Acid (status effect)

Acid is a status effect characterized by slowly corroding a bloon with acid. It is part of the damage types family. It has appeared since Bloons TD 6, with the introduction of the Alchemist.

Acid is represented on Bloons Wiki as, the upgrade artwork for Acid Pool in Bloons TD 6, which appears like an acidic splash.

Bloons affected by Acid will slowly be dealt damage every few seconds regardless of whether it was directly attacked by other attacks or not. Acid cannot stack with other variants of Acid but Stronger Acid's Acid status effect can replace the default Acid status effect. Rehitting the same bloon simply refreshes the Acid status effect, but only if affected bloon is affected by a greater than or equal strength of the current Acid status effect.

Only the Alchemist has the Acid status effect, and comes with this by default with its main attacks.
