Alchemist is the hero constantly mixing and making potions.
Witch Doctor is the hero who's flings his cask around at people.
So you decide to do this instead to nature's profit/shadow shaman.
Why? Please reread the rules next time, here is a link to the heroes mentioned in this thread.
Constantly concocting potions.
Uses his cask to paralyze his enemies.
Raised by a con man pretending to do magic
Protector of the forest.
Why did you go with the ones that have no relation to potions at all?
