Update 3 has made the best-unit question messier, not simpler
The strongest concrete takeaway from the current Be The Final Boss rankings is that the best unit on paper is often the wrong first investment. Pro Game Guides’ Update 3 list places Secret units such as Skull King, Demon Lord, and Doomfist at the top of its roster ordering, while Gamepur’s Update 3 guide argues that investment efficiency can push a cheaper unit ahead of a stronger max-level option. Its example is blunt: a max-level Demonic Skeleton Archer is described as slightly weaker than a max-level Demonic Grave Warlock, but Gamepur says it takes 25 times fewer materials to finish, making the Archer the better early upgrade target.
That tension is the whole Be the Final Boss tier list problem right now. Players are not only asking which minion has the highest ceiling. They are asking which pick will actually move their account forward before the grind stalls. The game, described by LDPlayer as a Roblox defense experience from Apparently Champions, revolves around summoning minions, defending a castle from hero waves, improving a permanent Skill Tree, and unlocking stronger boss weapons. In that structure, a unit that stabilizes your first routes and scales cheaply can be more valuable than a rare chase unit sitting underleveled in your roster.
The community wiki adds an important warning label: Be The Final Boss is in Early Access, balance changes frequently, and its tier placements are provisional rather than final meta doctrine. That is why this guide ranks practical first-use value ahead of theoretical prestige. If you are looking for Be the Final Boss best picks, start with units that solve a current failure point: a front line that collapses, backline damage that arrives too late, or grouped heroes that overwhelm single-target pressure.
How to read the current Be the Final Boss rankings
Across the available community guides, the most useful rankings judge four things: damage uptime, tanking reliability, support value, and cost. Gamepur says its list weighs DPS, HP, abilities, placement cost, and whether a unit is worth upgrading compared with units of the same or higher rarity. Pro Game Guides says its rankings consider endgame ceiling, Population efficiency, upgrade difficulty, and practical progression value, using Normal Level 1 base stats before mutation, level, Skill Tree, and account-wide bonuses. The community wiki similarly says its Early Access tiers consider wave clear speed, castle safety, currency efficiency, and accessibility for players without premium advantages.
Those criteria matter because Be The Final Boss is a progression game before it is a collection checklist. LDPlayer’s July ranking, which deliberately covered only six units it said were confirmed through available footage and guides, emphasized the same idea from an early-account perspective: a rare or advanced unit can still be awkward if its Soul cost or Population requirement prevents a full formation. That is a useful corrective to tier lists that rank only by rarity.
For a first-use Be the Final Boss guide, treat S tier as a direction, not an instruction to empty every resource immediately. If an S-tier Secret unit is unavailable or too expensive to upgrade, use a reliable A or B option in the role you need. The community wiki specifically cautions that copying a tier list without understanding the build can underperform, especially if a player neglects minions, weapons, or Skill Tree investment. In practice, the best early ranking question is not “what is the rarest unit I own?” It is “which affordable unit gives my formation one more clean wave?”
Best picks to use first for early and mid-game progression
For most players, Skeleton Archer is the safest first backline investment. Gamepur highlights the Demonic Skeleton Archer as a cost-efficient upgrade compared with Demonic Grave Warlock, while Pro Game Guides lists Skeleton Archer high among its Update 3 units despite its Uncommon rarity. LDPlayer also ranks Skeleton Archer in its top early group, calling it a dependable ranged unit that can attack from behind a melee line. The role is simple, but that is exactly why it works early: protect it, level it, and let it create consistent damage while sturdier units absorb contact.
Your first front-line priority depends on what you have unlocked. LDPlayer identifies Iron Skeleton as one of the safest early front-line investments among the units it verified, because it gives ranged units more time to work. Pro Game Guides places Mighty Orc much higher in its broader Update 3 ranking, and Gamepur’s ranking discussion gives a specific reason to respect it: Mighty Orc regenerates every two seconds regardless of combat, while Blood Gargoyle needs to take damage to heal, resulting in less overall healing according to Gamepur. If you have Mighty Orc, it is the better long-term tank target. If you do not, Iron Skeleton is the practical stabilizer.
After a basic tank and Archer line are working, add area or magical pressure. Pro Game Guides ranks Lava Imp high, ahead of several Legendary and Epic options, while LDPlayer highlights Imp Bomber as valuable when grouped heroes are the reason a defense fails. Gamepur’s available text also treats DPS-to-cost ratio as a major ranking factor, which supports the idea that early damage picks must justify their deployment and upgrade cost. Grave Warlock and Hellfire Warlock can become attractive backline projects, but Gamepur’s material-cost comparison makes Skeleton Archer the smarter first ranged upgrade unless your account is already feeding higher-rarity units comfortably.
Support units are easy to underrate because they do not look like carries
Deathlock is the support name to watch in the current rankings. Pro Game Guides places Deathlock near the top of its Update 3 list as a Mythic Support, below the Secret and Mythic front-line standouts but above many conventional damage units. Gamepur goes further in practical terms, saying some units such as Deathlock provide strong buffs and do not require upgrades or the Demonic mutation to be worthwhile. That is a major progression clue for players trying to stretch limited materials.
Support value scales with formation size. Gamepur states that the more units you can deploy, the more valuable a few Deathlocks become. That means Deathlock is not necessarily the first thing a brand-new account should force if it cannot yet field a meaningful army around the buff, but it becomes a very efficient addition once your frontline and backline core are already functioning. In RPG terms, it is the difference between equipping a damage aura before you have damage dealers and adding it once the party has a real rotation.
Necromancer, Soul Collector, and Cursed Acolyte appear in Pro Game Guides’ ranking as support units at lower positions than Deathlock. The source material provided does not give enough detailed ability text to claim exact best use cases for each, so the safer advice is role-based: do not overinvest in secondary support until your formation’s survival and damage problems are solved. If Deathlock is available, it has the clearest cross-source argument as an efficient support pickup. If it is not, treat other supports as build-specific rather than automatic upgrades.
Late-game chases: Skull King, Doomfist, Demon Lord, and Demon Butcher
Once your early economy can sustain real upgrades, the chase list changes. Pro Game Guides puts Skull King, Demon Lord, and Doomfist at the top of its Update 3 ordering, with Skull King and Demon Lord marked as Secret Guards and Doomfist as a Secret Melee unit. It also ranks Mighty Orc and Deathlock immediately after those Secret picks, followed by Skeleton Archer, Lava Imp, Hellfire Warlock, and Demon Butcher in its displayed order. The community wiki’s Early Access S tier also names Doomfist, Mighty Orc, Skull King, Demon Butcher, Shiny Lava Imp, Iron Skeleton, and Bloody Gargoyle as dominant options, while noting that its placements change when consensus shifts among high-wave players or when developers communicate balance intentions.
Skull King has the clearest documented tank profile in the provided material. Pro Game Guides lists its Normal Level 1 base stats as 450 ATK, 5,850 HP, 6 Range, and 4 Cost, with an active heal called Deep Recovery that restores 40 percent of max HP and a passive called Pain Recovery that restores HP when taking damage. Pro Game Guides’ evaluation calls it the best pure wall in the roster, but also says Secret rarity, 4 Cost, and heavy upgrade demands make it a late-game project rather than a sensible first chase.
That caveat should shape your Be the Final Boss rankings more than the tier label alone. Doomfist and Demon Lord may sit at the top of Update 3 lists, but the available sources do not provide enough complete detail here to recommend them as early resource dumps for every player. Demon Butcher is another high-end melee name that appears strongly in Pro Game Guides and the community wiki. The sensible path is to build toward these units while keeping your cheaper core productive, rather than freezing progression while waiting for a Secret pull or unlock.
Where the community lists disagree, and how to protect your resources
The biggest visible disagreement concerns gargoyle-style tanks. Gamepur’s ranking explanation says Mighty Orc heals more reliably than Blood Gargoyle because Orc regeneration occurs every two seconds regardless of combat, while Blood Gargoyle must take damage to heal. Pro Game Guides places Blood Gargoyle below several mid-tier units in its displayed ordering. The community wiki, however, lists Bloody Gargoyle among its Early Access S-tier options. Those may refer to naming, mutation, or balance-context differences, but the provided sources do not resolve that conflict. Until more specific data is available, treat Gargoyle investment as disputed rather than universally safe.
There is also a timing conflict in the guide ecosystem. Pro Game Guides’ page is titled around Update 3, but one paragraph in the provided text says “Update 2 Be The Final Boss tier list,” even though the surrounding article discusses Update 3 and includes Doomfist among the top units. LDPlayer’s July 23 ranking was intentionally narrower, covering only six units and excluding Update 1 additions until names and abilities could be verified accurately. The community wiki says rankings are Early Access and based on testing, high-wave evidence, and shifting consensus. None of that makes the guides useless. It means players should separate confirmed role value from unsettled tier exactness.
The most reliable resource rule comes from the overlap between sources: avoid pouring Souls into low-impact starters once they have served their opening purpose, but do not skip functional B-tier or A-tier units while waiting for an S-tier fantasy. The bethefinalboss.wiki guide frames Coins as Skill Tree fuel and Souls as army recruitment currency, while Gamepur’s mutation note says usually only Demonic units are worth getting, with exceptions for low-rarity Cursed units and some supports. Read that as a warning against shallow collecting. A focused roster beats a crowded bench.
A practical first-build order for Update 3 players
If you want a simple Be the Final Boss best picks order, build from the path outward. Start with Skeleton Archer as your efficient ranged backbone, especially if you can pursue its Demonic version. Pair it with the best front-line holder available to your account: Iron Skeleton for early stability, Mighty Orc when you can access and upgrade it, and Skull King only when its rarity and cost no longer starve the rest of your formation. Add Lava Imp or Imp Bomber when grouped enemies, rather than single durable heroes, are causing your losses. Bring in Deathlock once you have enough deployed units for its support value to matter.
After that, your chase priorities should be shaped by unlocks and upgrade materials. Doomfist, Demon Lord, Skull King, and Demon Butcher are the names most associated with high-end community rankings in the current source set, but they are long-term goals. Hellfire Warlock and Grave Warlock can fit developed backlines, yet Gamepur’s comparison between Skeleton Archer and Grave Warlock is the clearest argument against rushing a costlier caster too early. If a unit cannot be leveled, mutated, or supported by your Skill Tree, its tier-list rank will not save a weak defense.
For players checking a Be the Final Boss tier list after every patch, the patient approach is the strongest one. Use community rankings to identify efficient roles, then spend around the bottleneck that is actually ending your runs. If your melee line dies, upgrade the tank. If heroes reach the castle with low health, increase ranged damage. If clusters flood the lane, add area pressure. Update 3’s best picks are not a single roster copied from a chart. They are a sequence of investments that keeps your castle alive while your account grows into the expensive units everyone wants.
