Glaive Riccochet

 is the 3rd upgrade of path 1 for the Boomerang Thrower in Bloons Tower Defense 5. It costs $1275 on Easy, $1500 on Medium and $1620 on Hard. It allows the Boomerang Thrower to throw a glaive that bounces from bloon to bloon as long as there is one close by. This means that the glaive will continue and pop up to 100 (101 if the first bloon popped is a Red Bloon; 40 in Bloons Monkey City) bloons along the path similarly to a homing Juggernaut. However, this does not mean that the glaive will continuously ricochet between two bloons as the glaive will not attack bloons it has already popped.

The tower turns purple and gets a blue X on his back, just like the X on the Glaive thrower. This upgrade is good when there are lots of bloons in a crowd. 

Trivia

 * This upgrade previously costed $935 on Easy, $1100 on Medium and $1190 on Hard.
 * Before an update, it could pop 10000 bloons at once.
 * In Bloons Monkey City, it can now only pop 40 bloons, however the price has been lowered to $1400.
 * The first bloon hit by the glaive will get two of its layers popped.
 * In the iOS version, if the tower is not upgraded with Red Hot 'Rangs, it will make no sound when it tries to hit Lead Bloons. This also occurs with Glaive Lord.
 * When combined with a Bloonchipper it can decimate all bloons inside.
 * Although it cannot be easily seen, the glaives from Glaive Riccochet can bounce off M.O.A.B-Class Bloons; it is easier to see when the blimps are first damaged by the glaive if the Premium Upgrade Big Bloon Sabotage is active.
