Many years ago, I bought a game called 'Elixir', in which the players represent wizards trying to obtain the ingredients for the Elixir of Life.
Unfortunately, I've lost the rules, and I can't find any reference to the game or its manufacturers on the Internet.
The main thing I need to know is the table that tells you the result of an attempt to brew a potion, based on the value of gems in the mix, and the die roll you throw.
