Glaive Thrower is an upgrade for the Boomerang Thrower, which allows the Boomerang Thrower to shoot Glaives instead of Boomerangs. Glaives are capable of popping up to 8 Bloons at a time in Bloons TD 3 and up to 12 Bloons at a time in Bloons TD 4 and Bloons TD 5. It is the Boomerang Thrower's third upgrade in Bloons TD 4 and second upgrade on the first path in Bloons TD 5. In Bloons TD 5, it costs $240 on Easy, $280 on Medium, $300 on Hard and $335 on Impoppable. Glaives also provide a slight increase in throwing speed.
