Rebirth in Be a Fish Bait resets your level and currency but permanently increases your power gain through a system of rebirth points and multipliers. You enter by reaching level 100 and spending a rebirth token, which grants you a +10% power gain bonus per rebirth, stacking multiplicatively with other bonuses. This article explains the rebirth mechanics, how to maximize the boost, and common mistakes to avoid.

Formula

The power gain bonus from rebirths is calculated as:

Power Gain Bonus (%) = Rebirths Done × 10

Where:

  • Rebirths Done – the number of times you have used the rebirth feature (integer, 0 or more).
  • Power Gain Bonus – the percentage increase to all power gained from kills, quests, and fishing, applied after other multipliers.

The level required for the next rebirth follows a separate formula: Level Required = 100 × (1.5 ^ Rebirths Done). This means each rebirth raises the level threshold by 50% of the previous requirement.

Worked Example

Suppose you have completed 5 rebirths. Using the default values:

  1. Power Gain Bonus = 5 × 10 = 50%.
  2. Level required for the 6th rebirth = 100 × (1.5 ^ 5) = 100 × 7.59375 = 759 (rounded to the nearest whole level).

The calculator above shows the same: a 50% bonus and a level requirement of 759 (rounded).

How Rebirth Works in Be a Fish Bait

Rebirth is a prestige mechanic common in idle and incremental games. In Be a Fish Bait, you start as a small fish and grind experience to level up. Once you hit level 100, the rebirth option unlocks. When you activate it:

  • Your level resets to 1.
  • All currency (gold, gems) is reset to zero.
  • Your equipment and upgrades are lost (unless you have permanent upgrades that persist).
  • You gain 1 rebirth point, which permanently adds a +10% power gain multiplier.

The power gain multiplier applies to all sources of XP and currency, making each subsequent playthrough faster. This is the core loop: grind to 100, rebirth, get stronger, grind again.

Why Rebirth Is Worth It

At first glance, losing everything seems counterproductive. But the exponential nature of the power gain makes rebirth essential for progressing beyond the mid-game. Without rebirths, you would hit a wall around level 200 where enemies scale faster than your damage. With each rebirth, your effective power doubles (roughly) every 7 rebirths (since 1.1^7 ≈ 1.95). This allows you to push further and unlock new areas, fish, and abilities.

For example, a player with 10 rebirths has a +100% power gain, effectively doubling all XP and currency earned. This halves the time needed to reach the next rebirth, creating a snowball effect.

How to Choose When to Rebirth

There is no universal “best� time, but a common strategy is to rebirth as soon as you hit the required level, unless you are close to a major milestone (like unlocking a new area or a rare fish). Reasons to delay:

  • You are about to unlock a new fishing spot that gives significantly more XP.
  • You are close to completing a quest that gives a permanent upgrade.
  • You are saving currency for a high-tier equipment piece that will help you reach the next rebirth faster.

In general, early rebirths (first 5-10) should be done immediately, as the level requirement grows slowly. Later, you might want to push a bit beyond the minimum to afford key upgrades.

Common Mistakes and Misconceptions

One common mistake is hoarding rebirth points instead of spending them. Rebirth points are automatically applied as a passive multiplier; there is no skill tree to allocate them. So there is no reason to save them – they are always active.

Another misconception is that the power gain bonus is additive with other multipliers. In fact, it stacks multiplicatively with equipment bonuses, fish rarity bonuses, and event multipliers. For example, if you have a +50% from equipment and +100% from rebirths, your total multiplier is 1.5 × 2.0 = 3.0 (200% total bonus), not 150%.

Also, note that the level requirement formula (100 × 1.5^r) means the grind becomes steeper. At 20 rebirths, you need level 100 × 1.5^20 ≈ 3,325, which is a long grind even with a +200% bonus. Plan accordingly.

Comparing Rebirth to Other Progression Systems

Rebirth is similar to “prestige� in games like Clicker Heroes or Adventure Capitalist. The key difference is that Be a Fish Bait ties rebirth to a level threshold, not a currency amount. This means you must actively play (or idle efficiently) to reach the level, rather than just accumulating gold.

Compared to “ascension� systems where you keep some upgrades, Be a Fish Bait rebirth is harsher – you lose everything except the permanent multiplier. This makes it more rewarding when you do it, but also more punishing if you rebirth too early.

Costs and Requirements

The only cost to rebirth is reaching the required level. There is no in-game currency cost, no item requirement, and no cooldown. However, you must have reached level 100 at least once to unlock the feature. After that, each rebirth requires the level formula above.

There is no real-world money involved; rebirth is purely a gameplay mechanic. Some players wonder if there is a cap on rebirths – the game does not specify a hard cap, but practical limits arise from the exponential level requirement. At some point, the level required exceeds the maximum level achievable (if one exists), effectively capping rebirths.

Safety and Fair Play

Rebirth is a single-player mechanic, so there is no risk of losing progress to other players. However, be cautious with any “rebirth� button – some games have a confirmation prompt, but if you click too fast, you might accidentally reset. Always double-check before confirming.

Also, avoid using third-party tools or exploits to speed up rebirth. The game’s terms likely prohibit cheating, and it can ruin the intended progression curve. Stick to legitimate grinding.

Frequently Asked Questions

Does rebirth reset my rebirth points? No, rebirth points are permanent. Each rebirth adds to your total, and the bonus is always active.

Can I rebirth multiple times in a row? No, you must reach the required level again after each rebirth. You cannot rebirth twice without leveling up.

What is the maximum rebirth bonus? There is no stated cap, but the level requirement grows exponentially, so practical limits exist. At 50 rebirths, the bonus is +500%, but you would need to reach level 100 × 1.5^50 ≈ 6.38 × 10^10, which is likely impossible.

Does the power gain bonus affect fishing XP? Yes, it applies to all sources of power gain, including fishing, combat, and quests.

Is there any downside to rebirth? The only downside is losing your current level, equipment, and currency. If you have not unlocked permanent upgrades, you will need to re-earn them.
