Turbo Charge (BTDB2)

"Turbo Charge ability: Makes this Monkey attack incredibly fast for 10 seconds."

- In-game Description

Turbo Charge is the 4th upgrade on Path 2 of the Boomerang Monkey in Bloons TD Battles 2. It is almost identical to its BTD6 counterpart, with the only clear difference being that Turbo Charge has no initial cooldown.

It costs $4,200.

Summary
Turbo Charge is a great option for dealing insane damage against tougher mid-game rounds, specifically rounds with moderate bloon density or if there are strong MOAB-class bloons. When along a location with good curves, a single use of the Turbo Charge ability can make quick work off various difficult rounds, especially when paired with the Glaives crosspath for the extra attack speed and pierce. Correct ability timing is necessary though, as it becomes weak again once the ability ends.

To fully maximize its potential, besides good placement, support it with backup defense while its ability is under cooldown, especially towers designed for countering grouped bloons. Because the Turbo Charge already comes with +1 MOAB-class damage and the ability grants +1 damage while the ability is active, even one activated Turbo Charge is capable of soloing up to BFBs while the ability is active, but it struggles heavily versus densely grouped bloons. Turbo Charge benefits well from the benefits of Primary Mentoring, most particularly the reduced ability cooldowns, and is worth adding Radar Scanner for camo detection. A really good hero to pair with is Gwendolin, as her abilities provide both effective grouped bloon damage and damage versus earlier Camo Bloon rounds.

Tips

 * Usually, 2-4-0 is better than 0-4-2 because the Glaives upgrade grants extra pierce over +1 damage and remaining at a small pierce. There are some cases where 0-4-2 is more favorable, specifically versus single-target bloons such Round 22 opponent-sent ZOMGs and Round 26 opponent-sent DDTs, and also on certain maps where the bonus range can make a bigger difference.
 * Like Bionic Boomerang, place Turbo Charge around a good curve, in order to maximize its many fast-shooting boomerangs.
 * Pair a Turbo Charge with good grouped bloon damage, such as Gwendolin (with her abilities) and 2-0-4 Recursive Cluster. In this way, Turbo Charge will have a much easier time handling with more powerful bloons, as well as giving it backup while the ability is under cooldown.
