BTD6

Sub's darts can pop an additional 3 bloons each.
~ In-game description

Barbed Darts is the first upgrade of Path 2 for the Monkey Sub in Bloons TD 6. It increases pierce of each main dart from 2 to 5. For Airburst Darts, darts still split on impact but each individual airburst dart receives +3 pierce. For Bloontonium Reactors, pierce of the damaging radiation zone increases from 50 to 70, and gives +20 pierce for the decamo pulses of Submerge and Support and above.

This upgrade costs $380 on Easy, $450 on Medium, $485 on Hard, and $540 on Impoppable.

Description[]

Appearance[]

Barbed Darts adds a red arrowhead on the top of the submarine's gun holder. For Submerge Subs and Reactors, the telescopes' lenses become red instead of green.

Mechanics[]

All darts including those burst from Airburst Darts gain +3 pierce. Base darts have 5 pierce. Armor Piercing Darts instead increases pierce from 5 to 8, while Sub Commander pierce increases from 9 to 12 because it receives its own buff. Reactors and Energizers gain +20 pierce.

Targeting Priorities[]

Barbed Darts targets bloons using the standard targeting priorities. It shoots straight movement projectiles that can moderately seek at bloons.

  • First: Targets the first bloon visible within its range.
  • Last: Targets the last bloon visible within its range.
  • Close: Targets the closest bloon visible within its range.
  • Strong: Targets the strongest bloon visible within its range.

Adding Advanced Intel does not add Camo Prioritization, despite being a potential option for camo detection.

Strategy[]

Summary[]

Barbed Darts will produce more pierce potential overall compared to adding Twin Guns, but for the same cost it doesn't have as much early-game value in comparison. This is because a majority of the issues in early-game come from the faster bloons rather than grouped bloons. However, this upgrade can come in handy when extra dart pierce is necessary.

Tips[]

  • This upgrade increases pierce, allowing for better popping power. It is usually just a stepping stone to higher upgrades.
  • There are some uses out of the 0-1-2 for advancing against grouped rounds. However, in general cases, grouped bloons aren't always a problem and 2-0-2 is better for general cases.

Version History[]

Mostly implemented crosspath interactions with non-dart attacks.

18.0
  • Buff Heat-Tipped Darts crosspath now gives submerged Bloontonium Reactors with extra pierce.
23.0
  • Nerf Pierce bonus for submerged Bloontonium Reactors and Energizers decreased (+20% → additive +30; 84 → 70 for Reactors, and 1200 → 1030 for Energizers)
    • Energizer pierce reduction is undocumented in Ninja Kiwi's Version 23.0 patch notes.
32.0
Similar types of camo reveal like Shimmer/Signal Flare/Embrittlement are all pierce limited, but the Submerge sub has practically infinite pierce while also being extremely cheap with a very fast rate and a T4 that is far better at camo removal than those other towers can reach. Giving this upgrade a more reasonable pierce value brings these more in line and allows for the pierce crosspath to have some potential meaning.
~ Ninja Kiwi, referring to Upper Path 1 Sub
  • Nerf Barbed Darts now adds a limited pierce bonus for Upper Path 1 Sub decamo pulses instead of leaving them at infinite pierce.
