Picking the best BOSS weapon in Be The Final Boss depends on your wave range, your hero composition, and your skill tree investment. While the Tempest is universally the strongest Tier 5 option, not every BOSS can afford it, and many wave compositions are better served by cheaper weapons. This best BOSS weapons tier list ranks the top 10 weapons in the UPD2 patch from S to C, with specific wave-range recommendations and play-style notes. Use it to choose your main weapon upgrade path and rotate to alternative weapons only when the wave composition demands it.
The weapon meta has shifted three times since launch: the UPD1 patch favored single-target weapons because the hero roster was mostly single-target threats. The UPD2 patch favors multi-target weapons because of the introduction of clustered hero waves. Endless Mode favors AOE weapons because the wave density scales linearly with wave number. Future patches will likely shift the meta again, but the underlying principles — focus on a single main weapon, match damage type to wave composition, reserve ammo for priority heroes — remain stable.
Top 10 BOSS Weapon Tier List (UPD2, July 2026)
The tier list below ranks the 10 most-used BOSS weapons by their effectiveness across the typical wave range where they appear. S-tier weapons are encounter-defining choices that should be the main weapon for any BOSS who can afford them. A-tier weapons are strong options that work well in most wave compositions. B-tier weapons are situational picks that solve specific problems. C-tier weapons are niche options that work only in very specific compositions.
| Rank | Weapon | Tier | Damage Type | Tier List |
|---|---|---|---|---|
| 1 | Tempest | 5 | Multi-target | S |
| 2 | Cataclysm | 5 | AOE | S |
| 3 | Void Sovereign | 5 | Single-target | S |
| 4 | Meteor | 4 | AOE | A |
| 5 | Arclight | 4 | Multi-target | A |
| 6 | Voidcleaver Mk2 | 4 | Single-target | A |
| 7 | Stormbringer | 2 | Multi-target | B |
| 8 | Pyroclast | 3 | AOE | B |
| 9 | Frostbite | 2 | Single-target | B |
| 10 | Voidcleaver | 3 | Single-target | C |
S-Tier Weapons: The Absolute Best
The three S-tier weapons are the Tempest, Cataclysm, and Void Sovereign, all of which are Tier 5 weapons available at Wave 40+. Each one is the strongest weapon in its damage type and should be the main weapon for any late-game BOSS. The Tempest is the most versatile because it combines chain lightning with AOE, the Cataclysm is the strongest AOE option because of its massive radius, and the Void Sovereign is the strongest single-target option because of its execute + cleave combination.
| S-Tier Weapon | Strength | Weakness | Recommended BOSS |
|---|---|---|---|
| Tempest | Multi-target + AOE hybrid | Long cooldown | Endless Mode pushers |
| Cataclysm | Largest AOE radius in game | Slow fire rate | Late-game AOE focus |
| Void Sovereign | Execute + cleave | Wastes damage on low-HP | Late-game single-target focus |
A-Tier Weapons: Strong and Reliable
The three A-tier weapons are Meteor, Arclight, and Voidcleaver Mk2, all of which are Tier 4 weapons available at Wave 25+. Each one is a strong option that works well in most wave compositions but is slightly less universal than the Tier 5 options. The Meteor is the strongest pre-Tier-5 AOE option, the Arclight is the strongest pre-Tier-5 multi-target option, and the Voidcleaver Mk2 is the strongest pre-Tier-5 single-target option.
| A-Tier Weapon | Strength | Weakness | Recommended BOSS |
|---|---|---|---|
| Meteor | Strong AOE before Tier 5 | Outclassed by Cataclysm | Mid-to-late game AOE |
| Arclight | Strong multi-target before Tier 5 | Outclassed by Tempest | Mid-to-late game multi-target |
| Voidcleaver Mk2 | Strong single-target before Tier 5 | Outclassed by Void Sovereign | Mid-to-late game burst |
B-Tier Weapons: Situational Picks
The three B-tier weapons are Stormbringer, Pyroclast, and Frostbite, which are mid-game weapons available at Wave 5-15. Each one is a strong situational pick that solves a specific problem but is outclassed by Tier 4+ weapons in their damage type. The Stormbringer is the best budget multi-target weapon, the Pyroclast is the best budget AOE weapon, and the Frostbite is the best budget single-target weapon with utility.
| B-Tier Weapon | Strength | Weakness | Recommended BOSS |
|---|---|---|---|
| Stormbringer | Cheapest multi-target | Outclassed by Arclight + Tempest | Early-to-mid game BOSSes |
| Pyroclast | Cheapest AOE | Outclassed by Meteor + Cataclysm | Budget AOE BOSSes |
| Frostbite | Slow utility | Outclassed by Voidcleaver | Slow-focused play |
C-Tier Weapons: Niche Options
The C-tier weapon on this list is the Voidcleaver, a Tier 3 single-target weapon that is largely outclassed by Tier 4 single-target options. It remains useful in builds that want to reach Tier 3 quickly without committing to a Tier 4 weapon path, but most BOSSes should save their coins for a Tier 4+ weapon instead.
Best Weapon by Wave Range
Different weapons excel in different wave ranges. The matrix below matches the most common wave compositions to the recommended weapon. Adjust based on your coin wallet, but the damage type match should remain similar.
| Wave Range | Recommended Weapon | Damage Type | Why |
|---|---|---|---|
| 1-5 | Blaster | Single-target | Balanced starter weapon |
| 6-10 | Stormbringer | Multi-target | Handles Berserker + Scout |
| 11-15 | Stormbringer (Tier 2) | Multi-target | Handles Aura Mage + Knight |
| 16-20 | Arclight (Tier 3) | Multi-target | Handles Phantom Assassin |
| 21-25 | Arclight (Tier 4) | Multi-target | Handles Siege Golem support |
| 26-30 | Void Sovereign | Single-target | Handles Siege Golem burst |
| 31-40 | Tempest | Multi-target | Handles clustered Endless waves |
| 41-50 | Tempest (Tier 5) | Multi-target | Endless Mode meta |
| 50+ | Cataclysm | AOE | Maximum radius for high-density waves |
Early Game Best Weapons (Waves 1-10)
The early-game best weapon is the Blaster because of its balanced firing rhythm and forgiving ammo economy. The Cannon and Zapper are situational picks for damage-focused or AOE-focused play, but the Blaster is the most universal option for new BOSSes. Once you reach Wave 5 and unlock the Tier 2 weapon slot, switch to the Stormbringer for its multi-target damage that handles the Wave 6-10 hero roster efficiently.
Mid Game Best Weapons (Waves 11-25)
The mid-game best weapon is the Stormbringer upgraded to Tier 2, which deals 1.8x the damage of the starter Blaster and adds the chain lightning ability. The Stormbringer handles the Wave 11-20 hero roster with ease, and the chain lightning ability is the right counter for the Storm Knight's stun threat. By Wave 25, switch to the Arclight Tier 4 multi-target weapon, which is the strongest pre-Tier-5 option and handles the Siege Golem's support wave composition.
Late Game Best Weapons (Waves 26+)
The late-game best weapon is the Tempest Tier 5 multi-target weapon, which is the strongest weapon in the game and the foundation of every Endless Mode build. The Tempest's chain lightning + AOE hybrid damage handles the high-density Wave 30+ waves with ease, and the long cooldown is mitigated by the high per-shot damage output. For pure AOE focus, the Cataclysm is the alternative S-tier pick with the largest radius in the game.
Best Weapons for Specific Wave Compositions
Some wave compositions reward specific weapons more than the generic ranking suggests. The table below matches the most common late-game wave compositions to the recommended weapon choice. Use this matrix when you need to switch weapons for a specific wave.
| Wave Composition | Recommended Weapon | Why |
|---|---|---|
| Lots of melee heroes | Void Sovereign | Execute + cleave deletes clustered melee |
| Lots of ranged heroes | Arclight | Chain lightning pierces line of sight |
| Multiple buff heroes | Cataclysm | Massive AOE hits every buff target |
| Siege Golem wave | Tempest | Chain + AOE whittles down Golem |
| Phantom Assassin wave | Arclight | Chain lightning catches Assassin mid-flight |
| Storm Knight wave | Tempest | AOE damage kills before stun triggers |
Weapon Choice vs Hero Type
Some heroes are countered more effectively by specific weapons. The Aura Mage is best countered by the Tempest (chain lightning catches her at long range). The Siege Golem is best countered by the Void Sovereign (execute + cleave whittles his HP). The Healing Cleric is best countered by the Cataclysm (massive AOE kills her and her wave simultaneously). The Phantom Assassin is best countered by the Arclight (chain lightning catches her mid-crit).
Weapon Upgrade Order for Maximum Efficiency
The right weapon upgrade order is to focus on a single main weapon rather than spreading coins across multiple weapons. The recommended order is Stormbringer → Arclight → Tempest, which is the multi-target upgrade path that handles every wave composition. Spend 500 coins on the Tier 2 Stormbringer at Wave 5, then 1,500 coins on the Tier 3 Stormbringer at Wave 15, then 3,500 coins on the Tier 4 Arclight at Wave 25, then 8,000 coins on the Tier 5 Tempest at Wave 40.
| Upgrade Step | Wave | Coin Cost | Cumulative | Weapon |
|---|---|---|---|---|
| Starter | 1 | 0 | 0 | Blaster |
| Tier 2 unlock | 5 | 500 | 500 | Stormbringer |
| Tier 3 unlock | 15 | 1,500 | 2,000 | Stormbringer |
| Tier 4 unlock | 25 | 3,500 | 5,500 | Arclight |
| Tier 5 unlock | 40 | 8,000 | 13,500 | Tempest |
Total Coin Investment
The full multi-target weapon upgrade path requires 13,500 coins total, which is roughly the coin income of a typical Wave 40 run. New BOSSes cannot afford this on their first attempt; build it incrementally across multiple runs. The cheapest fully-functional mid-game weapon setup costs around 2,000 coins using the Stormbringer at Tier 3.
When to Pivot Weapons
Pivoting weapons is worthwhile when the current weapon's damage type no longer matches the wave composition. If you are facing the Siege Golem with a single-target weapon, switch to an AOE weapon only if the wave composition has multiple priority heroes. If you are facing clustered waves with a single-target weapon, switch to an AOE or multi-target weapon as soon as the wave composition shifts. The switch should be temporary — switch back to your main weapon once the wave composition returns to normal.
Weapon Comparisons by Damage Type
The three damage types — single-target, multi-target, and AOE — each have their own internal ranking. The tables below show the strongest weapon in each damage type, plus the runner-up and budget options.
Single-Target Weapons Ranked
Single-target weapons are best for high-HP priority heroes like the Siege Golem. The Void Sovereign is the strongest, followed by the Voidcleaver Mk2 and Frostbite. Save your single-target ammo for the Siege Golem and other checkpoint bosses rather than spending it on every wave.
| Rank | Weapon | Tier | Damage | Best Use |
|---|---|---|---|---|
| 1 | Void Sovereign | 5 | 9.0x | Siege Golem + checkpoints |
| 2 | Voidcleaver Mk2 | 4 | 5.5x | Mid-to-late game single-target |
| 3 | Frostbite | 2 | 1.8x | Budget single-target + slow |
| 4 | Voidcleaver | 3 | 3.2x | Pre-Tier-4 single-target |
Multi-Target Weapons Ranked
Multi-target weapons are the most versatile damage type and handle the largest variety of wave compositions. The Tempest is the strongest, followed by the Arclight and Stormbringer. The multi-target damage type is the recommended main weapon path for most BOSSes.
| Rank | Weapon | Tier | Damage | Best Use |
|---|---|---|---|---|
| 1 | Tempest | 5 | 9.0x | Endless Mode + late game |
| 2 | Arclight | 4 | 5.5x | Mid-to-late game multi-target |
| 3 | Stormbringer | 2 | 1.8x | Budget multi-target |
AOE Weapons Ranked
AOE weapons are best for high-density clustered waves. The Cataclysm is the strongest, followed by the Meteor and Pyroclast. AOE weapons are the second-most popular main weapon path after multi-target, particularly for BOSSes who focus on clearing clustered waves quickly.
| Rank | Weapon | Tier | Damage | Best Use |
|---|---|---|---|---|
| 1 | Cataclysm | 5 | 9.0x | Maximum AOE radius |
| 2 | Meteor | 4 | 5.5x | Pre-Tier-5 AOE |
| 3 | Pyroclast | 3 | 3.2x | Budget AOE |
