Knowledge
Knowledge (Int; Trained Only)
You are educated in a field of study and can answer both simple and complex questions. Like the Craft, Perform, and Profession skills, Knowledge actually encompasses a number of different specialties.
Below are listed the fields of study added for this campaign.
Knowledge (forbidden lore) [Int]: This entry specifically relates to some of the inner workings of reality itself. Even a tiny glimpse into these realms can cause a creature to go mad, so every rank in this skill permanently reduces a character's maximum Sanity score (if it has one) by one point. Ranks may be taken only with GM permission, and usually require particular study or harrowing experience.
Knowledge (geology) [Int]: This entry specifically relates to the study of rocks, minerals, and geologic processes. Knowledge (geography) and Knowledge (dungeoneering) each touch on some bits of geology, but Knowledge (geology) delves further into the processes behind the features and includes other all other fields which fall under "earth sciences."
