Throws 3 darts at a time instead of 1.
~ BTD6 Description
Triple Shot is the third upgrade of Path 2 for the Dart Monkey. With this upgrade, Dart Monkeys will shoot three darts at a time instead of one. However, the darts pierce is not upgraded and remains at 2 (with up to 4 extra pierce (+1 from 1/x/x and an additional +2 from 2/x/x, as well as +1 from Extra Dart Pops).
It costs $340 on Easy, $400 on Medium, $430 on Hard and $480 on Impoppable.
Triple Shot is a decent early-game option for all-round damage to standard bloons, specifically against spaced Yellows and Pinks, as well as groups of weaker bloons. It is more expensive compared to its BTD5 counterpart and has overall less pierce without Path 1 crosspathing, but it still serves a very similar but useful early-game role. Triple Shot is more superior than its sisterly upgrade Crossbow in its specialty, but Crossbow still has the edge versus stronger early-game bloons later on in the game, which means it is often outclassed in most cases.
If you do not mind not having an optimised strategy or are playing on an easier map/difficulty, Triple Darts is still extremely usable.
If the "Bonus Monkey!" and "More Cash" Monkey Knowledge Points are unlocked, then one 0-3-0 Dart Monkey can be afforded at the start of the game even in Impoppable.
Triple Shot synergizes better with Benjamin when it comes to penny-pinching early-game income. This is because the Biohack ability's damage buff is more significant on the Triple Shot's multiple darts than the Crossbow's single arrows.
