One Inch Square

The D&D Compendium may be chock full of monsters, items, and powers, but one thing it still lacks is a list of the 4th edition diseases. If you’ve ever tried to put a disease in your game, you know finding them is quite a task: they are scattered about in a handful of different source books and articles with no index in which to look them up… until now.

Below is a compilation of most (if not all) of the 4th edition diseases to appear in any official source book, adventure, or DDI article to date. They are listed here broken down first by level for easy reference and then, in a separate set of tables, by source book, so you can quickly see what diseases are available in the books you have.

In a later post I will provide an index of some of the diseases created in 3rd party materials.
