Targeting Priorities[]




Extra attack speed is always useful for the Ninja Monkey, with extra value in both the early-game and the late-game. The extra range provided is additionally useful for providing greater coverage for the Ninja Monkey, whether it be for hitting bloons from further or for improving Shinobi Tactics buff coverage. Because of this upgrade's joint benefits, Ninja Discipline is always the dominant crosspath for most Ninja Monkey upgrades.


  • Ninja Discipline is an extremely cost-efficient early game tower.
    • Seeking Shuriken will allow it to use its popping power fully.
    • They are usually used to lead into higher tier top path Ninjas.
  • Ninja Discipline will also increase the rate of Distraction and Counter-Espionage applying, and will also increase the attack speed of Flash Bomb and Sticky Bomb effects, so it is recommended to crosspath this path for those towers.

Version History[]

Compared to BTD5, Ninja Discipline improves the attack speed of the ninja by much more (66% compared to 20%). It can no longer have both Distraction and Seeking Shuriken at the same time, as those upgrades are mutually exclusive as crosspaths for this upgrade.

Ninja Discipline itself did not receive any balance changes since it was first released in BTD6. However, a small niche strategy involving Camo countermeasures may possibly be improved with the added Camo Prioritization for all Ninjas.

As ninja is the 'Camo Specialist' and has been since inception, it is the only tower that will unlock Camo Prioritization on the base tower. [...]
