Justice and Rule
Legend
I've houseruled that Inspiration is awarded on a roll of 1. I took that idea from Cortex, where a failure can boost your chance of future success.
The new Legend of the Five Rings system has something like this, where if you fail because of your flaw/disadvantage, you gain a "void point" which gives you bonuses for other things. Helps get people to not avoid their character flaws, and roleplay better.
