There are strange things going on in your basement laboratories.
They keep calling up for more barrels of quicksilver or bits of your hair. Well it's all in the name of progress. They're looking for a way to turn lead into gold or at least into something better than lead. That lead had just been too good of a bargain to pass up, you didn't think, where will I put all this lead, what am I going to do with this lead anyway. Well that will all be sorted out. They're also looking for a universal solvent. If they manage that one, you will take whatever they use to hold it in and build a castle out of it. A castle that can't be dissolved. Now that's progress.
This is the 3rd addition to Dominion. It adds new Kingdom cards to Dominion and as it is an expansion, you will need Dominion or Dominion Intrigue to play the game. For 2 to 4 players. Play time of 20 minutes. Dominion Alchemy is an expansion and can't be played by itself, to play with it, you need Dominion or a standalone expansion to dominion (Dominion Intrigue).
