(Intelligence Based Skill; Trained Only)

This skill encompasses several categories, each of them treated as a separate skill. These categories are identified and defined below.

Check: A character makes a Knowledge check to see if the character knows something.

The DC for answering a question within the character’s field of study is 10 for easy questions, 15 for basic questions, and 20 to 30 for tough questions.

Appraising the value of an object is one sort of task that can be performed using Knowledge. The DC depends on how common or obscure the object is. On a success, the character accurately identifies the object’s purchase DC. If the character fails, he or she thinks it has a purchase DC 1d2 higher or lower (determine randomly) than its actual value. If the character fails by 5 or more, he or she thinks it has a purchase DC 1d4+2 higher or lower than its actual value. The GM may make the Knowledge roll for the character, so he or she doesn’t know whether the appraisal is accurate or not.

The Knowledge categories, and the topics each one encompasses, are as follows.


Business procedures, investment strategies, and corporate structures. Bureaucratic procedures and how to navigate them. (Business Checks)


Art: Fine arts and graphic arts, including art history and artistic techniques. Antiques, modern art, photography, and performance art forms such as music and dance, among others.

Current Events: Recent happenings in the news, sports, politics, entertainment, and foreign affairs.

Popular Culture: Popular music and personalities, genre films and books, urban legends, comics, science fiction, and gaming, among others.

Streetwise: Street and urban culture, local underworld personalities and events.

(Culture Checks)

Life Science:

Biology, botany, genetics, geology, and paleontology. Medicine and forensics. (Science Checks)

Physical Sciences:

Astronomy, chemistry, mathematics, physics, and engineering.


Events, personalities, and cultures of the past. Archaeology and antiquities. (History Checks)


Behavioral Sciences: Psychology, sociology, and criminology.

Civics: Law, legislation, litigation, and legal rights and obligations. Political and governmental institutions and processes.

Theology and Philosophy: Ethics, philosophical concepts, and the study of religious faith, practice, and experience.

(Society Checks)


Techniques and strategies for disposing and maneuvering forces in combat. (Tactics Checks)


Current developments in cutting-edge devices, as well as the background necessary to identify various technological devices. (Tech Checks)

You can make a Knowledge (tech) check to correctly identify starships, mechs, robots, and bionic attachments, as well as identify unfamiliar technological devices.

Check: The DCs for identifying technological items vary depending on the type of information required:

Identifying a starship by its type and subtype, identifying a mech by its superstructure, or identifying a robot by its frame: DC 10.

Determining the function or purpose of a particular mechanical system or bionic attachment: DC 15.

Recalling the standard, factory-model design specs of a particular type or class of starship, mech, or robot: DC 20.

When confronted with an unfamiliar piece of technology or alien artifact, you can make a Knowledge (tech) check to correctly surmise the primary (if not singular) purpose of the device. A successful check result does not enable you to activate the item, nor does it make you proficient with the item. The DC of the Knowledge (tech) check depends on the item being identified, species of the creator, and the level of sophistication.

Unfamiliar Item DC
Basic tool or instrument 10
Robotic or vehicular component 15
Bionic attachment 20
Alien weapon or nanotechnology 25
Alien artifact 30

Try Again?: No. The check represents what a character knows, and thinking about a topic a second time doesn’t let the character know something he or she never knew in the first place.

Special: An untrained Knowledge check is simply an Intelligence check. Without actual training, a character only knows common knowledge about a given subject.

A character with the Educated feat gets a +2 bonus on any two types of Knowledge checks.

Time: A Knowledge check can be a reaction, but otherwise requires a full-round action.
