From publisher blurb:
Diseases are a part of life in every society, in every time period, and in every world. Most of them are pretty terrible - you drink the brown water, throw up a few times, and then die. Not exactly the makings of an adventure. But in a magical world, things are a little bit different - the diseases can be as exotic as the surroundings, and can serve as adventures all their own. The following is a collection of fantastic diseases, feats, and even a character class to help a GM add a different type of challenge to their campaign.
This supplement has includes:
10 All new disease including Black Touch, Dreaming Sickness, Logar Spawn and Therian's Whisper.
10 All New Feats including Breath Rot, Disease Sense, Contaminated Wounds and Infectious Spawn.
All New Prestige Class: Phage Touched
