All Primary Monkeys in radius get tier 1 AND 2 upgrades for free. Gains Mega Ballista attack.
~ BTD6 descrpition


Primary Expertise is the fifth-tier upgrade of the Monkey Village in Path 1 of BTD6. It allows all Tier-1 and Tier-2 upgrades for Primary Monkeys within its radius to be purchased for free, increases the pierce bonus to Primary Monkeys to +3 instead of +1, and gives the tower a powerful "Mega Ballista" attack. The attack fires a magical circular blade which strikes at any range and across barriers, and occasionally adjusts its direction mid-flight to hit more bloons, similar to Glaive Ricochet. Each blade pops 10 layers per hit and pierce through up to 100 regular bloons or 10 MOAB-class Bloons, while it deals 200 damage to Ceramics and M.O.A.B. Class Bloons. It costs $21250 on Easy, $25000 on Medium, $27000 on Hard, and $30000 on Impoppable.

DescriptionEdit

Primary Expertise is a three-towered fortress-like building with a ballista attached to the top of it.

It grants free Tier-1 and Tier-2 upgrades for all Primary Monkeys in range of the Primary Expertise. All Primary Monkeys within its radius also gain +3 pierce instead of +1 pierce. The Primary Expertise can now attack. Every 3.0s, it shoots a magical circular blade which strikes at any range and across barriers, and occasionally adjusts its direction mid-flight to hit more bloons, similar to Glaive Ricochet. Each blade pops 10 layers per hit and pierce through up to 100 regular bloons or 10 MOAB-class Bloons, while it deals 200 damage to Ceramics and M.O.A.B. Class Bloons.

Do note that while the attack detects camo, the tower itself does not and so the Advanced Intel upgrade does not detect camo bloons in the Primary Expertise's radius, unless the Primary Expertise has the Radar Scanner crosspath.

StrategiesEdit

SummaryEdit

You can use the free upgrades, best comboed with the expensive upgrades of the Bomb Shooter and Glue Gunner. However, the other buff of +3 pierce is what defines this tower, and the mega ballista attack can be useful as a mini cleanup attack.

TipsEdit

  • There is a unique synergy between this upgrade and the Inferno Ring, as it buffs the Inferno Ring's fireball attack to attack 4x as many bloons, due to granting a major pierce buff to all of Inferno Ring's attacks.

Version HistoryEdit
