Energizer is the 5th upgrade of the Monkey Sub in Bloons TD Battles 2. It is very similar to its BTD6 counterpart, with differences. It gives +75% more XP to all nearby heroes, and does a lot more Ceramic damage with radiation. Radiation deals 5 damage and +10 to Ceramics, and does so every 0.4s (0.3s with 5-0-1, 0.2s with 5-0-2) and affecting 1000 bloons per pulse. Energizer also discounts the cash required to level up heroes manually by the inverse ratio of the XP multiplier, specifically 57% of the original cost. Decamo pulse is 1000 pierce, increased to 1200 and 1500 with the Path 2 crosspaths.

It costs $32,000, and is unlocked with the other tier 5 Monkey Sub upgrades for 1500.

Strategy[]

Summary[]

Energizer reduces cooldowns of all abilities in the game, a game mechanic that is unique to this tower. Because it can affect all abilities, it is especially impactful for income abilities, especially Jungle's Bounty, Supply Drop, and Support Chinook.

Tips[]

Crosspath with Path 3 for the speed benefit since path 2's pierce benefit is insignificant in comparison.
It may be helpful to have this Energizer added in combination with at least 10 of any ability alt eco towers.
For a less passive set-up, it may be in the player's interests to use an Energizer for abilities like The Anti-Bloon's, certain Hero abilities, Pop-and-Awe, or Tsar Bomba.

Trivia[]

Towers placed on Ice platforms will be considered to be water towers as well, granting them 50% ability cooldowns instead of 20%. This can be used to have 100% uptime on various abilities such as Grand Sabatour.
