Ball Lightning is the Druid's path 1 tier 4 upgrade in Bloons TD 6. It gains camo detection and grants an additional attack that summons a slow-moving lightning ball, which quickly zaps lightning at Bloons and freezes Bloons that touch the lightning ball. This attack is shot every 6 seconds, and generates lightning every 0.35s, forks up to 5 times (up to 31 targets total), and does 3 damage. The ball does no damage, and freezes any non-White type for 4.5s through up to 4 layers of Bloon.

Additionally, the ordinary Heart of Thunder lightning bolts deal 3 damage, and tornadoes are more effective. Tornadoes now blow back Bloons +50 more units backwards (150–250 units), and has its pierce increased from 35 to 60 with no pierce penalty versus Ceramic Bloons.

Ball Lightning is a decent mid-game tower for both support and damage, controlling and popping Bloons that follow its path. However, multiple T3 Druid of the Storms are generally more versatile for blowback despite the more cost-efficient blowback of the T4. Ball Lightning's lightning balls can be used for dealing general damage to any non-Purple when placed along straight lines, however the ball is antithetical for the purpose of prolonging rounds to use abilities. The lightning ball freeze benefits Bloon control especially with Cold Front's zap freezes, but remains not enough to be a proper stall tower, and its slow attack speed and reliance on straight lines on CHIMPS prevents it from working on many map formats.

Version 23.0

•  Upgrade cost reduced ― $6,000 → $5,500

Version 25.0

“

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.
— Update notes

”

•  Upgrade cost reduced ― $5,500 → $5,100
  •  Overall cost reduced by $550 (due to cost changes for previous tiers)

Version 26.0

•  Tornado: blowback should correctly remove ongoing glue damage effects from Bloons when the slow is removed (bug fix)

Version 28.0

“

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.
— Update notes

”

•  Main attack: Damage type changed ― Shatter → Normal
•  Tornado attack: Blowback distance changed ― 33–300 → 100–200
•  Tornado attack: Projectile radius increased ― 13 → 16

Version 30.0

“

Top path has had a number of buffs to help with both price and consistency in control over regular bloons through higher tiers.
— Update notes

”

•  Upgrade cost reduced ― $5,100 → $4,500
  •  Overall cost reduced by $825 (due to cost changes for previous tiers)
•  Tornado: Blowback distance increased ― 100–200 → 150–250
•  Tornado: Pierce increased ― 30 → 60
•  Ball Lightning (main projectile): Now has a 25% chance to freeze Bloons (same as the original effect of Cold Front)

Version 33.0

“

Top path Heart of Thunder doesn’t scale well with tiers for an upgrade with such niche use & generally feels lacking, so it is seeing general power improvements across the board to upgrades that incorporate this attack.
— Update notes

”

•  Heart of Thunder: Damage increased ― 1 → 3
•  Ball Lightning: Damage increased ― 2 → 3

Version 37.0

“

While the tornado doesn't do anything to MOABs, it still spends itself on them which wastes a relatively long cooldown, so addressing this flaw.
— Update notes

”

•  Tornado: no longer targets MOAB-class Bloons
  • Note: This is a buff as the tornado does not affect MOAB-class Bloons

Version 38.0

“

Druid of the Storm is too inconsistent due to placement causing projectiles to intersect the path and spend very little time actually touching Bloons, it is gaining some homing to keep the nados running along the track over the top of Bloons to more consistently utilize their high pierce value. We love how this is working and hope you do, too.
— Update notes

”

•  Tornado: Now seeks Bloons
•  Tornado: Maximum travel distance increased ― 80 → 100
•  Blowback no longer works on Bloons near the entrance (bug fix)

Version 39.0

•  Lightning Ball: Freeze chance increased ― 25% → 100%

Version 44.0

•  Ball lightning projectile can no longer freeze White Bloons by default (bug fix)

Version 45.0

“

Now that Tornadoes are one of the more popular Bloon Stall choices we looked more into its upgrade progression, tornado projectile speed is being reduced as a benefit to Ball Lightning to prevent tornado outpacing the lightning ball so quickly, and to more suit it as a Cold/Magic themed upgrade plus differentiate from similar supports the weaknesses are changing. More directly to Ball Lightning we feel it needs a considerably higher freeze duration for the freeze to matter as it casts slowly.
— Update notes

”

•  Ball lightning: freeze duration increased ― 1.5s → 4.5s
•  Tornado: projectile speed reduced ― 90 → 72
•  Tornado: damage type changed ― Normal → Frigid
  • Note: Does not affect the mini-tornadoes of Tiny Tornadoes
•  Tornado: can blow back Lead Bloons
•  Tornado: cannot blow back White and Purple Bloons
  • Note: Projectile will ignore White and Purple properties, which it cannot target anymore

Version 48.0

“

Druid projectile lifespans are being shifted from many base weapons into the xx1 range crosspath, this is a nerf to top path lifespan when not taking the crosspath and a buff to 031 druids
— Update notes

”

•  Ball Lightning: Projectile distance reduced ― 120 → 90
  • Note: xx1 crosspath unchanged
•  Thorn: Projectile distance reduced ― 136 → 102
  • Note: Does not affect X-X-1, implemented as a projectile lifespan decrease ― 0.4s → 0.3s
•  Tornado: Projectile distance reduced ― 100 → 75
  • Note: xx1 unchanged

Version 54.0

“

Also expanding on the support capabilities of this path, we’ve given Ball Lightning’s freeze more than 0 radius so it can hit things, and have pulled Monarch’s Camo detection down to Tier 4 to allow early Camo assistance outside of Obyn strategies.
— Update notes

”

•  Ball Lightning main projectile: Projectile radius increased ― 0 units → 8 units
•  Ball Lightning main projectile: Damage type changed ― Cold → Frigid
•  All attacks now have Camo detection
• Description changed

Before	Creates powerful balls of lightning that can freeze Bloons. Additional lightning bolts arc off main attack to nearby Bloons.
After	Able to perceive Camo Bloons. Creates powerful balls of lightning that can freeze Bloons. Additional lightning bolts arc off main attack to nearby Bloons.

Version 54.1

•  Ball Lightning: Projectile now ignore Bloons if its damage type cannot damage them

Version 54.2

•  Ball Lightning main projectile: No longer prevents MOAB-Class Bloons from being frozen after touching them (bug fix)

Version 55.0

•  Main attack: Projectile spread can now be affected by accuracy buffs
