Regardless of the knowledge skill you’re using, refer to the rules here when making a knowledge check. Another use of the knowledge skills is for Monster Knowledge Checks.
Common Knowledge: This includes the kind of general information that is commonly known about a given topic.
Expert Knowledge: This includes the kind of specialized information that only an expert in the field of study could possibly know.
Master Knowledge: This includes the kind of esoteric information that only a master in the field of study could possibly know.
Check[]
- Knowledge Skill: No action required—either you know the answer or you don’t.
- DC: Varies. General information is based on an Easy DC, Specialized as a Modeate DC, and Esoteric would be a Hard DC.[RC:129]
- Success: You recall a useful bit of information in your field of knowledge or recognize a clue related to it.
- Failure: You don’t recall any pertinent information. The DM might allow you to make a new check if further information comes to light.
