Now, some rule quoting.
Table 04.01: Attributes
0 Nonexistent — The quality is entirely lacking, such as the Cunning score of a coma patient, or the Strength score of someone with full body paralysis. The character is either dead or unplayable.
1 Poor — Cunning of young children or the mentally challenged, Strength of the small and frail.
2 Average — Physical scores of your average clerk or other sedentary occupation. Average mental scores for someone whose profession doesn’t require advanced training or education.
3 Good — A sharp mind, or the physical scores of someone who is considered “fit.” Body of someone used to labor or soldiering.
4 Impressive — Champion athletes or brilliant scholars. Upper level of what is possible for normal human development.
5 Awe-Inspiring — Pinnacle of human achievement, the type that exists once in a generation. Hawking, Conan.
Table 04.04: Skills
0 Untrained — You have no idea what you’re doing. Good luck.
1 Novice — Basic familiarity, but no practical experience. An enthusiast.
2 Apprentice — Beginnings of an education in a given craft. You know more than your average layperson, but are not yet competent.
3 Journeyman — Competent bordering on professional. You understand what to do, but lack the hands-on experience and tricks of the trade.
4 Master — Professional in your own right. People would pay you to do this. Most people never get past this level.
5 Grandmaster — The highest dedication to craft. The upper echelons of human achievement in a skill.
6+ Savant — The kind of skill that comes once a generation.
So far so good. The problem comes when you hit the Obs Table.
Table 02.02: Example Obstacles
Ob1 Trivial — Mostly meant for unskilled characters to succeed in basic tasks. Skilled characters don’t roll for these except for under dramatic circumstances — wounded, etc.
Ob2 Routine — Keeping one’s footing on a precarious surface; noticing you’ve wandered into the bad part of town, etc.
Ob3 Average — Getting a frightened horse team under control; quickly climbing a moderately high fence; busting down a regular door.
Ob4 Challenging — Calming a frenzied horse; navigating a ship through dangerous reefs using adequate maps; fishing with bare hands; general surgery.
Ob5 Hard — Bending soft iron bars or hinges; surgery concerning vital organs of the body; lifting a heavily laden cart off a child; busting down a secure, reinforced door.
Lets say you have attrib2 skill2 (average ratings). That's 4 dice. By reading the Obs table that means you will miss Routine tasks 50% of the time (Ob2) and passing Average skill checks is even harder.
To elaborate further you need a dice pool of 6 (stat3 skill3) for a 50% chance to pass average Obs.
Imo that is a bit too far.
