Reduces ability cooldowns everywhere by 20%. While in radius, heroes earn XP 50% faster and water Monkey ability cooldowns are halved.
~ Upgrade description in BTD6.

The Energizer is the final upgrade of Path 1 for the Monkey Sub in BTD6. It makes Heroes earn XP 50% faster, reduces cooldowns of all water Monkeys in the radius by 50% (doesn't stack with Bloontonium Reactor), as well as reducing ability cooldowns for ALL other towers on screen by 20%. It also increases the pierce of the Bloontonium Reactor attack from 70 to 1000 and the damage from 1 to 3.

It costs $27,200 on Easy, $32,000 on Medium, $34,560 on Hard, and $38,400 on Impoppable.

TipsEdit

  • Just as with its previous upgrade, crosspath with Path 3 to increase its damage output. However, crosspathing 5-0-0 does not really hurt since the tower benefits more from a supporting role in the late game.
    • It is notable that since 18.0, Admiral Brickell's Naval Tactics and Sub Commander can buff Energizer's DPS and this may combo better with the bottom crosspath.
  • This upgrade is very useful when defenses are ability-heavy, particularly with income-related abilities such as Jungle's Bounty, Supply Drop, and Support Chinook's Crate Drop Ability.
  • It is worth noting that the Energizer also affects the life-loss passive abilities of Bomb Blitz, Elite Defender and Legend of the Night.
  • The water heroes Pat Fusty and Admiral Brickell both synergise well with Energizer, as they benefit from both the increased Hero XP and the reduced cooldown on their abilities, especially since their abilities are extremely powerful buffs. 
    • Admiral Brickell is arguably the best hero to pair with the Energizer, as her abilities are highly effective for water-based terrain. Similar to Pat, her buff has a much higher uptime. 
      • Additionally, with the "Ability Master" Monkey Knowledge, it is possible for Brickell in range of an Energizer to provide near-permanent buffs with her Naval Tactics ability.

BugsEdit

  • The visual indicator in the buffs section above a tower inconsistently displays the submerged and unsubmerged buffs. Additionally, sometimes, the bug shows both sprites indicating a submerged and unsubmerged buff. This bug has been known since 12.0 and occurs as of 14.0.

TriviaEdit

  • The description used to be "Hero earns XP 50% faster while in Energizer's radius. Cooldowns for abilities of water Monkeys in the radius are halved." but has changed due to the changes in Version 2.0.0.
  • The XP boost only works for Heroes in the radius, as verified by Challenge Editor.
  • When crosspathed with upgrades on the bottom path, two guns appear on the bottom of the Energizer.
  • Since Pat Fusty can be placed on water or land, he can benefit from either 50% ability cooldown or 20% depending on where he is placed.
  • Energizer was used to complete the first ever 2 towers C.H.I.M.P.S. with The Anti-Bloon. It no longer works now, but recently in 17.0 it was used with Dark Champion in 2 towers C.H.I.M.P.S. because of the latter's buff in the update.
  • The Version 2.0 buff was likely inspired by the High Energy Beacon from BTD5, which grants 20% decreased ability cooldowns for nearby towers, although the Energizer's buff in Version 2.0 affects global range.
