"Showers enemies with acid"

Acid Rain is an alchemy formula. It is taught by an alchemist at the Sandpits. After defeating Thraxx to gain access to the cliff area of the Sandpits, a hidden area to the right of the pot containing Wax leads to the alchemist.

Usage[edit | edit source]

Acid Rain executes quickly and fires no projectile, taking effect on targeted enemies almost instantly. It douses them with water for a couple of seconds, during which time they are invulnerable.

Acid Rain has the longest duration to deal damage.

Acid Rain is decently effective when first acquired. It does more damage on average than Flash and Hard Ball, the other two offensive formulas acquired in Prehistoria, and also has the advantage that the ingredients needed to cast it are much more common and less expensive than the ones for Flash and Hard Ball. However, prolonged usage of it is ill-advised, as Acid Rain consumes 3 Water with each use and can quickly burn through the player's stock, and Water is needed for another important formula, Heal.

Ingredients[edit | edit source]

Acid Rain requires 1 part Ash and 3 parts Water for each casting.

Trivia[edit | edit source]

Acid Rain Firepit.png

  • A Firepit can be seen at the location of the Acid Rain alchemist, beneath the cliff. It is not lit and never becomes lit, even after the point when Tinker Tinderbox explains how they work.
  • Thraxx may sometimes cast this on Maggots in the boss room. This is a rare bug.
  • Acid Rain, Revive, and Corrosion are the only 3 alchemy formulas in the game that require 3 of an ingredient.
