one roll, one choice

 FMC Basic does away with ability scores (quite rightly!), but you might still want something of the sort. But we're doing one roll, one choice.

1. strong, fast, tough
2. strong, fast, smart
3. strong, fast, wise
4. strong, fast, charming
5. strong, tough, smart
6. strong, tough, wise
7. strong, tough, charming
8. strong, smart, wise
9. strong, smart, charming
10. strong, wise, charming
11. fast, tough, smart
12. fast, tough, wise
13. fast, tough, charming
14. fast, smart, wise
15. fast, smart, charming
16. fast, wise, charming
17. tough, smart, wise
18. tough, smart, charming
19. tough, wise, charming

Keep two; the other becomes a flaw. 

• Strong characters deal +1 physical damage. Weak characters can't tempt fate to force doors, jump gaps, or the like.
• Fast characters get +1 on attack rolls. Clumsy characters can't tempt fate to go before their foes.
• Tough characters get +2 HP. Sickly characters can't tempt fate to resist poison, avoid disease or the like.
• Smart characters get +1 capacity. Dull characters have -1 capacity.
• Wise characters get +1 defense if they are not surprised. Foolish characters are still surprised if their party tempted fate to avoid it.
• Charming characters can re-roll a negotiation roll; if it changes from negative to affirmative there will be some additional quid pro quo. Off-putting characters must tempt fate to avoid making a bad impression when meeting someone new.
