You don’t need a potion. Just need a script or program. It is easy really.
As we are talking about mana. It seems, as the book imply, that plants has mana too. Are plant mana the same as animal mana? Also, is demon mana very much the same as human manas? People can’t seem to tell a demon pretending to be a human from real humans.
Also, could people somehow use plant mana to do magic?
