Bloontonium Reactor is the Monkey Sub's path 1 tier 4 upgrade in Bloons TD 6. It improves the Monkey Sub's decamo pulses while submerged, now dealing 1 damage to Bloons in addition to removing the Camo property. The damage pulse has a pierce of 50 (compared to the decamo pulse's pierce of 100) and cannot damage Lead Bloons. This upgrade also reduces the pulse's attack cooldown by ~79% (0.28 seconds, or 0.196 seconds with 4-0-1), effectively increasing its attack speed by ~4.82x. Bloons hit by the damaging pulse are irradiated for the same duration as its attack cooldown, which prevents Bloontonium Reactors and Energizers from stacking their damage. While submerged, towers placed on water within its range are granted a buff that reduces their Activated Ability cooldowns by 15%.

This upgrade increases the damage of Monkey Sub's darts from 1 to 2 when not submerged. This includes Airburst Darts, if crosspathed as 4-0-2.

Strategy

This section was last updated for: version 53.2

Bloontonium Reactor is a good multi-purpose tower for the early-mid game, cleaning up Bloons below Ceramics well and performing reliable de-camo. Its damage aspect excels the most in Race Events, thanks to its high pierce. There, it is recommended to purchase a 0-2-0 into 3-2-0 Berserker Brew to buff Submerge and Support, sell Berserker Brew, upgrade the Submerge and Support into a 4-1-0 Bloontonium Reactor, and pair it with Ice Shards. 4-2-0's innate lead-popping isn't necessary unless lead-popping is very scarce.

Outside of Race Events, Bloontonium Reactor remains useful into the late-game thanks to its near-instant de-camo of DDTs and cooldown reduction for water towers, most notably for Admiral Brickell and First Strike Capability, the latter on maps that require Bloontonium Reactor for two ability usages against Round 100. In both Race Events and general gameplay, it is best placed so that it has maximum coverage of the track and has the greatest track length available for cleanup.

4-0-1 is the optimal crosspath outside of Race Events, for stronger cleanup capabilities, with 4-1-0 only needed when the extra pierce is better. 4-0-2 does have stronger Airbursts, but redundant if not planning to use it for early MOABs.

Version 15.0

• "Optimized art for all submerged versions"

Version 17.0

• "Bloontonium Reactor buff icon issues resolved" (bug fix)

Version 18.0

•  Range increased ― 50 → 52

4-1-0

•  Damage Pulse: pierce increased by 20% ― 70 → 84

4-2-0

•  Damage Pulse: now gains +1 Lead bonus

4-0-1

•  Pulse: rate reduced ― 0.3s → 0.255s

4-0-2

•  Pulse: rate reduced ― 0.3s → 0.19125s

Version 23.0

“

As Bloontonium Reactor rarely uses up enough pierce that the pierce crosspath would ever matter, a large chunk of this has been moved into the middle crosspath. — Update notes

”

•  Damage pulse: base pierce reduced ― 70 → 50
  • Note: Does not affect Energizer (1000)

4-1-0

•  Damage pulse: base pierce reduced ― 84 → 70
  • Note: Pierce bonus increased from +14 to +20

4-2-0

•  Damage pulse: base pierce reduced ― 84 → 100
  • Note: Pierce bonus increased from +14 to +50

Version 29.0

“

The logic on a Lead crosspath not being required to give Lead popping to an attack based on something weak against Lead has never sat right, so we’re finally sorting that out and making sub a little angrier. — Update notes

”

•  Damage pulse: Damage type changed ― Normal → Shatter
  • Note: 4-2-0 and 5-2-0 damage type remains Normal

Version 32.0

“

Similar types of camo reveal like Shimmer/Signal Flare/Embrittlement are all pierce limited, but the Submerge sub has practically infinite pierce while also being extremely cheap with a very fast rate and a T4 that is far better at camo removal than those other towers can reach. Giving this upgrade a more reasonable pierce value brings these more in line and allows for the pierce crosspath to have some potential meaning. — Update notes

”

•  Camo Pulse: Pierce reduced ― infinite → 100

4-1-0

•  Camo Pulse: Pierce reduced ― infinite → 120

4-2-0

•  Camo Pulse: Pierce reduced ― infinite → 150

Version 41.0

“

We have come back a number of times to add, fix & balance sub crosspathing, over years of learning though it currently feels messy and we’d like simplification. Heat-Tipped Darts doesn’t increase base sub pierce, so it feels silly to require it for maximum pierce on Submerged subs. Likewise Airburst shouldn’t be required to maximize the rate of submerged subs, instead we’d rather give people an easier way to work with the Airburst attack if they desire to upgrade to it so ‘Submerge’ is moving to a new Tower Special rather than target priority. — Update notes

”

•  Upgrade cost reduced ― $2,500 → $2,300
  •  Overall cost is unchanged (due to cost changes for previous tiers)
•  Submerge targeting is now mapped to Monkey Special 1

  •  Overall pierce is unchanged (due to changes to the previous tier)
•  Heat-tipped Darts no longer increases damage pulse pierce by 30
  •  Overall pierce is unchanged (due to changes to the previous tier)

4-0-1

  •  Overall attack cooldown reduced ― 0.255s → 0.21s

4-0-2

  •  Overall attack cooldown increased ― 0.19125s → 0.21s (due to changes to the previous tier)

Version 41.1

4-0-1, 4-0-2

Version 49.0

“

Some feedback was convinced this would be enough to solve many concerns, so ok 👍 — Update notes

”

•  Submerge toggle: Cooldown reduced ― 1s → 0.5s

Version 50.2

•  No longer should have less range when targeting MOAB-Class Bloons (bug fix)

Version 53.0

“

Monkey Sub kept leaving bags of poop on our doorstep and will be gaining improved reliability for its de-camo pulse, with Reactor already doing very good at this and buildup growing more reliable from the change it gets a tiny price raise. — Update notes
