[quote=@Dynamo Frokane] I was considering that, but in a game with so many options leaving auto hit and auto fail success to a 2/12 chance is a little too simplistic. [/quote] Yes and no. A natural 1 will almost always be a fail. It's lower than any stat will be normally. A 12 is highest roll and cannot be beaten. They both fit. But more so, this allows you to modify your system to work on a D6 basis and lose one specialist dice. The 4 can be run a D12 with a divide 3 to simulate D4. Simplify is good... Not the enemy.
