How to use Armor Piercing Darts

Armor Piercing Darts makes every dart hit harder. Main darts go from 1 to 2 damage, with +2 against MOAB-class Bloons and +1 against Fortified Bloons. Airburst projectiles gain +1 MOAB and +1 Fortified damage, and their pierce goes from 2 to 5.

When to buy it

With a Berserker Brew next to it, Armor Piercing Darts can carry the mid-game: many projectiles plus strong MOAB damage. Without buffs it struggles against large groups, and it falls off after round 62.

In Sub Commander armies it is a decent piece, but 0-3-2 Ballistic Missiles or 2-0-3 Triple Guns are more cost-efficient buff targets, unless you plan to upgrade those Triple Guns anyway.

Crosspaths:

  • 2-0-4 is usually best. Advanced Intel gives it near-infinite reach, though that can break strategies that rely on stalling or precise targeting.
  • 0-1-4 or 0-2-4 add pierce and, with the middle path, let it pop Lead. These help less than the range.

Is it worth it?

Yes, as a mid-game carry with buffs and as the save point toward Sub Commander. Do not rely on it alone after round 62.
