Knowledge (INT; TRAINED ONLY)
- Answering a question within the character's field of study has a DC of 10 (for really easy questions), 15 (for basic questions), or 20 to 30 (for really tough questions).
- No. The check represents what the character knows, and thinking about a topic a second time doesn't let the character know something the character never learned in the first place.
- An untrained Knowledge check is simply an Intelligence check. Without actual training, a character only knows common knowledge.
