Elixir

The Elixir is a new "road" item that can make towers shoot 50% faster for 10 seconds. The cost of an elixir is 10% the cost of the tower it's used on, including upgrades (when hovered above a tower, a price will appear near the "elixir cursor"). Despite being a potion of sort, this work for even vehicles and buildings.

Trivia

 * The Elixir even works with vehicles and buildings because it has a special substance that can interact with the mechanical structures of the monkeys' vehicles and buildings.
 * In the "shop panel", the price of the Elixir reads "10% of tower cost"
