Multiple Object Advanced Riccochet greatly enhances the already extrordinary powers of the Glaive Riccochet Monkey.
~ BTD6 description
M.O.A.R. Glaives is the fourth upgrade of Path 1 for the Boomerang Monkey in Bloons TD 6. It enhances the ricochet ability of the Boomerang Thrower's Glaives by doubling its attack speed, jump distance between bloons, and pierce (to 100). It costs $2550 in Easy, $3000 in Medium, $3,240 in Hard, and $3,600 in Impoppable.
MOAR Glaives is an extremely powerful tower against bloons. It is best paired with an anti-MOAB attacker midgame, namely Arcane Spike. Although it begins falling out of favour late game, it can still do fair chunks of damage to hyperclumped superceramics.
As of the Version 7.0 update, MOAR Glaives is best paired up with Red Hot Rangs. Despite shooting around 55% faster than when upgraded to Faster Rangs instead (1.25*1.25 attack speed bonus), the +1 damage essentially doubles the damage of MOAR Glaives.
In the same idea, a 4-0-2 Boomerang can beat round 63 all by itself on many maps.
