Glaive Lord is the final upgrade for Path 1 of the Boomerang Thrower in BTD5. It costs $7650 on Easy, $9000 on Medium, $9720 on Hard and $10800 on Impoppable. In BTD Battles, it costs $4500. The Glaive Lord acquires two permanent glaives that rotate around the tower, shredding bloons that come into contact with the glaives. Glaive Riccochet is still used along with the rotating secondary glaives and can pop even more bloons. This upgrade also gives the tower camo detection. The glaives only rotate around the Boomerang Thrower during a round. This upgrade is perfect for compact tracks like Monkey Lane, or tracks with many curves like Park Path. This tower works very well if combined with Arctic Wind and/or Glue Hose.
