One Monkey MOAB demolition machine.
~ In-game description

Master Bomber is the fifth upgrade in Path 3 for the Ninja Monkey in Bloons TD 6. The upgrade enhances all of its bombs to become much stronger, especially versus MOAB-class bloons. New special sticky bombs are thrown every 4.5s from anywhere on screen, barring Line of Sight blockers, dealing 3,000 damage instead of 450 damage, and secondary sticky bomb explosions deal 600 damage instead of 100. Not only do its sticky bombs deal extra damage, sticky bombs stun affected MOAB-class bloons for up to 1.0s, while its flash bombs deal 10 damage and stun MOAB-class for up to 0.325s or standard bloons for 1.3s. The Counter-Espionage (0-2-5) crosspath will cause DDTs to lose camo as soon as the Sticky Bomb is attached, the secondary sticky bomb explosion will not remove camo, but can have a chance to blowback bloons. Additionally, it increases damage of its caltrops from 1 to 5 and an extra +5 for Ceramics. Shurikens now deal +9 damage against stickied & stunned targets.

This upgrade costs $34,000 on Easy, $40,000 on Medium, $43,200 on Hard, and $48,000 on Impoppable.

The Ninja Monkey dons a black Japanese oni mask. Its left hand holds a shuriken while its right hand holds a glue-soaked sticky bomb. The monkey also has bionic hands, each hand with a blue button each.

Master Bomber doesn't add any new attacks, instead improving the flash bomb, sticky bomb, and caltrops attacks. Stickies from Master Bomber are considered separate to normal stickies from its previous upgrade. Master Bomber stickies are marked by a less gluey sticky bomb colored black.

Each sticky bomb does 3,000 damage, enough to taking out Fortified BFBs and lower (but not the Bloons inside). The flash bomb attack deals 10 damage and also stuns MOAB-class for 0.325s, and bloons for 1.3s as usual, onto up to 30 bloons. Additionally, it increases damage of its caltrops from 1 to 5 and an extra +5 for Ceramics. Shurikens deal even more damage to stunned and stickied targets, for +9 from both sources of bonus damage.

Targeting Priorities[]

Master Bomber targets bloons using the standard targeting priorities. Its main attack shoots straight movement projectiles.

  • First: Targets the first bloon visible within its range.
  • Last: Targets the last bloon visible within its range.
  • Close: Targets the closest bloon visible within its range.
  • Strong: Targets the strongest bloon visible within its range.

Both shurikens and Flash Bombs are shot in a straight movement, and follow targeting of the Ninja. Sticky Bombs are shot in a straight movement, follow targeting of the Ninja at full map range, and only target MOAB-class bloons. Caltrops are locked on Normal targeting priority, which dispenses the caltrops onto nearby bloon track in a semi-sporadical behavior.

All Ninja Monkeys can access Camo Prioritization. While Camo Prioritization is active, it allows all its attacks to prioritize Camo Bloons over other types.

Master Bomber specializes at handling blimps, especially stronger blimps. Unlike Grandmaster Ninja, Master Bomber is somewhat decent on its own, as it provides adequate stunning power versus MOAB-class bloons, although pairing with Shinobi Tactics is strongly recommended to maximize its group-popping power, much like the Grandmaster. Compared to Grandmaster, Master Bomber is superior at dealing with clusters of MOAB-class bloons and single-targets, does not require as much support, but costs more overall. Its previous upgrade is quite expensive as well.

Positioning is far more important for Master Bomber to truly maximize its potential. Unlike Grandmaster, who has a seeking crosspath for its powerful attacks, Master Bomber instead requires a different set of conditions to optimize its anti-blimp power. Ideally, place a Master Bomber where max Shinobi spam can be utilized while also ensuring that the Master Bomber can keep both consistent sticky bomb angles and utilize bends for its blimp-stunning Flash Bombs. And lastly, clear Line of Sight is key, so try letting its infinite-ranged sticky bombs reach as much range as possible while still keeping a low enough range to avoid missing important targets.


  • It is recommended to purchase Ninja Discipline as well when purchasing the Master Bomber because it will make it overall shoot faster, including the rate at which bombs are thrown. The immense power of the bombs alone outweigh the power of its shurikens, so it is not worth purchasing the Path 2 upgrades (Distraction and Counter-Espionage), especially because only one Master Bomber may ever be on the track at one time. However, if overall camo defense is lacking then the sticky bombs can strip the camo property off DDTs.
  • Despite its slow attack speed with the bombs, it can still reliably destroy MOABs and DDTs effectively, only if placed in a spot with lots of vision.
  • The Master Bomber's Sticky Bombs have infinite range but involves Line of Sight. It is a good idea to plan placement for the Master Bomber so that the travel time for each sticky bomb projectile is decreased. Placing on high ground is additionally a good idea, so that the sticky bombs do not fail to land.
  • It is also advised to spam Shinobi Tactics ninjas around the Master Bomber, because it will increase its Sticky Bombs firing rate, increase stun uptime via the Flash Bombs, and further improves pierce of all its attacks. If there are enough Shinobis, it can throw out Sticky Bombs at hypersonic speed, which makes it live up to its name as a "Monkey MOAB Demolition Machine".
  • Round 98 can be beaten with ease with Master Bomber and 20 nearby Shinobi Tactics, thanks to its high damage and decent grouped popping of stronger grouped bloons. Use a map where Shinobis can be spammed and where Master Bomber can throw stickies at consistent angles.
  • Ground Zero and similar can pair well with Master Bomber, with the bomber set to Strong defeating stronger blimp layers and the Ground Zero ability eliminating leftover MOABs or below.
  • Although Master Bomber's Sticky Bombs have infinite range, it is best to place Master Bomber around a bend to make the most of its Flash Bomb stuns versus MOAB-class bloons. This will help clump the blimps up, especially noticeable when paired with many Shinobis.
  • Note that the Master Bomber's secondary sticky bomb explosion cannot hit the same blimp that the sticky bomb projectile was attached to. Therefore, the sticky bomb will always deal 3,000 damage to single-target blimps. That is still excellent against single-target blimps, even BADs and Bosses.
  • Unlike Sticky Bomb, Strong is even more preferable, since the Master Bomber’s stickies deal so much damage that it wipes out ZOMG layers very quickly while doing massive collateral damage surrounding other blimps. Otherwise the slow stickies get wasted on weak blimps, defusing them if the blimps are destroyed too fast.
  • Try to position a Master Bomber such that it can utilize its Flash Bombs along a clear tight area.

Version History[]

Balance Changes[]

Master Bomber has received a price buff, an added stun versus blimps, and extra Flash Bomb damage, and secondary sticky bomb explosions, which all should improve its anti-MOAB potential at a more cost-effective price. Version 39.0 reworked Master Bomber after patching sticky stacking in 38.1, compensating its otherwise very low single-target damage.

  • BUFF Cost of Master Bomber decreased ($60,000 → $40,000)
  • BUFF Master Bomber's Sticky Bomb attack now stuns MOAB-class Bloons for 1 second upon impact.
  • BUFF Flash Bomb now stuns MOAB-class bloons for 0.25 seconds.
  • BUFF Flash Bomb damage increased (1 → 5)
  • Change Now correctly applies stun art.
To try and allow more strategic use Ninja's Sticky Bombs will now use the targeting of the main tower instead of always Strong. Additionally as they weren't feeling good enough in general Sticky Bombs will now deal a smaller amount of damage in an AoE to anything surrounding the main target.
~ Ninja Kiwi
  • Change Master Bomber sticky bombs are no longer always on Strong. They are thrown with a similar targeting priority to the ninja itself.
  • BUFF Master Bomber sticky bombs now create an additional 300-damage explosion with 10 pierce and a radius of 40.
As ninja is the 'Camo Specialist' and has been since inception, it is the only tower that will unlock Camo Prioritization on the base tower. Master Bomber's main flash bomb has also been buffed in damage slightly leading into the new Ninja Paragon.
~ Ninja Kiwi
  • BUFF Affected by base Ninja Monkey, by gaining natural Camo Prioritization target option
  • BUFF Master Bomber Flash Bomb damage increased from 5 → 10
  • BUFF Affected by Distraction providing distraction to Caltrops and Flash Bomb
Ironing out Caltrop inconsistency & power a little on top and bottom T5s, but also as frequently unused caltrops clutter up the screen and cause extra lag we want to balance out their lifespan to reduce the number always on screen and make them no longer last longer than the base Spike Factory. [...]
~ Ninja Kiwi
  • NERF Master Bomber's Caltrops lifespan reduced from 70s → 35s
  • BUFF Master Bomber's Caltrops damage increased 1 → 5
  • BUFF Master Bomber's Caltrops gain +5 Ceramic damage on top
  • BUFF Master Bomber base range increased (40 → 55)
  • NERF Multiple Master Bomber’s sticky bombs thrown in quick succession will no longer stack extra sticky bombs on the same target
Flash Bomb’s long time between bombs, without improvements on the main attack leaves this as quite a bad stepping stone, for now due to this long downtime we want to try increasing the stun duration. The recent bug fix for xx4 Sticky Stacking ended up hurting Master Bomber’s viability as it was relying on that bug to have any real single target impact, now that it can be balanced with intended functionality we’re trying out much higher damage per explosion with slower attacks for single target performance as it has Shinobi synergy to bring this rate back up.
~ Ninja Kiwi
  • BUFF Master Bomber's Flash Bomb stun duration versus bloons increased (1s → 1.3s)
  • NERF Master Bomber sticky attack rate reduced (2s → 5s)
  • BUFF Master Bomber sticky damage increased (1000 → 3000)
  • BUFF Master Bomber sticky AoE damage increased (300 → 600)
Flash Bomb has pierce too excessive for Shinobi Tactics to do anything for it but then lacks any actual damage output, so this high pierce is trading in for greater damage. Master Bomber’s MOAB stun was not changed when Flashbomb stun duration was previously increased, so it is now increasing to match
~ Ninja Kiwi
  • BUFF Master Bomber's flash bomb MOAB-class stun time increased from 0.25s to 0.325s
  • NERF Master Bomber's flash bomb pierce decreased from 60 to 30
Bottom path Ninja never does anything with the main shuriken projectile past the xx1 upgrade leaving it inconsequential on higher tiers. Given that Flash Bombs can feel lacking without heavy support, we’re trying out a change that makes Flash Bomb Ninja scale better with attack speed and pierce as something of a combo-attacker. Overall, this feels pretty ‘right’ for ninjas and more importantly it’s cool and sometimes that’s what matters most
~ Ninja Kiwi
  • BUFF Master Bomber main Shuriken attack now deals +9 damage to stunned bloons
  • BUFF Master Bomber main Shuriken attack now deals +9 damage to stickied bloons
  • Change Indirectly buffed, as Sticky Bomb's impact deals 50 less damage but doesn't carry over to Master Bomber
While a great early game option, Ninja generally struggles with dominant crosspathing choices and also has relatively poor base tower value. Without going into every single change, T3s onward remain relatively unchanged with a lot of prices below T3 being moved around from less favorable crosspaths into better/higher tier upgrades. [...]
~ Ninja Kiwi
  • BUFF Master Bomber base shuriken attack cooldown reduced from 0.7s to 0.62s, 4th shot attack cooldown for flash bomb reduced from 2.8s to 2.48s. Does not affect 1-0-5 (0.434s, 1.68s).
  • BUFF Master Bomber attack cooldown of caltrops reduced from 4.4s to 3.9s
  • NERF 1-0-4 Master Bomber attack cooldown of caltrops increased from 2.728s to 2.73s
  • BUFF Master Bomber base attack cooldown of sticky bomb reduced from 5s to 4.5s.
  • NERF 1-0-5 Master Bomber base attack cooldown of sticky bomb reduced from 3.1s to 3.15s.

Extra Notes (Version History)[]


When attaching a Sticky Bomb on a MOAB-class bloon:


Official artwork[]



  • Since Master Bomber immediately throws a bomb on being upgraded, it is possible to have a sticky bomb get placed on a Ceramic Bloon if an x-x-4 Ninja is upgraded to x-x-5 such that the first sticky bomb pops the MOAB after the Master Bomber has thrown its bomb but before the bomb hits its target.
  • Master Bomber is still the most expensive T5 Ninja upgrade in BTD6, even after various price buffs throughout history.
