Larger Potions

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, hitting more bloons at once, and increasing pierce from 15 to 20. It costs $TBA on Easy, $TBA on Medium, $270 on Hard and $TBA on Impoppable.

Trivia

 * 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.
