The Wild Nature (fan expansion for Potion Explosion; TWN) is an Unofficial Fan-made Print and Play expansion for the Potion Explosion Boardgame (it is not a project by Horrible Games, the publisher of Potion Explosion). TWN introduces a new Ingredient - Wild Nature Essence (green marbles), a new board - Nature Leaf, 4 new Potions and 9 new Professors. Wild Nature Essence - when activated in an Explosion - will trigger a Wild Explosion (between different colored marbles). This will enhance the Explosion possibilities and your brewing Potions abilities. The new Potions, and the newly arrived Professors each with their unique view on brewing Potions, both add more variety to the game. You can download the rules and components from the files and adding 12 green marbles (you must provide them) you have this new expansion ready! -description from designer
