Lively concoction is a green alchemical healing liquid crafted with three random ingredients chosen at the start of each game or it can be found randomly inside a chest. It quickly heals the player over time when stained by it.
The substance evaporates into nothing on its own, so make use of it quickly. You only need a very small amount of it to trigger the heal, however.
Causes a small explosion on contact with Purifying Powder. This is capable of destroying the wood of the giant tree.
