Bloonjitsu (BTD6)

"Throws 5 shurikens at once!"

- In-game description

Bloonjitsu is the 4th upgrade on Path 1 for the Ninja Monkey in Bloons TD 6. This upgrade allows the Ninja to throw 5 shurikens at once (6 with the Deadly Tranquility MK) instead of 2, in a spray with narrow angular distance per shuriken. Each shuriken pops 4 bloons each, and shuriken attacks volleys are shot every 0.42s.

However, unlike BTD5, it is not possible to crosspath a Bloonjitsu with both Distraction and Seeking Shuriken.

It costs $2,335 on Easy, $2,750 on Medium, $2,970 on Hard, and $3,300 on Impoppable.

Summary
Just like its BTD5 counterpart, Bloonjitsu is decent as an early mid-game option on its own, more specifically with the Seeking Shuriken crosspath. Even though both Distraction and Seeking Shuriken are mutually exclusive for a Bloonjitsu, it is a superior early mid-game carrier with Berserker Brew or Stronger Stimulant, as this increases the damage of all its shurikens by +1 plus extra pierce for basically full uptime. 4-0-1+ Bloonjitsu + Stronger Stimulant is a popular combo among many CHIMPS games because of how powerful this combo is.

Tips

 * Generally, the Path 3 upgrades, particularly Seeking Shuriken, are better as it massively helps the Bloonjitsu to make use of its fairly large pierce, relatively high attack speed, and relatively high number of projectiles per attack.
 * This becomes more relevant when the Ninja is Alchemist buffed as its max pierce effectively becomes a whopping 35 (across 5 projectiles), and each shuriken will deal effectively double damage!
 * With Seeking Shurikens, the Bloonjitsu can also have Caltrops for slightly more overall popping power via regular caltrop attacks onto nearby track. Caltrops placed on the map even keep their Alchemist buffs even if the brew wears off after placement.
 * Arguably, Distraction is more useful late game because Seeking Shuriken falls off from being reliable DPS later on, although Shinobi Tactics spam often deals with that aspect just as effectively as one Bloonjitsu with Path 2 upgrades.
 * Bloonjitsu Ninjas are among the best candidates for Berserker Brew and Stronger Stimulant, even after the Version 6.0 Alchemist nerf. This is because they do not shoot so fast as to expire potions early but at the same time shoot many projectiles at once with good overall pierce and damage. As a result, take caution when upgrading a Bloonjitsu further to Grandmaster Ninja and/or buff it with many Shinobi Tactics Ninjas, as these two methods will cause the ninja to use up the buff quicker, though either are not bad options with Alchemist brews even with fast expiry.
 * In fact, a 4-0-2 Ninja + 4-x-x Stronger Stimulant can solo up to Rounds 52 with almost full ease on almost all maps with decent range.
 * One 4-0-2 Ninja costs $5835 on Hard Difficulty.

Trivia

 * Unlike BTD5, the Bloonjitsu Ninja Monkey wears a rice hat. Its previous upgrade is the one to wear a white hood instead.
