Bloons Wiki
Creates a blast of thorns for each attack. Upgrades can call forth powers of the Jungle, Storm, or Wrath.
~ In-game Description

The Druid is a Magic Class tower in the Bloons TD series. It first appears in Bloons TD 6 along with the Alchemist. They can be chosen and unlocked in-game between ranks 14-18.

It costs $360 on Easy, $425 on Medium, $460 on Hard and $510 on Impoppable.


The Druid is a white-tan monkey that throws several small wooden thorns, which can destroy multiple bloons and/or layers, depending on its distance, similar to a shotgun. This tower's thorns, however, are ineffective against most special bloons attributes and requires upgrades to get much farther than that. Unfortunately, a majority of their early upgrades cannot detect camo attributes on its own and must be assisted by towers such as the Monkey Village and its camo detection upgrades. The first path for the Druid is similar to the first path of the Monkey Apprentice in BTD5. It is more powerful in groups with both its wrath and jungle forms being much more effective with other monkeys or Druids.


Path 1 focuses on dealing damage to grouped bloons and knockback. Hard Thorns adds 1 pierce to each thorn, and the thorns can now pop frozen bloons. Heart of Thunder is similar to the Wizard Monkey's Lightning Bolt from BTD5, dealing damage to multiple bloons. (Up to 30 for each bolt) Druid of the Storm can blow back up to 30 bloons, pushing them towards the entrance, similar to Downdraft. Ball Lightning summons large balls of electricity that deal damage to multiple bloons. Finally, Superstorm summons massive tornadoes that can blow back MOAB-Class bloons, at the cost of more pierce. Superstorm also increases damage for most of the Druid's attacks.

Path 2 focuses on dealing damage from far away. Starting with increased projectile count with Thorn Swarm and regrow stripping with Heart of Oak. The Druid's Tier 3 upgrade is Druid Of The Jungle, which insta kills the strongest non MOAB class bloon on-screen. Then the Tier 4 upgrade is Jungle’s Bounty, which generates 200 cash per ability use, with more money being able to be added by nearby Banana Farms, and finally, the Tier 5 upgrade is Spirit Of The Forest, which lays damaging vines across the track.

Path 3 focuses on dealing more damage conditionally. Druidic Reach increases the Druid's range by a decent amount. Heart of Vengeance increases attack speed and damage for each life lost, and Druid of Wrath increases attack speed further, as long as the Druid is attacking bloons. Poplust buffs nearby Druids' attack speed and pierce, stacking up to 5 times on any single Druid. Finally, Avatar of Wrath does 4 damage by default, plus 1 more damage for each 3,000 RBE that round, capping at 90,000 RBE, or an extra 30 damage.

Monkey Knowledge[]

This section displays Monkey Knowledge that has effects on Druid and its changes when compared to one by default:

Version History[]

  • Release

Balance Changes[]

  • Buff x-4-x Jungle's Bounty now produces much more cash with a bigger range.
  • Buff x-5-x Spirit of the Forest +1 damage to all attacks.
  • Buff x-5-x Spirit of the Forest track vines now deal +4 damage to ceramics & MOABs.
  • Buff x-5-x Spirit of the Forest's T3 Jungle Vine attack targets bloons about 20% faster.
  • Buff x-x-2 Heart of Vengeance 10% of the maximum possible 100% attack rate boost from lives lost is now permanently applied upon upgrading. This 10% bonus will always apply to any druid with this upgrade, even in Impoppable & CHIMPS modes.
  • Buff 5-x-x Superstorm, Super Storm damage increased from 5 to 12.
  • Buff 5-x-x Superstorm, Ball Lightning damage increased from 2 to 5.
  • Buff 5-x-x Superstorm, Lightning damage increased from 1 to 3.
  • Buff x-5-x Spirit of the Forest no longer generates lives per round, but will generate lives on every ability use instead. This is to better synergize with the bottom path by not automatically reducing the bonus from Heart Of Vengeance every round.
  • Buff x-5-x Spirit of the Forest ceramic damage bonus increased from 4 to 8.
  • Buff x-4-x Jungle's Bounty base range increased from 35 to 55.
  • Nerf x-4-x Jungle's Bounty ability range reduced to match base tower range.
  • Nerf x-4-x Jungle's Bounty cash gained per farm reduced from $150 to $100.
  • Buff x-2-x Heart of Oak now allows the Lightning, Whirlwind & Ball Lightning attacks to remove the regrow property from any Bloons they hit.
We've wanted to work on this upgrade for a while but first had to deal with an issue causing it to perform far differently to intended. Unfortunately while we expected improvement from this fix, it ended up being an overall nerf. We have cut the price by a large amount to counter this and will revisit the upgrade again after this settles.
~ Ninja Kiwi
  • Buff x-5-x Druid Spirit of the Forest price reduced from 50,000 → 35,000.
Superstorm has been adjusted with a new feature to grant it a method of dealing continuous damage to the targets that it blows backwards. We know many of you will feel this needs much more work but please be patient as we will come back to it.
~ Ninja Kiwi
  • Buff Superstorm's Storm now spawns Ball Lightnings in a 180 degree arc in front of it every second until the storm expires.
The most recent buff to Superstorm was great fun, but when spending pierce so quickly we wouldn't see many extra Ball Lightnings. Since many find Superstorm lacking in pierce overall, the 'extra' pierce consumptions for hitting larger targets have been reduced to make it more effective and more lightningey.
~ Ninja Kiwi
  • Buff Ball Lighting price decreased ($6,000 → $5,500)
  • Buff Superstorm's superstorm pierce consumptions is now decreased for all MOAB-class bloons:
    • MOAB: 20 → 5
    • BFB: 50 → 20
    • ZOMG: 200 → 50
    • DDT: 50 → 10
Druid's top path Storm & Ball Lightning upgrades needed a value boost versus other options versus other paths of other tower choices, so these have been given a small price buff for now.
~ Ninja Kiwi
  • Buff Druid of the Storm price reduced from $2,000 → $1,850.
  • Buff Ball Lightning price reduced from $5,500 → $5,100.
As an underused crosspath on this tower, Druid’s Hard Thorns will now allow them to counter all of its weaknesses instead of just frozen targets. Druid of the Storm has been reworked to more consistently blow targets back due to being stationary and slower firing compared to other upgrades that do a similar task. Jungle Druids have been reworked to have more offensive power at both T3 and the T4 while not being quite so good at farming.
~ Ninja Kiwi
  • Buff 1xx Hard Thorns now allows Thorns to pop all Bloon Types
  • Buff 300 Druid of the Storm minimum blowback distance increased 33 -> 100
  • Nerf 300 Druid of the Storm maximum blowback distance reduced 300 -> 200
  • Buff 3xx Druid of the Storm tornado radius increased from 13 -> 16
  • Buff 5xx Superstorm price reduced from $90,000 -> 80,000
  • Buff x3x Vine grab now drops spiky thorns to the track upon popping a target
  • Buff x4x Jungle's Bounty can now grab 2 different Bloons at once
  • Buff x4x Jungle's Bounty ability cooldown reduced from 40 -> 60
  • Buff x4x Jungle's Bounty ability cash amount increased from 200 -> 240
  • Buff x4x Jungle's Bounty ability cash bonus per farm in radius increased from 100 -> 120
  • Nerf x4x Jungle’s Bounty: Cash Generating abilities now have a 3 minute timeout preventing further use in any single round

  • x-x-2 Heart of Vengeance save issues have been resolved.

  • Nerf Druid of the Storm blowback should correctly remove ongoing glue damage effects from Bloons when the slow is removed.



  • The second, third and to some degree its fifth upgrade of its path 1 were formerly upgrades of the Wizard Monkey in BTD 5.
  • The second and third upgrades share common naming patterns between all 3 paths: "Heart of X" and "Druid of X" respectively.
  • This is the second monkey in the main Bloons TD games that doesn't have brown fur (excluding heroes and non-monkey towers like the Tack Shooter.) The first was the Ice Monkey.
