So far I have no luck in general discussion, so I'll see if anyone here can aid me. I'm trying to find which product the concept of "degrees of success/failure" originated from. The concept is used in MM3e, and is based on their system for damage, however I'm not certain if this system originated from MM.
Not sure it originated there, but the damage system was also in Unearthed Arcana Injury. I think Green Ronin used it first fro their Blue Rose Game.
Tournaments, Faires, and Taverns?
