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 some typical fields of study (there are hundreds of them).


 * Alien Cultures (The Tollan, the Nox, the Asgard, the Goa'uld, the Ancients)
 * Ancient Cultures (Ancient History, Ancient Egypt, Ancient Britain, Ancient Turkey, Ancient Greece, etc.)
 * Current Events: Recent happenings in the news, sports, politics, entertainment, and foreign affairs.


 * Engineering (buildings, aqueducts, bridges, fortifications, Technologies)


 * Geography (lands, terrain, climate, people)


 * History (wars, colonies, migrations, founding of cities)


 * Local (legends, personalities, inhabitants, laws, customs, traditions, humanoids)


 * Nature (animals, fey, monstrous humanoids, plants, seasons and cycles, weather, vermin)


 * Popular Culture (Popular music and personalities, genre films and books, urban legends, comics, science fiction, and gaming, among others.)
 * Physical Sciences (Chemistry, Physics, Astrophysics, Oceanography, Quantum Physics)
 * Social Sciences (Anthropology, Archaeology, Paleoanthropology)
 * Earth and Life Sciences (Biology, Botany, Embryology, Genetics, Geology, Paleontology)
 * Medical Science (Pathology, Anatomy, Toxicology)


 * Religion (gods and goddesses, mythic history, ecclesiastic tradition, holy symbols, undead)
 * Streetwise: Street and urban culture, local underworld personalities and events.
 * Tactics -- Techniques and strategies for disposing and maneuvering forces in combat.
 * Technology: Current developments in cutting-edge devices, as well as the background necessary to identify various technological devices.
 * U.S. Military (Officers, Procedures, Ranks, Methods)
 * U.S. Politics (Watch your back, Jack)

Check: Answering a question within your field of study has a DC of 10 (for really easy questions), 15 (for basic questions), or 20 to 30 (for really tough questions).

You can use this skill to identify monsters and their special powers or vulnerabilities. In general, the DC of such a check equals 10 + the monster's CR. For common monsters, such as goblins, the DC of this check equals 5 + the monster's CR. For particularly rare monsters, such as the tarrasque, the DC of this check equals 15 + the monster's CR, or more. A successful check allows you to remember a bit of useful information about that monster. For every 5 points by which your check result exceeds the DC, you recall another piece of useful information. Many of the Knowledge skills have specific uses as noted on Table: Knowledge Skill DCs.

Action: Usually none. In most cases, a Knowledge check doesn't take an action (but see “Untrained,” below).

Try Again: No. The check represents what you know, and thinking about a topic a second time doesn't let you know something that you never learned in the first place.

Untrained: You cannot make an untrained Knowledge check with a DC higher than 10. If you have access to an extensive library that covers a specific skill, this limit is removed. The time to make checks using a library, however, increases to 1d4 hours. Particularly complete libraries might even grant a bonus on Knowledge checks in the fields that they cover.
