Energizer is the Monkey Sub's path 1 tier 5 upgrade in Bloons TD 6. This upgrade allows Monkey Sub to grant a buff to all towers on screen which reduces their ability cooldowns by 20%. For water-based towers within its range, this buff reduces ability cooldowns by 40% instead of 20%. Heroes within its range gain +50% XP from the ends of rounds and sacrifices (not from purchasing levels).

This upgrade also improves Monkey Sub's attack. The pierce of both its decamo and damage auras are increased to 1000, and its damage aura's damage is increased from 1 to 5 with additional +5 Ceramic damage. This upgrade increases the damage of Monkey Sub's darts from 2 to 5 while not submerged, including Airburst Darts with the 5-0-2 crosspath.

Strategy

This section was last updated for: version 51.0

Energizer is a multi-purpose tower that excels in certain scenarios. It is the most potent in Freeplay and against Boss Bloons, where its cooldown reduction is essential for towers like Ultraboost and Homeland Defense. In the farming process of these game modes, Energizer is also crucial due to it reducing cooldowns for money generators as well. However, when using Adora in Freeplay, submerging Nautic Siege Core is recommended, making Energizer redundant for the final setup in that scenario.

In other game modes, Energizer's main use is allowing slower-leveling Heroes reach higher levels before Round 100. The Heroes that benefit the most are Admiral Brickell, Psi, Captain Churchill, and Sauda. In particular, Admiral Brickell's powerful Naval Tactics and Mega Mines abilities have their cooldowns nearly halved, making her synergize really well with Energizer. The ability cooldown reduction to towers is a good bonus, but it is not sufficient on its own to justify using Energizer outside of Freeplay and Boss Bloon battles. 5-0-1 is the preferred crosspath, as the extra pierce and Lead damage popping power and bonus from 5-2-0, most of the time, are not favorable and 5-0-1's attack speed allows for better cleanup of Super Ceramic Bloons.

•  Pulse: rate reduced ― 0.3s → 0.19125s

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 31.0

“

Energizer upgrade offers nothing extra to the reactor sub aside from niche utility buffs, so we have increased the lategame cleanup potential by a large amount to help deal with Super Ceramics. — Update notes

”

•  Pulse: Damage increased ― 3 → 5
•  Pulse: Now gains bonus Ceramic damage ― +0 → +5

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 → 1000

5-1-0

•  Camo Pulse: Pierce reduced ― infinite → 1020

5-2-0

Version 34.2

•  Ability cooldown reduction for land towers decreased ― 40% → 20% (bug fix)
•  Ability cooldown reduction for water towers decreased ― 70% → 50% (bug fix)

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

”

•  Submerge targeting is now mapped to Monkey Special 1

5-1-0

•  Decamo pulse: Pierce increased ― 120 → 150
•  Damage pulse: Pierce increased ― 70 → 100

5-2-0

•  Heat-tipped Darts no longer increases decamo pulse pierce by 30
  •  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)

5-0-1

•  Damage pulse and decamo pulse: Attack cooldown bonus increased ― -15% → -30%
  •  Overall attack cooldown reduced ― 0.255s → 0.21s

5-0-2

•  Airburst Darts no longer reduces the attack cooldown of the damage pulse
  •  Overall attack cooldown increased ― 0.19125s → 0.21s (due to changes to the previous tier)

Version 41.1

•  Submerge toggle now has a 1-second cooldown

Version 42.0

“

As currently nothing else ever happens with the main attack beyond T2 on the top path we want to give Energizer a little more power here to promote reason to un-submerge, although knowing how well this attack scales in terms of buffability we’re starting off with a careful amount to not take this too far. — Update notes

”

•  Main dart: damage increased ― 1 → 5
•  Retry Last Round no longer removes the submerge toggle (bug fix)

5-0-2

•  Airburst dart: damage increased ― 1 → 5

Version 43.0

“

The bonus to Lead on Reactor currently doesn't apply to T5, so this bonus is being carried up and improved along with a small price reduction to Energizer as strategies using it have fallen somewhat in viability. — Update notes

”

•  Upgrade cost reduced ― $32,000 → $31,000

5-2-0

•  Radioactive pulse: Gains bonus Lead damage ― +0 → +5

Version 44.0

• Buff icon now appears on X-4-X Beast Handlers

Version 45.0

We’re improving Reactor’s attack cooldown to improve general consistency. — Update notes

”

5-0-1, 5-0-2

“

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 50.0

•  Local water buff: No longer reduces Ice Monkey cooldowns by 50% unless the target is placed on water (bug fix)

Version 50.2

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

Version 51.0

“

Energizer’s cooldown reduction for nearby water towers has always felt excessive, so we’re dialing it back to 40%, still strong just not quite double uptime strong. — Update notes

”

•  Ability cooldown reduction bonus to nearby water towers decreased ― −50% → −40%
• Description changed ― Reduces ability cooldowns everywhere by 20%. While in radius, Heroes earn XP 50% faster and water Monkeys ability cooldowns are halved. → Reduces ability cooldowns everywhere by 20% and by 40% for Water based Monkeys. While in radius, Heroes earn XP 50% faster.
