Opening the small black and green box reveals a small rules insert. The rules add-on to the game are fairly simple and are about half a sheet of paper. Below that there are new dice and new cards. There are 20 new dice and 19 new cards. The new dice come in three different varieties, including a Corrupted Quiddity (10 dice), Demonic Overlord (5 dice), and Corruption Spell (5 dice). The cards offer some fantastic new variants to old favorite creatures as well as some new to this set cards. The old favorites from the original game are all "Corrupted" versions and use the original dice. For the original monsters there 10 cards, and for the new Demonic Overlord there are 4 different cards. The Corruption spell also has 4 different levels. The most interesting card is the Corrupted Quiddity. It is the first die to give you the chance to get a 0 for Quiddity on the roll... so you can roll and get nothing!
