Be The Final Boss Endless Mode Tips: Reach Wave 70+

Endless Mode in Be The Final Boss starts at Wave 51 and continues until your castle finally falls, with the late-game scaling curve punishing every uninvested system and rewarding the BOSSes who balance their skill tree across all four branches. Most players who clear Wave 50 cap out around Wave 58-62 because they relied on a single defensive layer (usually Castle Defense) and neglected Population, Economy, or Boss Power scaling. This guide covers the specific late-game mechanics, the armor system stacking from UPD2, the soul economy at high waves, and the minion cycling rhythm that lets veteran BOSSes push past Wave 70 consistently. Treat this as the post-checkpoint continuation of the Wave 25 Boss Strategy guide, since every system you build for Wave 25 is the foundation you scale for Endless.

What Actually Changes at Wave 51

The transition from Wave 50 to Wave 51 in Be The Final Boss flips three scaling axes simultaneously. Hero count growth jumps from 8% per wave to 25% per wave for the first five waves, then settles at 15% per wave from Wave 56 onward. Hero tier rotation shifts from "elite plus regular" to "elite plus hero amplifier" with one of the new Endless archetypes (amplifier, soul drainer, castle rusher) appearing every other wave. Castle chip damage from incidental hero attacks scales by +12% per wave instead of the previous +5% per wave, which means a BOSS who ignored Castle Defense will see their HP drop from full to 50% in roughly 8 waves instead of 20.

The transition is designed to expose single-system builds. A BOSS who relied on Castle Defense alone will watch their minions get overwhelmed by the doubled hero count. A BOSS who relied on Population alone will see their castle chipped to death by the AOE elite heroes. A BOSS who relied on Economy alone will have the coins to spend but no army to defend with. The late-game scaling curve demands balanced investment across all four branches, plus the armor system from UPD2, plus a Doomfist that is consistently resummoned within 5 seconds of dying.

The Three Endless-Specific Hero Archetypes

Endless Mode introduces three hero archetypes that do not appear in the standard wave progression, and ignoring them is the fastest way to collapse before Wave 60:

• Hero amplifiers — boost nearby hero stats by 15% per stack, stacking up to 4 times. The counter is spreading minion placement across 4+ tiles so the amplifier cannot chain stacks. Without proper spread, an amplifier can boost a single hero to deal 60% more damage, which collapses your front line within one wave.

• Soul drainers — reduce your soul generation rate by 20% on death and persist as a debuff for 30 seconds. The counter is Doomfist AOE damage — Doomfist's burst can one-shot soul drainers before they apply the debuff. A BOSS without Doomfist will see soul generation drop to near-zero by Wave 55, which starves the minion resummoning economy.

• Castle rushers — sprint directly toward your castle, ignoring minions and chokepoints entirely. The counter is Castle Defense 4 plus a dedicated chokepoint tank at the back of the formation. A BOSS without a back-line tank will lose the castle in 2-3 waves of castle rusher spawns.

The Armor System Stacking From UPD2

The armor system introduced in UPD2 is the single largest Endless Mode progression lever, and stacking multiple armor pieces is what separates Wave 60 BOSSes from Wave 75 BOSSes. Each armor piece adds a multiplicative HP bonus to your castle and a multiplicative damage bonus to your weapon, with the bonuses compounding across the full armor set. The base armor pieces are unlocked through the UPD2 battlepass, while the legendary armor pieces require either a paid Robux purchase or a substantial coin grind through Endless Mode itself.

The stacking math is straightforward: a BOSS with three armor pieces sees roughly +45% castle HP and +30% weapon damage on top of the base stats. A BOSS with the full six-piece set sees roughly +110% castle HP and +85% weapon damage, which transforms the late-game scaling curve from "I will fall at Wave 65" to "I will fall at Wave 80+". The armor is the difference between an average Endless run and a top-100 leaderboard run, and it should be your highest-priority grind target after you clear Wave 50 for the first time.

Armor Acquisition Order

The optimal armor acquisition order in Endless Mode prioritizes castle HP pieces first, then weapon damage pieces, then utility pieces. The reasoning is that Endless Mode punishes insufficient castle HP far more harshly than insufficient weapon damage — a BOSS with full weapon damage but base castle HP will fall at Wave 58, while a BOSS with full castle HP and base weapon damage will fall at Wave 65. The priority order is:

1. Chest plate — adds the largest single HP bonus (roughly +25%)

2. Helmet — adds the second largest HP bonus (roughly +20%) plus minor damage reduction

3. Boots — adds movement speed and minor HP (roughly +12%)

4. Gloves — adds the largest single damage bonus (roughly +20%)

5. Belt — adds utility bonuses (soul generation rate, wave reward bonus)

6. Shoulders — adds the capstone legendary bonus (roughly +30% HP plus +25% damage)

Soul Economy at High Waves

Soul generation in Endless Mode plateaus around Wave 60 if you have not invested in the Soul Discount branch of the Elite Minion Slot. The plateau happens because the soul drainer hero archetype reduces your generation rate by 20% per spawn, and the spawn rate of soul drainers accelerates past Wave 55. A BOSS without Soul Discount will see their soul counter drop from roughly 120 per wave at Wave 50 to 60 per wave at Wave 60, which is below the threshold needed to sustain Doomfist resummoning plus standard minion cycling.

The fix is the Soul Discount node from the Elite Minion Slot branch, which reduces minion resummoning cost by 15% and increases soul generation by +10%. The node is roughly 300 coins of investment, but the return is dramatic — Doomfist resummoning drops from 120 souls to 102 souls, and the per-wave soul generation stabilizes around 100-110 instead of collapsing to 60. The Soul Discount node is the highest-ROI Endless Mode investment you can make after the armor system stacking.

Minion Cycling Rhythm

Minion cycling in Endless Mode is the discipline of replacing dead minions within 5 seconds of their death, before the castle chip damage compounds. The rhythm is straightforward to learn but difficult to sustain across a 90-minute Endless session. The recommended cycle is: place the minion, monitor its HP, resummon the moment it dies, upgrade if souls are healthy. A BOSS who cycles every 8-10 seconds instead of every 5 will see their army shrink to 4-5 active minions by Wave 65, which is below the Population cap and exposes the castle to direct AOE damage.

The rhythm compounds with the Soul Discount node. With Soul Discount, every cycle costs roughly 85-110 souls depending on the minion type, which is sustainable above the 100 souls per wave threshold. Without Soul Discount, every cycle costs 120-150 souls, which becomes unsustainable past Wave 60. The math dictates that Soul Discount is mandatory for any serious Endless push.

Skill Tree Endgame Configuration

The endgame skill tree configuration for Endless Mode is roughly 5,000 coins of investment across all four branches plus the Elite Minion Slot. The configuration is balanced rather than specialized, because Endless scaling punishes single-system builds. The recommended endgame layout is:

• Population 1-4 (eight minion cap) — 950 coins

• Castle Defense 1-4 (full HP scaling plus regen) — 1,400 coins

• Economy 1-4 (Treasure Wave passive online) — 1,250 coins

• Boss Power 1-3 (weapon damage multiplier) — 540 coins

• Elite Minion Slot (Doomfist unlocked) — 400 coins

• Soul Discount (sustain soul economy) — 300 coins

The total is 4,840 coins, which takes roughly 6-8 weeks of regular play to accumulate. The configuration is not the absolute maximum — you can push to Boss Power 4, Weapon Mastery 2, and the Castle Fortification branch — but it is the minimum for a reliable Wave 65 push.

Why Population 4 Is Non-Negotiable

Population 4 (the eight-minion cap) is the single most important Endless Mode threshold, because every system in the game scales with minion count. Castle Defense is irrelevant if you have no minions to tank the AOE pulses. Economy is irrelevant if you have no minions to kill for soul generation. Boss Power is irrelevant if you have no minions to hold the line while your weapon swings. The eight-minion cap is the foundation that every other system stands on, and a BOSS who has not yet maxed Population should not attempt serious Endless Mode runs.

The cap also interacts with the Elite Minion Slot — Doomfist counts against the Population cap, which means a BOSS with Population 4 can field Doomfist plus seven regular minions. A BOSS without Population 4 can field Doomfist plus three regular minions, which is not enough to hold the line in Endless. The fix is to grind Population 4 before any serious attempt at Endless, regardless of how tempting the Elite Minion Slot looks.

Why Castle Defense 4 Matters More Than Castle Defense 3

Castle Defense 4 adds the Castle Regen passive, which heals 2% HP per wave clear. The regen is decisive in Endless Mode because the late-game scaling curve chips your castle at roughly 8-12% per wave without counterplay, and the regen offsets roughly half of that chip. A BOSS with Castle Defense 3 but no regen will fall at Wave 65 because the cumulative chip outpaces the heal-from-wave-clear by roughly 4% per wave. A BOSS with Castle Defense 4 will hold at roughly 70-80% castle HP through Wave 70, which is enough buffer to survive the random spikes.

The regen also compounds with the armor system from UPD2, which adds multiplicative HP. The combination of additive Castle Defense nodes, multiplicative armor bonuses, and per-wave regen is the only reason Wave 75+ clears are possible at all.

Late-Game Minion Cycling Strategies

Endless Mode minion cycling has three distinct patterns based on the wave band you are playing. The pattern choice matters because the armor system stacking changes the math on which minions survive longest.

Wave 51-60 Cycling Pattern

During Wave 51-60, the standard cycling pattern is two tanks in front, four damage dealers behind, Doomfist at the chokepoint, and one flexible slot. Replace dead minions within 5 seconds and use Doomfist as the burst damage dealer against hero amplifiers and soul drainers. The flexible slot is usually a high-tier ranged minion that you swap to Doomfist when Doomfist dies. The pattern is sustainable with Soul Discount online and produces roughly 3-5 minion deaths per wave.

Wave 61-70 Cycling Pattern

During Wave 61-70, the cycling pattern shifts toward heavier tanks and faster Doomfist cycles. Replace the flexible slot with a second tank, and reduce the ranged damage dealer count from four to three. The reasoning is that the late-game scaling curve punishes squishy damage dealers with one-shot kills from elite AOE heroes, while tanks with the armor system stacking can survive two or three AOE pulses. Doomfist cycles become more frequent — roughly every 8-12 seconds instead of every 15-20 — which requires Soul Discount plus a higher Population cap to sustain.

Wave 71+ Cycling Pattern

Past Wave 71, the cycling pattern is dominated by Doomfist. Drop the second tank and run Doomfist plus seven high-tier damage dealers. The reasoning is that the late-game scaling curve makes tanks unsustainable (they die faster than you can resummon them), while Doomfist's AOE burst damage deletes hero clusters before they can apply their damage multipliers. A BOSS in Wave 71+ is essentially playing Doomfist as the primary defender, with the rest of the army acting as cleanup. The pattern is the highest-skill ceiling in Endless Mode and is what separates Wave 75 BOSSes from Wave 85 BOSSes.

Treasure Wave Timing in Endless Mode

The Treasure Wave passive from Economy 4 doubles all wave rewards every tenth wave, and the timing matters more in Endless Mode than in any other phase. The optimal timing is to align your Treasure Waves with active events — the Gold Rush event, the Shattered Storm event, or the Cursed Moon event. A Treasure Wave during Gold Rush can exceed 500 coins, which is enough to fund a full skill tree node without skipping any other upgrade.

The Treasure Wave alignment is also useful for soul generation. During Shattered Storm, the soul rewards also double on Treasure Waves, which gives you a meaningful army expansion on top of the coin injection. The optimal play is to start your Endless Mode session during an active event, time your Treasure Waves to land at Wave 60, 70, 80, and 90, and queue into a fresh server immediately after the event starts.

Common Endless Mode Failure Modes

Five failure modes account for most Endless Mode collapses in Be The Final Boss:

• Soul starvation by Wave 55 — without Soul Discount, soul generation collapses below the resummoning threshold

• Castle HP below 50% by Wave 60 — without Castle Defense 4 plus armor stacking, the chip damage outpaces regen

• Doomfist death spiral — Doomfist dies and the BOSS cannot resummon due to soul starvation, which cascades into full line collapse

• Hero amplifier stacking — without minion spread, an amplifier stacks to 4x and boosts a single hero to deal 60% more damage

• Castle rusher overwhelm — without a back-line tank, castle rushers sprint directly to the castle and chip 8-12% HP per wave

Each failure mode has a specific counter, and most BOSSes collapse because they failed to plan for at least two of them simultaneously. The fix is to review the failure mode after each run, fund the missing counter through a focused grind, and retry the Endless push with the counter online.

The Endless Reset Decision

Skill tree resets in Endless Mode are higher-stakes than in standard waves because your investment is larger. A BOSS with 4,000+ coins invested loses 1,000+ coins on a reset, which is roughly 10-15 waves of rewards. The decision to reset should be based on the data — three or more Endless collapses at the same wave with the same failure mode justifies a reset, while a single collapse does not. The most common reset scenario is refunding Boss Power 2-3 to fund Soul Discount plus Castle Defense 4, which is the single most impactful Endless Mode pivot.

Frequently Asked Questions

What is Endless Mode in Be The Final Boss?

Endless Mode starts at Wave 51 after you clear the Wave 50 checkpoint boss. The mode continues until your castle falls, with hero count, hero tier rotation, and castle chip damage all scaling aggressively. The Endless Mode leaderboard resets weekly, and the top players typically reach Wave 80-90 in a single session. The mode is designed to test sustainable scaling rather than binary boss checks.

What is the highest wave in Be The Final Boss Endless Mode?

The current leaderboard top is roughly Wave 92, reached by a coordinated 6-player co-op squad with full armor system stacking from UPD2 and a balanced skill tree. Solo runs typically cap around Wave 75-80, while 6-player co-op can push past Wave 85 with proper coordination. The limit is set by the late-game scaling curve, which eventually overwhelms every defensive layer.

Do I need the UPD2 armor system for Endless Mode?

Yes, the armor system stacking from UPD2 is mandatory for any Wave 65+ push. The armor adds multiplicative HP and damage bonuses that compound with your skill tree nodes, transforming the late-game scaling curve from "I will fall at Wave 60" to "I will fall at Wave 80+". Without armor, your castle HP and weapon damage are roughly half of what they should be, and the late-game chip damage will collapse your run by Wave 60.

What is the best skill tree for Endless Mode?

The best Endless Mode skill tree is balanced across all four branches plus the Elite Minion Slot: Population 4, Castle Defense 4, Economy 4, Boss Power 3, Elite Minion Slot, and Soul Discount. Total investment is roughly 5,000 coins, which takes 6-8 weeks of regular play. The configuration is the minimum for a Wave 65 push and the foundation for any Wave 75+ attempt.

Should I play Endless Mode solo or in co-op?

Co-op is generally better for Endless Mode because six BOSSes can distribute lane pressure, share Doomfist resummoning duties, and synchronize Treasure Wave timing. Solo Endless is viable but requires tighter minion cycling and stricter skill tree discipline, with solo runs typically capping around Wave 75. Co-op runs regularly push past Wave 85 with proper coordination, especially during active events.
