Stronger Acid

"Acid potions dissolve Bloons faster."

- In-game description

 is the first upgrade on the second path for the Alchemist in Bloons TD 6. It makes the acid effect applied by the Alchemist (and any acid pools formed if that upgrade is purchased) deal overall increased damage, increasing its damage rate from 2.0 to 1.5 seconds, as well as increasing the duration of the acid effect from 4.0 to 4.5 seconds, giving the acid 3 damage ticks.

Unlike the name of the upgrade, the Stronger Acid upgrade doesn't improve Acidic Mixture Dip buffs; rather, its upgrade Perishing Potions does this.

It costs $210 on Easy, $250 on Medium, $270 on Hard, and $300 on Impoppable.

Appearance
This upgrade gives the Alchemist white gloves.

Summary
Dissolving bloons faster is useful in the early-game to let the affected bloons pop faster by the acidic damage-over-time effects.

Tips

 * When this upgrade is combined with either Acid Pool or Larger Potions, it becomes a moderately powerful tower early game against grouped bloons.
