Throws heavy Kylie boomerangs that follow a straight path instead of curved.
~ BTD6 description
Kylie Boomerang is the third upgrade of Path 3 for the Boomerang Monkey in BTD6. It converts the monkey's boomerangs into Kylie boomerangs that follow a straight path instead of curved. This allows the Boomerang Monkey to attack Bloons with more accuracy and precision along straight lines. In addition to a different boomerang flight pattern, kylie boomerangs are able to re-hit the same bloons multiple times for every 0.3s of contact with the same bloon. Each kylie boomerang can pop a maximum of 18 bloons per shot (22 with Improved Rangs and 27 with Glaives).
This upgrade costs $1,100 on Easy, $1,300 on Medium, $1,405 on Hard, and $1,560 on Impoppable.
Kylie Boomerang is useful as a form of dealing high damage over straight lines. Because of the Kylie Boomerang's special rehitting mechanic, it can deal considerably high damage to normal bloons if utilized to the max. The considerably high pierce of this upgrade also makes this tower handy as moderate grouped damage.
Since Kylie boomerangs have a decent amount of pierce by itself, it is recommended to purchase Path 2 upgrades. Faster Throwing and Faster Rangs will be very helpful for optimizing the use of straight-line boomerangs and their extra damage that they have.
While the upgrade itself is decent, it is not an outstanding tower due to its main attack quickly falling off when larger rushes of bloons (especially spaced) come.
If you plan to upgrade a boomerang monkey to this upgrade, place it behind a straightaway on the track so that its pierce can be fully utilized.
Minuscule changes for Kylie Boomerang, although in Version 7.0 the +1 damage buff was carried over to its preceding Red Hot Rangs upgrade instead.
Kylie Boomerang no longer gives boomerangs +1 damage. However, boomerangs still pop 2 layers of bloon.
