Transformation ability: Turns Alchemist into powerful [sic] attack Monster for 20 seconds.
~ In-game description

Transforming Tonic (also known as TT4) is the fourth upgrade of Path 2 for the Alchemist in Bloons TD 6. It grants an ability that transforms the Alchemist into a vicious monster for 20 seconds, temporarily replacing its main attacks with rapidly shooting blue fiery projectiles from its eyes and temporarily increasing range from 45 to 72. The super-powered blue plasma lasers are fired at every 0.03s (every 0.024s with Faster Throwing crosspaths), deal 3 damage to up to 6 bloons (9 with Larger Potions crosspaths) per plasma laser, and can pop any bloon type except Purple Bloons. Lasers can pass through Line of Sight obstacles. The Transformation cooldown is 60 seconds.

This upgrade costs $3,825 on Easy, $4,500 on Medium, $4,860 on Hard, and $5,400 on Impoppable.

Transforming Tonic

With this upgrade, the Alchemist changes quite visually. The Alchemist's coat becomes unbuttoned and ripped, places its goggles back onto its forehead, and a slightly crazed look can be seen in its eyes. However, the purple stain in its hair is removed.

When the ability is active, the Alchemist transforms into a blue-and-magenta monster, who, despite holding up fists in front of it like Ice Shards or later upgrades, fires blue lasers from its eyes. Each laser is shot every 0.03s (0.024s with 0-4-1), dealing 3 damage up to 6 bloons (9 with 1-4-0). These lasers are powerful enough to penetrate through obstacles, and the monster still can see through obstacles.

Transforming Tonic Ability

When activated, the Transforming Tonic ability turns the Alchemist into a vicious blue monster that shoots constant beams of hot blue lasers that pop lead for up to 20 seconds. All other attacks cease for the duration of the ability. Lasers deal 3 damage each, pierce up to 6 bloons (9 with 1-4-0), and pop Lead but not Purple. Cooldown of 60 seconds.

Like most magic-based activated abilities, Transforming Tonic's ability cooldowns can be reduced by adding a global Energizer buff or Obyn Level 12+. It can have its ability cooldowns reset with Geraldo's Rejuv Potion.

Targeting Priorities[]

Transforming Tonic's main attack throws potions in a lobbed arc at bloons according to targeting priority.

  • First: Targets the first bloon visible within its range.
  • Last: Targets the last bloon visible within its range.
  • Close: Targets the closest bloon visible within its range.
  • Strong: Targets the strongest bloon visible within its range.

The transformed monster shoots straight movement blue laser projectiles, and follows basic targeting priorities. Concoction potions have extended range and follow basic targeting priorities as normal.

Transforming Tonic gives the Alchemist the needed high DPS that it generally lacks, although limited to the ability. Whenever high DPS is necessary, one use of the ability will give it high damage overall, with an equivalent overall popping power of two Plasma Blasts Super Monkeys with triple pierce. The overall price of Transforming Tonic is highly expensive, but it is a cheap option when upgrading from an existing Unstable Concoction Alchemist, especially when crosspathed.


  • Note that once Transforming Tonic ability is activated, the Unstable Concoction bottles and the Alchemist's basic attacks are voided until the ability wears off.
  • Do not use this against Purple Bloons without support.
  • Transforming Tonic can see over walls and can shoot over them. Take into account straightline formations over curved locations for purposes of the lasers.
  • Crosspaths can improve the Transforming Tonic ability. 1-4-0 gives more pierce, while 0-4-1 gives extra attack speed. 0-4-1 is superior against single-target bloons, while 1-4-0 works better against grouped bloons.

Version History[]

Balance Changes[]

Due to reliance on its ability and simply the lack of direct single-target DPS of most Alchemists, the Transforming Tonic upgrade has been buffed to make its ability more useful at popping bloons.

  • BUFF Transforming Tonic price reduced ($5000 → $4500).
While the middle path T5 gets some use, T4 Transforming Tonic does not perform well for the low pierce amount so pierce has been increased.
~ Ninja Kiwi
  • BUFF Transforming Tonic plasma laser pierce increased (4 → 6).
Transforming Tonic has always had a large struggle with pierce, rather than directly throwing onto the base pierce we have added crosspathing pierce & rate benefits for transformation enjoyers to now choose between. [...]
~ Ninja Kiwi
  • BUFF 1-4-0 Transforming Tonic pierce increased (6 → 9)
  • BUFF 0-4-1 Transforming Tonic attack speed increased (0.03s → 0.024s)
[...] Transforming Tonic has been compared to being a worse but more expensive Turbo Charge, and that seems like a fair complaint. T5 has good niche uses, but T4 isn't worth the cost right now so we’re adding more juice to the tonic.
~ Ninja Kiwi
  • BUFF Transforming Tonic ability damage increase 2 → 3
Alchemist Transforming Tonic is in a weird spot with the transformation unable to attack through walls when the base alchemist is able to. Also with this, including a QoL fix for the T5 that currently prevents transformed towers from functioning with target priority.
~ Ninja Kiwi
  • BUFF Transforming Tonic transformed monster can now ignore Line of Sight
[...] Total Transformation alchemist when transformed have never been allowing damage to distribute to children layers of any targets, while this is an option we can use as an intended balance lever - we have instead decided to turn this blocker off as it isn't one we have used elsewhere and has made these upgrades perform far weaker against regular Bloons comparatively to Ceramic & MOAB-class due to damage buffs that have been given to transformed alchemists over time.
~ Ninja Kiwi
  • BUFF Transforming Tonic laser damage is no longer single-layer damage

Bug Fixes and General Changes[]

Extra Notes (Version History)[]


When activating Transforming Tonic Ability:


Official artwork[]



  • The description for Transforming Tonic is erroneously missing the word "a" between "into" and "powerful attack Monster", making the current description of the upgrade grammatically awkward.
  • Some players colloquially name the Transforming Tonic as "Cookie Monster", even though it bears little resemblance to it physically or behaviorally.
  • On 6th July 2021, the 2MPC combo for Transforming Tonic has been achieved on Logs.

Cultural references[]

  • This upgrade could potentially be a reference to the popular novel Strange Case of Dr Jekyll and Mr Hyde, where a chemist by the name of Dr Jekyll brews a concoction that transforms him into a monster (Mr Hyde).
  • The monster design resembles Pop Fizz from the video game Skylanders. Pop Fizz is a gremlin alchemist and is one of many Magic Skylanders. Pop Fizz is also known to transform into a more powerful and monstrous form as one of his attacks.
  • Alchemist's Transformation takes slight resemblance to Dr. Nitrus Brio from Crash Bandicoot where he can also turn into powerful monster.
