary aura, because the chance is 0.5%, so 1 / 0.005 = 200. However, this is an average – some players get it sooner, others later.

Is there a pity system?

As of now, there is no official pity system in the game. Your chances do not increase after multiple failed rolls.

Can I trade auras with other players?

Currently, auras are not tradeable. They are bound to your account once obtained.
