Monkey Apprentice

The Monkey Apprentice is, arguably, the best tower (when it is a Disciple of Fire) in Bloons Tower Defense. There are those, however, who prefer to use the Super Monkey or the Spike Factory instead, but those who use the Apprentice are well respected by me. It starts off by firing little magic orbs that can pop two bloons at once, but goes up to, on Path I, firing big magic orbs, thunderbolts and tornadoes, or, on Path II, firing fireballs, magic orbs, and a stream of flame that can roast anything and everything in its way, and has a special ability that you must find out for yourself, or read this page. The upgrades for this tower are among the best of them all. Speaking of which, here they are!

Intense Magic: $300
The magic orbs are bigger and more powerful.

Thunderbolt: $1200
This makes the Apprentice, now often referred to as a Mage, fire bolts of lightning that can pop up to twenty-five bloons!

Summon Whirlwind: $2000
This makes the Disciple of Air occasionally shoot a whirlwind that can blow twenty-five bloons at once back to the entrance.

Tempest Tornado: $8000
The Tempest blows more bloons, and blows them further.

Fireball: $300
This adds a powerful, exploding fireball attack to the Apprentice's arsenal.

Monkey Sense: $300
This enables the Apprentice to spot Camo Bloons.

Dragon's Breath: $4200
Now it's a Disciple of Fire. The Disciple of Fire shoots endless flames, roasting any bloon with ease.

Summon Phoenix: $5000
Summon Phoenix Attack: Creates a firebird that flies around, wreaking bloon havoc for 20 seconds.
