The Ray of Doom is a persistent solid beam of bloon destruction.
~ In-game description

Ray of Doom is the final upgrade of Dartling Gun on Path 1, costing $46,750 on Easy, $55,000 on Medium, $59,400 on Hard and $66,000 on Impoppable. It allows the Dartling Gun to shoot a persistent beam that pops all bloons in its path. Unlike other upgrades, the Ray of Doom upgrade slows down the turning speed of the Dartling Gun, unless on the mobile or console versions.

The Ray of Doom has 100 pierce in Flash and infinite pierce in Mobile, popping bloons every frame (30fps); even Ceramic Bloons are popped in well under a second. This upgrade is probably one of the best upgrades for popping normal Bloons, being a tower with one of the highest pierce caps in the entire game.

In Bloons Monkey City, researching the Ray of Doom requires the Crystal Fusion Array. It costs City Cash90000 and requires Phase Crystal Terrain. It takes 120 hours to research, costs City Cash100000 for the upgrade, and requires BloonstoneIcon50.

Mechanics[]

The Ray of Doom fires a hitscan beam with 100 pierce in Flash and infinite pierce in Mobile, popping bloons every frame (30fps on Flash). It now gains the Normal damage type, letting it pop lead bloons.

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. However, with the Great Divide update, it no longer fires until a bloon exists. Also, the beam shows up in mobile no matter what, but is really thin when it should not shoot.

While by default the Ray of Doom has no targeting settings, if it is pierce capped on Flash, its beam will have Close settings for calculating what bloons to pop. In addition, the Dartling specialty tower grants it the Locked targeting option.

Strategy[]

Summary[]

Ray of Doom is super powerful at destroying regular bloons, but it tends to be somewhat weak at handling MOAB-class bloons. However, it has incredible attack speed to compensate, attacking fast enough to become a suitable solo tower. Paired with other Rays of Doom, they are actually quite efficient in terms of minimized lag versus high DPS.

Tips[]

  • There is no need to add crosspaths to a Ray of Doom, as it already possesses immense pierce and already pops any bloon type.
  • Depleted Bloontonium Darts provides no benefit to the Ray of Doom.
  • This upgrade is not the best against single MOAB-Class Bloons for its cost, as it has a max pierce of 100 (infinite on Mobile/Steam) but only pops 1 layer per frame, thus providing low single target DPS for the price.
  • When the Ray of Doom's pop limit is reached, it will prioritize bloons closer to the tower.
  • In Flash versions, Ray of Doom beams are unaffected by attack speed buffs. This is because they attack every frame (the maximum speed for any tower). Similarly, Monkey Fort and Call to Arms's pierce buffs have no effect on mobile, due to their already infinite pierce.


Differences Between BTD5 Flash and BTD5 Mobile[]

BUFF Ray of Doom has infinite popping power as opposed to 100 bloons per frame.

NERF Ray of Doom's beam has a smaller hitbox.

Trivia[]

  • Even though the description says that it shoots a persistent beam, it actually flashes, however this is purely cosmetic; the ray's area of effect is not affected by the flashing.
    • This upgrade might be a reference to the Star Wars movies, as the beam closely resembles a red lightsaber. This would also partially explain the flashing effect and when it's fired the dartling gun looks like a lightsaber handle.
  • The Ray of Doom used to have infinite pierce in the Flash version. This was changed to 100 in an update. This was because it was overpowered, being able to take out nearly anything, even mass Z.O.M.Gs, and could even be more powerful than a max temple. On mobile and steam, it still has infinite pierce, likely because the Ray of Doom is thinner on mobile.
  • This is the second most expensive upgrade in BTD5, after the Temple of the Monkey God.
  • The Ray of Doom will pierce through anything, but if it has reached its pop limit, it will still pierce through but not pop.
  • This is one of the few lasers in BTD5 that can pop Lead Bloons. The others being High Energy Beacon, Bloonsday Device, 1/3 Robo-Monkey and Meerkat Spy Pro.
  • The Death Ray Vision upgrade in Bloons Super Monkey is likely the precursor to the Ray of Doom, which also have a similar appearance and description.
