Damages many more Bloons with a deadly ring of flame instead of tacks.
~ In-game description

Ring of Fire is the fourth upgrade of Path 1 for the Tack Shooter in Bloons TD 6. It exchanges the hot tacks from Hot Shots with deadly flame rings. These rings shoot at a +33% faster rate (every 0.47s) and deal 3 damage each (+1 per Path 3 crosspath) to up to 60 bloons per fire blast (+10 per Path 2 crosspath). Although much weaker against MOAB-class bloons compared to the previous upgrade, it is extremely powerful versus regular grouped bloons prior to the rise of Super Ceramics. It cannot pop Purple Bloons, a weakness that only itself and Inferno Ring possesses, at least for the Tack Shooter.

This upgrade costs $2,975 on Easy, $3,500 on Medium, $3,780 on Hard, and $4,200 on Impoppable.



This upgrade increases the diameter of the base, decreases its height, and is now black. The overall tower's color changes from a gold-yellow to a blood-orange, while its eight black ported barrels glow white hot from the heat. The extruded features that hold the barrels are colored yellow at the end. An additional orange flange is added between the black base and tower. The rounded top is removed and replaced with an indefintely blazing fire, revealing a hollow interior.

Path 2 crosspathing increases the Tack Shooter's height and adds claw-like protrusions to its base.

Path 3 crosspathing adds extra turrets on the side, 2 with More Tacks, 4 with Even More Tacks.


Ring of Fire exchanges the Orbital Spray for a Zone attack that affects the entirety of its range; it also deals +1 damage (for 3) with 60 pierce, and 33% faster attack speed (0.47 second attack cooldown)

Crosspathing is significantly different compared to before; now both path 2 upgrades grant +10 pierce on top of their range buffs and both path 3 upgrades grant +1 damage instead of +2 projectile count.

Targeting Priorities[]

Ring of Fire shoots flame rings in a zone-like style. Technically, the Tack Shooter is locked on the Close targeting priority. However, for simplicity reasons, Ring of Fire has no targeting priorities.

Sacrificing its high MOAB-class damage for much stronger grouped damage, the Ring of Fire is an effective method for countering grouped bloons. It is highly effective against mid-game grouped bloons, but it falls off greatly in late-game, where a majority of regular bloons are Super Ceramics.


  • The better crosspath for Ring of Fire depends on the map. Use the 4-0-2 crosspath for wiping out stronger groups of bloons within a close range, but use the 4-2-0 crosspath for greater coverage and popping of weaker groups of bloons. Because Ring of Fire has poor base range, in most situations 4-2-0 is usually the better option.
  • Like all Tack Shooters, place a Ring of Fire along a corner or bend to optimize its attacks.
  • Ring of Fire is rather poor against Super Ceramics, but it is not at all completely useless against them. Paired with Ice Monkeys with Re-Freeze and Enhanced Freeze, Ring of Fire can deal with larger groups of Super Ceramics pretty effectively, just not very efficiently.
  • When used for CHIMPS Mode, only one Ring of Fire should be bought if wanting mid-game popping power, as Rings of Fire tend to fall out in late-game due to Super Ceramics. If possible, the Ring of Fire can be upgraded to Inferno Ring to scale better versus Super Ceramics and MOAB-class.

Version History[]

Buffed to deal more damage and interact with crosspathing more fairly. The current iteration of crosspathing benefits is that Path 2 hybridizes range and pierce while Path 3 adds more damage.

  • Buff Ring of Fire deals more damage (2 → 3)
Inferno Ring has felt very outclassed for a long time, and more recently the tack shooter was reworked to give pierce on x2x which made the old 402 pierce crosspath not make as much sense anymore. We wanted to start work on both these issues together by reworking how Ring of Fire and Inferno Ring interact with crosspaths
~ Ninja Kiwi
  • Buff 410 and 420 Ring of Fire now adds +10 pierce with each Path 2 upgrade
  • Buff 402 Ring of Fire now adds +1 damage (3 → 4)
  • Nerf 401 and 402 Ring of Fire now no longer grants bonus pierce
The Ring of Fire & Inferno Ring upgrades recently received a crosspath functional rework, as we're happy with the x2x range/pierce combo now this small follow-up is just to bring a bit more impact to the short-range 402 variant.
~ Ninja Kiwi
  • Buff All Path 3 upgrades now add +1 damage to the flame ring per upgrade
Ring of Fire doesn't perform well for the price as a low-range AoE tower with no single target advantage. Since we value the original design intent as low range AoE, we've lowered the price to remain a viable choice.
~ Ninja Kiwi
  • Buff Ring of Fire cost decreased ($4500 → $3500)
  • Change Description changed from "Shoots a deadly ring of flame instead of tacks." to "Damages many more Bloons with a deadly ring of flame instead of tacks."
Ring of Fire doesn’t keep up well enough for where it is placed, so the attack speed increase from this upgrade has been bumped up from 15% to 25%. [...]
~ Ninja Kiwi
  • Buff Ring of Fire attack cooldown reduced from 0.5355s → 0.4725s. Buff does not carry over to Inferno Ring.

  • Unlike BTD5, the Tack Sprayer upgrade is now on a separate path, Path 3, which mostly centres around gaining extra projectiles.
  • With the new price as of Version 22.0, the cost of the Ring of Fire is now the same cost as it is in Bloons Monkey City Mobile, which apparently costs $3,500 to compensate a possible projectile duplication bug from Monkey Fort.
  • The Tier 3 upgrades Blade Shooter and Tack Sprayer were precursors to Ring of Fire in earlier generations of the Bloons TD series, before BTD5 and during the BTD5 generation, respectively.
  • Ring of Fire is the only Primary Monkey upgrade below Tier 5 that uses the fire damage type. Although Red Hot Rangs uses fire in its boomerangs, it deals normal damage instead.
