If no Bloons are nearby Alchemist can drench nearby track with acid.
~ In-game description

Acid Pool is the 2nd upgrade of Path 3 (1st upgrade of Path 3 prior to Version 21.0) for the Alchemist in Bloons TD 6. It allows the Alchemist to create small, short-lived pools of corrosive acid near it to damage bloons when none are within its radius or if the Alchemist misses. Each Acid Pool can soak up to 5 bloons or last for 7 seconds before disappearing, whichever comes first.

This upgrade costs $380 on Easy, $450 on Medium, $485 on Hard, and $540 on Impoppable.

Strategy[]

Summary[]

Generally, Acid Pool can seem a bit weak, but the acid pools can be crosspathed with middle path to improve damage. While still fairly average, it is a cheap way to slightly improve MOAB and Ceramic popping power. Due to its situational purpose, it tends to be left out besides going for Lead to Gold or its further upgrades as a way for adding extra popping support.

Tips[]

  • Once 5 bloons pass over a pool, it is used up and all bloons hit become soaked in acid, having a similar effect as if it was splashed manually, dealing a total of 3 damage, 1 damage from the initial hit plus 2 layers of damage over 4.0 seconds.
  • The pools cannot pop Camo Bloons if the Alchemist does not have camo detection.
  • The AcidStabilityIcon.png Acid Stability MK increases the lifespan of the pools by 5 seconds, massively boosting its potential.
  • Acid Pool can contribute to lag. Avoid using this upgrade in extremely laggy situations such as Freeplay Mode. Although for Permanent Brew it is not much a problem, as Acid Pool is usually skipped anyways, it can be very tempting to add it to Unstable Concoction.

Version History[]

Acid Pool was swapped with Faster Throwing in Version 21.0. Arguably, this upgrade is overall nerfed, as the acid pool attack is overall more expensive to obtain.

21.0
Follow up steps in overall balancing use of the 420 and 402 alchemist upgrades, this brings both combinations more in-line for total cost and allows us to think about Acid Pools as its own upgrade in future rather than worrying about the impact of changing 402.
~ Ninja Kiwi, referring to Alch buff crosspath balance
  • Change Acid Pool and Faster Throwing are now swapped.
  • Buff Acid Pool costs less ($600 → $450).

Trivia[]

  • This upgrade is also affected by Stronger Acid and will change its visual design from red to purple and have similar damage.
  • The acid pool is not affected by Larger Potions.
  • If an acid pool potion hits a Camo Bloon without Camo detection, it will splash where it hit. This can limit where acid pools are thrown and the acid pool can sometimes be partially off the track.
