Science (3.5e Variant Rule)
From D&D Wiki
You are versed in a particular form of science. Like Knowledge, Science is actually a broad group of related skills, and you can have ranks in many different sciences.
Below are listed typical fields of study.
- Nuclear Physics
- Quantum Physics
- Robotics (constructs)
You should feel free to come up with additional Sciences with your Dungeon Master's approval.
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).
No. The check represents what you know, so thinking about a topic a second time doesn't let you know something you never learned in the first place. You can retry if you're able to research the topic for a while. The DM determines how much research is required for a retry, usually between an hour and a full day's work (depending on the complexity and obscurity of the topic).
An untrained Science check is simply an Intelligence check. Without actual training, a character has only common knowledge. The DM may rule that some Science checks are too specialized or difficult to attempt untrained.
