Be The Final Boss Waves, Boss Checkpoints, and Skill Tree
Plan Be The Final Boss wave runs with confirmed boss checkpoints, formation diagnosis, Population and Unit Damage upgrades, weapons, Coins, and Souls.
How the endless-wave run works
Be The Final Boss sends heroes toward the player's castle in an endless defense run. You place minions, enter the combat zone, attack with the boss character, and continue until the formation and player are defeated. Between attempts, Coins, Souls, unit levels, weapons, and skill-tree upgrades improve the next run.
The word “endless” does not mean every wave feels the same. Public gameplay identifies boss checkpoints, increasing pressure, and unlocks tied to deeper progression. One first-session recording reaches a boss around Wave 25. A longer recording discusses the Wave 50 boss, while another interface note says two-times speed unlocks at Wave 100.
| Checkpoint | What is visible in public gameplay | Why it matters |
|---|---|---|
| Early waves | Basic heroes test the starting three-unit formation | Reveals whether placement and roles make sense |
| Wave 25 | A boss checkpoint is identified | First useful target for a beginner build |
| Wave 50 | A later boss is discussed in a longer run | Tests sustained durability and damage |
| Wave 100 | Two-times speed is shown as an unlock condition | Long-term convenience target, not an early build requirement |
The official Roblox listing confirms the endless hero-wave premise. The checkpoint and upgrade observations come from AccelToWin's gameplay video and cashplaysblox's extended session.
Read the first point of failure
The wave number on the defeat screen is less useful than the first thing that went wrong. A front line that collapses early needs a different response from a healthy formation that cannot damage the boss quickly enough. Watch the sequence, then purchase the smallest upgrade that changes it.
| First failure | What it means | Upgrade to inspect |
|---|---|---|
| Melee units disappear immediately | Front-line durability is too low | Unit level, stronger melee summon, or defensive effect |
| Heroes collect behind the first target | Damage is too low or too single-target | Unit Damage, ranged damage, or area unit |
| Strong units stay in inventory | Placement capacity is the limit | Population |
| All minions survive but the boss character contributes little | Personal damage lags behind | Weapon or Boss Attack tooltip |
| Formation clears but progress earns resources slowly | Economy is the limit | Coin Income tooltip and efficient run length |
| Boss arrives with a damaged formation | Earlier waves consume too much health | Better role balance before boss-specific spending |
Do not leave the combat zone to avoid damage. Recorded gameplay shows a warning that tells the player to return. If the timer expires or the run stops, the attempt loses value. Use minion positioning and player movement inside the allowed area instead.
After a defeat, repeat a similar formation with one major upgrade. If Wave 18 becomes Wave 27 after adding Population, the extra active unit likely solved a real constraint. If the result barely changes, the lineup may need durability or damage rather than another slot.
Skill-tree priorities for deeper waves
The early skill tree visibly includes Population and Unit Damage. The longer footage also shows labels such as Castle Buff, Coin Income, and Boss Attack. Exact values can change and were not consistently readable, so the correct priority depends on the current tooltip and the run's failure pattern.
Population is powerful when the player owns a useful unit that cannot be placed. Unit Damage is better when every slot is filled and minions survive long enough to attack. Boss Attack matters more when the player is safely contributing throughout the run. Coin Income is a progression choice: it sacrifices some immediate combat power for faster purchases later, so it is easier to justify after the formation can clear reliably.
| Skill direction | Buy it when | Delay it when |
|---|---|---|
| Population | A good fourth unit is waiting outside the lineup | Current three units already die instantly |
| Unit Damage | The line survives but clears too slowly | No durable unit keeps heroes occupied |
| Boss Attack | The player attacks safely for most of the run | The boss spends the run fleeing after early collapse |
| Coin Income | Runs are stable and the next upgrade is expensive | A small combat upgrade would reach the next checkpoint now |
| Castle Buff | The current tooltip addresses the observed failure | Its effect is unclear or another bottleneck is more obvious |
Avoid distributing one point into every branch merely to unlock labels. A focused purchase is easier to test. Reach the same checkpoint, compare survival and clear speed, then decide whether to continue that branch.
Weapons, Coins, and Souls between attempts
Gameplay shows a weapon shop and a progression step to a Gilded Longsword. It also shows Coins and Souls used across the broader upgrade and summon loop. These resources should not be treated as interchangeable. Coins can support immediate purchases and the active betheboss code is currently reported to give 500 Coins. Souls appear in summons and higher-cost progression, including a free-spin result of 50 Souls in one session.
Use a post-run budget instead of spending in menu order:
- Repair the formation's first failure with a unit level, role replacement, or Population.
- Improve Unit Damage when surviving minions cannot finish waves.
- Upgrade the weapon when the player attacks consistently and the price does not block a more important unit change.
- Save Souls when random rolls are unlikely to improve the active lineup.
- Consider income upgrades after the run is stable enough to produce repeated returns.
| Resource choice | Immediate result | Long-term tradeoff |
|---|---|---|
| Unit level | Stronger active minion | Benefits only the unit you continue using |
| Population | Another active placement slot | Needs a useful extra unit to fill it |
| Weapon | Higher personal contribution | Does not stop a weak front line from collapsing |
| Summon roll | Chance at a new role or rarity | Can consume Souls without improving the lineup |
| Coin Income | Faster future purchasing | May delay the combat power needed for the next boss |
Paid convenience features can appear around speed, auto-roll, or AFK behavior. One recording calls out paid fast-forward or automation options, while the release text mentions auto battle. Confirm the current price and unlock status in the live client. A wave strategy should still function without assuming a paid feature.
Prepare specifically for boss checkpoints
For Wave 25, the priority is arriving with a functioning formation. If ranged units have already died, the boss is not the real problem. Strengthen the front layer or clear earlier heroes faster. If all units arrive healthy but the boss survives too long, concentrate damage through the best sustained minion, Unit Damage, or a weapon upgrade.
Wave 50 demands consistency for twice as long. Area damage becomes more valuable when regular waves group up, while unit levels and durable melee bodies protect the damage line across repeated encounters. Saving everything for one expensive summon can delay several upgrades that would carry the formation through the waves before the boss.
Wave 100 is a long-term target because the interface associates it with two-times speed. Do not build exclusively for the convenience unlock on a new account. First make Wave 25 repeatable, then improve the Wave 50 route. Stable checkpoints make resource gains and later experiments easier.
Use this short review after every serious attempt:
- Highest wave reached and whether it was a boss wave.
- First unit to fall and which heroes reached it.
- Number of active placement slots.
- Skill purchased before the run.
- Weapon equipped.
- Coins and Souls reserved after the run.
This is player-facing diagnosis: every answer should lead directly to the next purchase or formation change.
Be The Final Boss waves FAQ
Is Be The Final Boss really endless?
The official description says players defeat endless waves of heroes. Runs still contain boss checkpoints and end when the player's defense fails, so “endless” describes the mode rather than an expectation that a new account never loses.
What wave has the first boss?
Public gameplay identifies Wave 25 as an early boss checkpoint. Another recording discusses Wave 50. Updates may change pacing, so confirm the marker in the current client.
Should I upgrade Population or Unit Damage first?
Choose Population when a useful unit is blocked by the placement limit. Choose Unit Damage when all active slots are filled, the formation survives, and heroes are not dying quickly enough.
How do I unlock two-times speed?
One recorded interface associates two-times speed with reaching Wave 100. Check the current live requirement because unlock conditions and paid alternatives can change after patches.
