Larger Potions

"Larger potions splash in a larger area."

- BTD6 description

Larger Potions is the first upgrade on the top path for the Alchemist in BTD6. It makes the potions thrown by the alchemist splash in a much larger area (from ~10 to ~20), hitting more bloons at once, and increasing pierce from 15 to 20. This also affects the pierce and splash radius most other potion attacks such as Unstable Concoction or Rubber to Gold, but it doesn't for Acid Pools.

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

Summary
Larger Potions adds both a greater splash radius and slightly more pierce for each potion. Greater splash area is helpful for a more reliable attack at hitting more bloons per shot, including for crosspathing benefits. The extra pierce provided by Larger Potions is also helpful for the same reasons.

Tips

 * Note that the damage of the potion remains the same, simply the Alchemist can hit more bloons, with a bigger area and a higher pierce. Stronger Acid is required to deal more damage.
 * This upgrade is important for Rubber to Gold, as it allows the goldify attacks to hit more bloons.
