~ Official Description
Ray of Doom is the final upgrade of Dartling Gun on Path 1, costing $46750 on Easy, $55000 on Medium and $59400 on Hard. While the description says that it shoots a solid beam that destroys every bloon in its path, the beam actually flashes. The Ray of Doom's beam will continuously flash regardless of the cirumstances, however this is purely cosmetic - the ray's area of effect is not affected by the flashing.
The Ray of Doom has a popping power of 100, and pops bloons every frame - meaning that even Ceramic Bloons are popped in well under a second. This upgrade is probably one of the best upgrades for popping normal Bloons.

This upgrade is notoriously bad against individual M.O.A.B. class bloons, as it has a popping power of 100 but only pops 1 layer per frame. This means it effectively loses 99% of it's firepower.

The Ray of Doom used to have infinite popping power. This was changed to 100 in an update.
It would make it overpowered without the popping power limit.
A Ray of Doom can beat a B.F.B. and all bloons within it.
The Ray of Doom will pierce through anything, but if it has reached its pop limit, it will still pierce through but not pop.
The Ray of Doom only stops shooting in between Rounds. It will constantly shoot the ray during rounds, even if there are no Bloons on screen. It will also constantly shoot in Sandbox Mode.
