How to use Airburst Darts
Airburst Darts changes how the darts work. Each main dart now has 1 pierce, but on impact it instantly splits into 3 airburst projectiles (4 with the Quad Burst Monkey Knowledge), each dealing 1 damage with 2 pierce. Airburst projectiles can only pop Lead or Frozen Bloons if the main dart can. With Barbed Darts, each airburst gets 3 extra pierce.
When to buy it
Airburst Darts is one of the best early-game towers on almost any map with water. It is especially strong on maps where lanes switch, like Bloody Puddles and Muddy Puddles. It only struggles to carry on maps where its shots line up poorly with the track, such as Quad.
- 2-0-2 is the standard. Advanced Intel lets it hit Bloons anywhere other towers can see, which on multi-lane maps is worth far more than extra pierce or built-in Lead popping.
- As a crosspath for 0-3-2 Ballistic Missile and above, on maps where the Sub's base range covers part of every lane.
- Optional on Bloontonium Reactor and Energizer for extra damage while unsubmerged. Not useful on Submerge and Support.
Is it worth it?
Yes. It is among the strongest early-game purchases in BTD6 if your map has water, and it scales into Triple Guns and beyond.
