Changes

Bloon sends

“

Even after the nerfs in the last balance patch, Tight Ceramics are still proving to be one of the most dangerous rushes in the game. We’re spacing them out a little more in order to make it easier for defenses to handle them. — Update notes

”

•  Tight Ceramics: Total send time increased ― 1s → 1.2s
  • Note: Bloon delay increased from 0.025s to 0.03s

Bomb Shooter

“

Cluster Bombs is already a potent weapon against grouped bloons, especially when map blockers allow multiple explosions to hit the same bloon. We don’t feel like it needs any extra power so we are reducing the extra pierce gained from crosspathing. — Update notes

”

Tiers	Changes
1-0-3 Cluster Bombs + Bigger Bombs 1-0-4 Recursive Cluster + Bigger Bombs 1-0-5 Bomb Blitz + Bigger Bombs	Cluster: pierce bonus decreased ― +6 → +4 Note: Total pierce decreased from 14 to 12
2-0-3 Cluster Bombs + Heavy Bombs 2-0-4 Recursive Cluster + Heavy Bombs 2-0-5 Bomb Blitz + Heavy Bombs	Cluster: pierce bonus decreased ― +6 → +4 Note: Total pierce decreased from 20 to 16

Ice Monkey

“

Snowstorm is still an extremely effective stalling tactic, even with last update’s nerfs. We are increasing its price further in order to make it less efficient to micro. — Update notes

”

Tiers	Changes
X-4-X Snowstorm	Upgrade cost increased ― $3,500 → $4,000

Sniper Monkey

“

This was buffed in a previous update, but it has been performing better than we thought it would. So this should bring its performance to where we want it. — Update notes

”

Tiers	Changes
X-3-X Bouncing Bullet	Upgrade cost increased ― $2,250 → $2,600

Heli Pilot

“

The Heli Pilot’s bottom path tier 5s often feel weaker than those of other towers so we are giving it a small buff to help it out. In addition, we are nerfing MOAB Shove slightly because its stall was too cost effective**.** [sic] — Update notes

”

Tiers	Changes
X-X-3 MOAB Shove	Upgrade cost increased ― $3,700 → $4,000
X-X-5 Comanche Commander	Upgrade cost reduced ― $35,000 → $34,700  Mini-Comanche Dart: Attack cooldown reduced ― 0.15s → 0.13s

Mortar Monkey

This article is in need of research. You can help out by editing this article or discussing your findings on the talk page. The editor who added this notice elaborates: Does the +20 main explosion pierce carry into Biggest One? Does the stun and shockwave pierces by +15 pierce carry into Biggest One? Does the +4 blast radius carry over into Shell Shock, Big One, and Biggest One?

“

The Big One was feeling overshadowed by Artillery Battery in situations with large amounts of bloons. These pierce buffs should help it shine in these situations. [...] This buff will improve the mortar’s strength as damaging tower. — Update notes

”

Tiers	Changes
1-X-X Bigger Blast 2-X-X Bloon Buster	Blast radius increased ― 26 → 30 Note: Blast radius bonus increased from +8 to +12  Pierce increased ― 40 → 45 Note: Pierce bonus increased from +5 to +10
4-X-X The Big One	Main explosion: Pierce increased ― 80 → 100  Stunwave: Pierce increased ― 85 → 100  Shockwave: Pierce increased ― 85 → 100

Wizard Monkey

“

This upgrade was a little bit too cheap for its power, this should nerf the early game a little while still keeping it viable. — Update notes

”

Tiers	Changes
3-X-X Arcane Mastery	Upgrade cost increased ― $1,200 → $1,300

Ninja Monkey

“

The recent shinobi nerf made the Grandmaster Ninja a little underpowered. This should bring it back in line. Like the Grandmaster Ninja, the Master Bomber is also now a little underpowered. This buff should help it feel more consistent like it used to. — Update notes

”

Tiers	Changes
5-X-X Grandmaster Ninja	Shuriken: Damage increased ― 2 → 4
0-X-5 Master Bomber	Shuriken: Attack cooldown reduced ― 0.434s → 0.385s Note: Flash Bomb (3rd shuriken shot) cooldown decreased from 1.302s to 1.155s
1-0-5 Master Bomber + Ninja Discipline 2-0-5 Master Bomber + Sharp Shurikens	Shuriken: Attack cooldown reduced ― 0.62s → 0.55s Note: Flash Bomb (3rd shuriken shot) cooldown decreased from 1.86s to 1.65s

Banana Farm

“

Monkeynomics is underperforming after the x4x IMF Loan nerf. This should bring it back in line with how it was pre nerf. [...] This change will hopefully add a bit more identity to the bottom path, setting it apart from the other 2. — Update notes

”

Tiers	Changes
X-5-X Monkey-Nomics	Ability cooldown decreased ― 50s → 40s Note: Initial cooldown remains 30s
X-X-2 Banana Salvage	Sellback bonus decreased ― +10% → +5% Note: Marketplace and above unchanged (+10%)

Biker Bones

This article is in need of research. You can help out by editing this article or discussing your findings on the talk page. The editor who added this notice elaborates: Does cooldown nerf to concussive affect the lvl that further decreases cooldown of the shell?

“

Biker Bones is very strong with late game strategies. This nerf to his earlier game will make him weaker early game to balance out his late game strength. Additionally we are introducing a new synergy with the buccaneer to vary his playstyles. — Update notes

”

Levels	Changes
3+	Concussive Blast: Ability cooldown increased ― 24s → 30s
7+	Flame Trail: Pierce reduced ― 4 → 2  Flame Trail: Now affects the fighter planes of Aircraft Carrier and Carrier Flagship

Pat Fusty

“

We are making this change to make Pat’s slaps more consistent, without reducing his DPS. — Update notes

”

Levels	Changes
5+	Slap: activations per slam increased ― 5th attack → 3rd attack  Slap: Knockback duration decreased ― 1s → 0.5s  Slap: Area-of-effect damage increased ― 0 → 2

Fusty the Snowman

“

We are changing this for the same reason as Pat’s, but the dps on Fusty the Snowman is already good so reducing amount ice shards will keep the dps as it was before. — Update notes

”

Levels	Changes
5+	Slap: activations per slam increased ― 5th attack → 3rd attack  Slap: Knockback duration decreased ― 1s → 0.5s  Slap: Shard amount when hitting Frozen Bloons decreased ― 6 → 3

DJ Benjammin'

“

DJ Ben has been performing quite strongly in the current meta, so we’re making some adjustments to bring him more in line with other options. — Update notes

”

Levels	Changes
1+	End-of-round income: Sub-towers (e.g. Sentry Gun) no longer count for income stacks
4-10	Pierce buff to nearby towers decreased ― +1 → +0
11+	Pierce buff to nearby towers decreased ― +2 → +1
5-8	Side Hustle: Income buff decreased ― +6% → +3%
9+	Side Hustle: Income buff decreased ― +9% → +6%
14+	Encore: Reduced ability cooldown buff decreased ― 15% → 10%

Etienne

This article is in need of research. You can help out by editing this article or discussing your findings on the talk page. The editor who added this notice elaborates: Confirm if the targeting buff changes only the main drones (does it affect drone swarm and ucav?)

“

We thought it would be fun to add to Etienne's playstyle by incorporating his targeting options into his damage output. — Update notes

”

Levels	Changes
1-3	Pierce increased ― 2 → 3 Note: Level 4–11 remains the same (3)
4+	Now unlocks Zone Defense at level 4  Targeting priorities now provide different stat bonuses for the main drones Divide and Conquer: +20 movement speed and +10% attack speed Zone Defense: +1 damage First: +1 pierce (+2 pierce at level 9+)

Beetienne

“

Defend the hive was a little overpowered. This should bring it back in line. — Update notes

”

Levels	Changes
3+	Defend the Hive: Speed modifier decreased ― 2× → 1.33×
