Transformation ability: Turns Alchemist into powerful attack Monster for 20 seconds.
~ BTD6

Transforming Tonic is the fourth upgrade of Path 2 for the Alchemist. It allows the Alchemist to transform into a vicious monster for 20 seconds, rapidly shooting blue fiery projectiles from its eyes. The super-powered blue plasma lasers are fired at a rate of ~33.3 times per second, deal 2 damage to up to 4 bloons per plasma laser, and can pop any bloon type except Purple Bloons. Unfortunately, similar to most Alchemists, camo detection is required to allow popping of Camo Bloons. Cooldown for Transforming Tonic is 60 seconds (approximately 1/3 uptime).

It costs $3825 on Easy, $4500 on Medium, $4860 on Hard and $5400 on Impoppable.


  • 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.
  • It is worth noting that Transforming Tonic will NOT ignore Line of Sight, meaning that obstacles that may normally not block the Alchemist will now block its firey lasers when in Alchemist Monster form, even if the Alchemist Monster can detect bloons through such obstacles.
  • Do not use this against Purple Bloons without support.
